Today on our 2005 Acura MDX well be installing the Tekonsha Prodigy P2 brake controller part #: 90885 in conjunction with the e-trailer ETB C7 brake controller install kit part #: ETB C7. To begin our install well first locate the four pole trailer connector. Its already mounted on the vehicle. Its stored here in the rear cargo area. Well need to rout it outside the vehicle. To do this were going to go ahead and remove the rear threshold.
To remove the rear threshold well remove the two push pin fasteners and then get underneath the threshold and pry it up being careful not to break the fasteners underneath. Next well locate the grommet here underneath the threshold. Well go ahead and remove the grommet and take the four pole connector and feed it inside. Now well get underneath the vehicle and remove a secondary grommet where we can now locate the four pole and pull it through the holes. Now with the four pole connector routed outside we can begin installing the new seven pole connector.
Well take our seven pole and seven pole bracket, feed the bracket over the wiring and bring it up to the face of the seven pole. Then, using the hardware provided by our install kit we can go ahead and secure the bracket to the seven pole. Next well take the four pole and mount it to the side of the seven pole bracket. Next, well take the seven pole bracket and mount it to the Tow Ready no-drill mounting bracket part #: 18140. Now were ready to secure the seven pole bracket to the hitch.
Well use the worm gear clamp provided to secure the bracket directly to the hitch. Put the bracket into position noting that we turned the bracket upside down to fit this application. Put the worm gear around the hitch and bracket and go ahead and tighten it down. Next, we can take the four pole connector coming from the back of our seven pole and the four pole thats already mounted on the vehicle and connect the two. I recommend to use some Edelman dielectric grease in between these two connections.
The Edelman dielectric grease part #: 11755 will help prevent corrosion in between your electrical connection points. Now as the two four poles are connected well go ahead and clean off any of the extra dielectric grease and smear it into the bud connectors for the blue and black power wires. Additionally to secure these two four pole connectors together well take one of the black zip ties from our install kit and wrap it around the four poles and then cut off the excess. Next, well take the gray duplex cable, well strip back several inches of sheathing and then strip back two wires. Now we can connect the white wire to the blue wire from our seven pole connector and the black wire to our black wire coming from our seven pole connector. These two wires will be routed to the front of the vehicle and up into the engine compartment. The black wire will be power for our seven pole and the blue wire coming from our seven pole connector that attaches to the white wire in the gray duplex cable will be the hot lead for our trailer braking system. Now with all these connections made well go ahead and take some black electrical tape and wrap up our connection points to help keep out the dust, dirt, debris and moisture. Next well need to ground the seven pole connector. Well take the white wire with the pre-attached ring terminal and use the manufacturers welded nut here in the bumper structure. Now with our ground secured well go ahead and start routing our grey duplex cable. The help us rout our gray duplex cable were also going to use Redline metal loom clamp part #: A0500 and a self-tapping screw and secure it here, at the rear cross member. Remember, when routing your wires stay away from moving components such as the steering or suspension, or excessive heat such as the exhaust. Also keep in mind, as we rout our gray duplex cable well use the black zip ties provided with our install kit to secure our wiring. Now that weve got the gray duplex cable run to the front well need to run it to the top of the engine bay. To assist well use a pull wire or in this case a piece of air tubing or a stiff piece of wire to rout it up through the engine bay. Then well connect the tubing to our gray duplex cable with some black electrical tape and pull it to the top of the engine compartment. Now well go ahead and get back underneath the vehicle and to clean up our install look well cut off the excess from the zip ties. Well also need to reinstall the manufacturers grommet that we removed to run the four pole that was already previously attached to the vehicle. To do this well take our side cutters and cut a slice in the grommet. Then well slide the wire into the slice and reinstall the grommet. To prevent any intrusion from the outside of the vehicle we recommend to seal up this cut with the Loctite RTV gasket maker part #: LT37467. Well go back to the inside of our cargo area, cut a slice in the interior grommet, reinstall it and reinstall our threshold. Well go ahead and close the rear cargo cover and rear hatch. Now well move to the front of the vehicle where weve got our gray duplex cable. Well go ahead and secure it with a black zip tie, measure our wire, our approximate length needed to run inside the vehicle and cut off the excess. Then well go ahead and strip it back as well take the white wire and run it through the manufacturers grommet here in the firewall so that we can ultimately run it to our brake controller. To run through this grommet well go ahead and use our utility knife and cut a hole in the grommet. Then we can go ahead and push the white wire through. Next well take the leftover gray duplex cable that we just cut off and rout it through the grommet as well to feed power and ground to our brake controller. Now lets go ahead and move inside the vehicle. Well need to remove the underbody panel here for the dash. Well unlock it, pull it down, remove the two electrical connections by pressing on the locking tab and then removing the connectors from the socket. Once thats done well remove the underbody panel and set it aside for reinstallation later. Now well go ahead and locate the gray duplex cable and white wire that we ran inside the vehicle. Now well go ahead and mount the brake controller bracket using the hardware provided with the install kit. Well go ahead and take the brake controller pigtail and the red wire from our pigtail that will need to be secured to the manufacturers brake switch power. To locate this well go ahead and use a test light. Turn the key in the on position, but not starting and back probe the brake switch till we locate the wire that is only hot when the brake pedal is depressed. Now weve located this wire. There are two wires going to this connection point. Theyre both white wires with a black tracer and gray dots. To make it easier to access this wire well go ahead and remove it from the brake switch. Well press on the locking tab and then remove it. Now well need to remove the tape covering up the wires. Well use our utility knife to cut the tape and pull it away. Then well go ahead and pull one of the white wires with the black stripe and the gray dots away from the bundle and install a quick splice connector. Once we install the connector we can then take the red wire and feed it into the back of the quick splice and cramp it down. Well go ahead and close the clasp and then tape up the wires. Once we do that we can go ahead and reinstall the connector back into the brake switch socket. Next, well take the white wire that we ran, coming from the back of the seven pole connector and attach it to the blue wire from our brake controller pigtail. Well go ahead and cut to length as needed, strip it back and add a yellow bud connector. Then well take the blue wire from the brake controller pigtail and secure it to the other end of our bud connector. Now with the red and blue wires connected from our brake controller pigtail well go ahead, strip back the gray duplex cable and strip back both wires inside. Then we can match color for color, black to black and white to white for the brake controller pigtail using the bud connectors provided with our install kit. Next, with all our connections made well want to wrap up our connection points with some black electrical tape, keeping out any dust, dirt, debris or moisture. Then well go ahead and take our black electrical tape and wrap up the brake controller pigtail which will help bundle up our wires and help clean up our install look. Now with that done well go ahead and take our brake controller pigtail, feed it up through the brake controller pocket and install it into the back of the brake controller. We can then drop the brake controller into the pocket and lock it in place. Next, well take the zip ties provided with our install kit and secure our wiring up underneath the dash. Cut off the excess from the zip ties to clean up our install look. We can then reinstall the interior panel we removed earlier. Well now move back to the engine compartment. Well take the black wire that we ran with the gray duplex cable and rout it over to the drivers side fender well. Here well mount a 40 Amp breaker thats provided with our install kit using the self-tapping screws provided with our install kit. Now with our 40 Amp breaker mounted well go ahead and mount a 20 Amp breaker for our brake controller. With both breakers mounted well take the black wire that we ran from our gray duplex cable, strip it back and add a small ring terminal and then add it to the silver side to the 40 Amp breaker, securing it with the star washer and nut. Next, well take the gray duplex cable that we ran inside for power and ground for our brake controller and rout it over and past our breakers and ultimately to the negative battery cable. There we can go ahead and cut off the excess from the gray duplex cable, strip it back so that we can rout the black power wire to our 40 Amp breaker and the white wire to the negative battery post. Once we have the white wire routed well go ahead and strip it back and add a large ring terminal. We can then remove the nut on the positive battery post terminal, install the ring terminal and then re-secure the nut, completing the ground for our brake controller. Well back to the power wire that we ran inside that gray duplex cable, strip it back, add a small ring terminal, sliding it over to the silver side of our 20 Amp breaker and securing it. Next well need to make two hot leads for our breakers. This will go from the copper side of our breakers to the positive battery post terminal. Well take the leftover black wire from our gray duplex cable to make these two hot leads. Well strip back one end adding a small ring terminal and then secure it to our 40 Amp breaker. Ill then rout it over to the positive battery terminal where I can cut off the excess and add a large ring terminal. Then taking the leftover wire, well strip it back again, add a small ring terminal and add it to the copper side of my 20 Amp breaker. As I rout this wire well also secure our wires with the zip ties that are provided with our install kit. Once we complete the routing well go ahead and strip it back and add a large ring terminal. Well then remove the nut on the positive battery post terminal, install our two ring terminals and then re-secure the nut. Well go ahead and cut off the excess from our zip ties to clean up our install look and this will complete the installation of the Tekonsha Prodigy P2 brake controller part #: 90885 in conjunction with the e-trailer ETB C7 brake controller install kit part #: ETBC7, Tow Ready no-drill mounting bracket part #: 18140, Edelman dielectric grease part #: 11755, Loctite RTV gasket maker part #: LT37467 and our Redline metal loom clamp part #: A0500 for our 2005 Acura MDX.
Average Customer Rating: 4.8 out of 5 stars (82 Customer Reviews)Protect your electrical connections with this specialized formula that combats corrosion from water damage. Electrical Contact Grease comes in a 2 oz. tube.
Dielectric grease is the best lubricant for your electrical contacts on fuses, plugs, etc. Once the contact has been cleaned and dielectric grease applied the contact's will not corrode nor does it inhibit or degrade the flow of electricity thru the contacts. This grease is also very water resistant. This product is a full 2oz which is unusual as most auto supply shops etc. only carry the smaller, much smaller sizes.......and I alway's seem to run out. Etrailer was very quick with delivery of the product......as alway's. 28508

Great amount of grease for the price. Tips: Use the end cap on your 4-pin wiring connector to keep dirt and such from getting collected by the grease when the wiring harness is not in use. Also use a snack bag and rubber band to wrap the connector on your trailer when it is not in use to keep gunk out. 140125
by: Ron B.09/20/2012
I always use dielectric grease on all my plug connections to solve the corrosion problem. I live in Ohio and the salt on the ATV trailer does ruin cheaply done wiring connections. Worth the time and effort to not have to trouble shoot problems later in the wiring. 55251
I had three vehicles with hitches in the past that all had green 4 pole trailer connectors from corrosion. So far, this grease has kept that from happening. It is much easier to get the harnesses together and apart now, too. Well worth the money. 24958

DIELECTRIC GREASE I HAVE NOT TRIED THIS TYPE OF PRODUCT BEFORE BUT FROM PAST EXPERIENCE I KNOW THAT TRUCK & TRAILER WIRING CONNECTIONS TAKE A BEATING. THIS SHOULD HELP KEEP OUT WATER & CORROSION. 4252
by: V Wardlaw05/11/2011
I received my product in a timely manner. The product works very good. I've used it on several electrical connections such as vehicle tail lights and trailer lights. Works Great. 13581
by: Devin F11/09/2012
Shipping was extremely fast, the only problem I had was the color wires coming out of the plug were not hooked to the correct pins that is typically used for trailer wiring. 59128
A good inexpensive way to help prevent corrision from water & other contaminants on your trailer electrical connections & makes it smoother to to attach and detach them 66963
After struggling to get previous corroded electrical connectors apart, I am looking forward, to avoiding that scenario in the future, with the dielectric grease. 123235
by: Steve C03/21/2014
It's electrical grease... in a tube. Works as advertised. I use it all over the plaqce, including to lube those pesky sticky light bulb sockets, 121691
What can I say..... It works great. Keeps the connector clean, no corosion on contacts. Always works when you plug in the connector. 140401
This dielectric grease works wonders not only on my trailer connectors. But works equally as well on other automotive connectors.. 94950
This is an excellent way to insure you can take connectors apart in the future and that water will not get into the connections. 68520
by: Frank H.10/29/2012
great product to us on all trailer electrical connections. Maybe it will keep light bulbs from sticking in sockets as well. 58320
Seals well, and keeps the water OUT of those sensitive electrical connectors. I use this on everything around the boat. 31739
