Today on this 2004 Mini Cooper, we're going to install part number BX88267 from Blue Ox. This is their tail light wiring kit for towed vehicles with LED bulbs. First thing were going to do is take a floor wire and we'll route it down towards the front of the vehicle and to the center. We'll run it down below the driver's side head light below the bumper cover and out to the center. Go ahead and open up the panel below the vehicle so we can get better access to the wires that we pushed through. Pull it down across and then route it out to our opening into the grill.
We'll go ahead and pull our wire through and then we'll go ahead and start installing our 4-pole connector. Now, this connector does not come with the kit. This is from part number RN-164-7, RoadMaster's 7 to 4-wire Flexo-Coil Kit. Before we install the connector itself, we'll go ahead and install the hardware to help hold the connector in place. These parts came with a base plate already installed on the vehicle.
These bolts are self-threaded cutting so we'll run them out a few times where we'll do our final assemble. We'll install the screws and then the small brackets, one on each side, and we'll leave them snug but still we can able to move them around. Then we'll go ahead and attach our 4-pole connector. First, we'll disassemble the 4-pole connector and then we'll run our wire through it. On our 4-wire end, we'll separate the wires and strip back the ends, and connect them to our 4-pole connector and then we'll connect our wires to the back side of the connector.
We'll be using this sequence looking at the front of the connector with the set screw on the top. On the left hand side will be number one. Our number one pin will be our left turn and stop. Now, it will be our yellow wire. We'll loosen up the set screws and then install the wires.
Down below on the left hand side will be number two and that will be the ground. That will be our white wire. Back on top, the number three, that will be our right turn and stop and that it will be our green wire. Number four will be our tail light and that will be our brown wire, and then we'll reassemble the connector. It also may be a good idea to wrap some electrical tape around the wire behind the connector and then we'll go attach the connector to the brackets. Now, continue routing the 4-pole wire towards the back of the vehicle. We're going to route it around the engine over towards the top and then through the firewall. We'll use some zip ties to keep the wires together and out of the way. There is a small panel in front of the brake fluid reservoir then we have to run our wire through. We'll pull up on the seal and a small section with a rubber seal on it. We'll go ahead and push that out of the way and then push our wire on top of that, and then we'll reinstall the seal. Now running it to the firewall, there's a large round grommet right behind it. First off, we'll go ahead and show you with the screwdriver and then we'll poke a hole through it. Now, this is easier done from the inside. Now to pull our wires through first, we're going to run a piece of airline tubing to the grommet. This could also be in a stiff piece of wire to help pull our 4-pole wire back through. With the red tubing through the grommet, we'll take some electrical tape and connect the 4-pole wires to the red tubing. We'll go ahead and pull it through the grommet and we'll take up all the slack and then we'll go ahead and route it over to the left side above the components to make sure we stay away from the steering components underneath the dash. Then basically, we can go ahead and start taking the wire and routing it towards the back. We're going to tuck it underneath the plastic panels. Up towards the front, we'll remove the fuse panel cover so we could get access to the wire and pull it through behind it then we'll going to run it at the back side so we can hide it behind the rubber seal along the edge. We'll run it pass on the length of the door and going towards the back. We'll keep it underneath the plastic until we get to the back seat and then we'll go ahead and tuck it between the plastic and the back seat as far as we can, then push it underneath the hinge for the back seat and then we'll work it behind the plastic there. Now, our wire is back by the tail lights. We'll go ahead and remove the tail lights. There's one that we have to remove and then there are two clips on the inside. You have to feel for the clips on the inside. You really can't see them from the outside. This may help to remove the light bulbs as well to get easier access to the tabs. I'm going to release the tabs. We'll go ahead and push the light out. With the light out, we can show you the tabs that we're talking about now. All right, now we have to install our LED lights. We have to drill a 9/16 hole on the back side of the light. Now, we're going to try to keep it about an inch away where the location of the original tail light bulb is. When we drill it out, we'll use a pilot hole first, a 1/4-inch bit, and then follow it up with a 9/16. Now, use light pressure so you dont go from the inside and crack the housing on the outside. Now, we'll go ahead and install the socket. Push it into place until it clicks in. It may help to twist it a little bit as you install it. You should hear a small click once fully installed and then we'll go ahead and run some sealant around to help hold it in place as well and protect it. Now, we can go ahead and reinstall the light. We'll push it back into place and make sure we dont disturb the new wire we just installed. We're done with our light for the driver's side. We'll go ahead and start connecting our wires. First off, we'll start with a white ground wire. We'll take our 4-pole wire. We'll peel back the ground and we'll cut it in half and then install a ring terminal. We'll add that to the factory ground that's located behind the plastic panel. The rest of the white wire going towards the back, we'll go to our white wire off our socket. We'll connect those two together using a butt connector. Now, we have a brown and a black wire leftover. Our brown wire from the 4-pole wire will connect to the brown wire as well. We'll pull away our brown wire. We'll cut it in half. We'll twist those two together and install to the end of the butt connector and on the other end of that butt connector will connect to our brown wire from our new socket. Now, we need to do this because our brown wire will continue on over to the other side. Now, the black wire is going to be our turn signal circuit. Since it sits on our driver's side, we'll connect that to the yellow wire and we'll use the butt connector and we can direct connection. Now, we'll snip off the rest of our yellow wire since we won't need it on the other side. We'll take the remaining wires and run them over to the passenger's side. To do this, we'll remove the threshold and run the wires underneath it. To remove the threshold, we'll take out these three pushpin fasteners and pry the threshold up. We'll go ahead and remove the tail light and install the socket on that side as well, repeating the same thing we did on the driver's side. Once it's reinstalled, we'll go ahead and connect our wires. At the passenger's side, we'll take the excess white wire. Strip back the ends and add a butt connector to one end. We'll then connect it to the white wire on the LED light. On the other end of the excess wire, we'll strip back and add a ring terminal which will be connected to the factory ground point. Our ground will go to the brown wire and our green wire will go to the black wire. We'll now reassemble the interior. With all our connections made, we'll go ahead and try it out. Now, our brown wire will be our running light circuit so we'll check that, and then our yellow wire will be our left turn signal. We'll go ahead and check that. Green wire will be our right turn signal and we'll check that. With that, that will finish it for our install of part number BX88267 from Blue Ox, on our 2004 Mini Cooper.

Just what I needed to replace my old cracking original cable. etrailer is always my first stop for my RV and Trailer needs.
This Roadmaster cable is the one I needed and it is OEM so built well. My 1st one lasted 16 years, still works but showing wear finally so I decided to replace it. Good solid Roadmaster cable with every needed part for a new installation inside a strong package. I had ordered the wrong one (Blue Ox) and Etrailer made it easy to return and order the correct one. Etrailer is a pleasure to work with. This one is well built and a few dollars cheaper than the Blue Ox. I am happy!
This is a direct replacement part, so I'm well familiar with Roadmaster equipment. I haven't tried it yet and I don't expect any problems. The part was easy to order online and delivered when promised.
Karl - 02/14/2020I ordered this item to replace a similar harness that had been stolen out of my truck, but was very disappointed to discover that the 7-pin plug would not engage properly with the OEM receptacle on my Dodge truck with factory hitch and tow package! The spring loaded cover on the receptacle would not engage the retaining tang on the plug, and when I finally forced the plug in far enough for it to engage, the left rear turn signal and brake light on the trailer did not work. The plug on the previous harness fit perfectly, so the location of some of the 7 female slots on the Roadmaster plug was evidently not correct. I paid a premium to return it ASAP via UPS expedited shipment over the Memorial Day weekend; I eventually received a warranty replacement 17 days later. At least the 7 pin plug on replacement harness does fit correctly. I will admit that the metal 4 pin plug and receptacle on the trailer end of the Roadmaster harness are much better quality than the cheap plastic parts on the original harness. I would recommend that anyone buying one of these Roadmaster cables first check the fit of the 7 pin plug with your hitch receptacle before bothering to hook up the 4 pin receptacle for the trailer, in case you have to return it!
I recently purchased a Blue Ox tow bar, towed vehicle brake system and three wiring harnesses for towing my Jeep Liberty with our motorhome. etrailer.com was my first choice for the purchase for these items worth almost two thousand dollars. Even though these prices were set by the manufacturer, I knew I could trust these folks. Their salesmen, (in this case Wayne H.), are more than just order-takers. They know what they are selling and are a good source of information on a variety of related products. When Wayne wasn't available for follow-up discussions, the operator took my cell number. Surprisingly, Wayne got back with me right away and supplied me with his direct line in case I had any questions. I've had experience with others dealers who don't get back for hours if at all. Bottom line: etrailer.com will continue to be my first choice for RV and other related items.
I've only used this item for a week so I cant say if it maintains its coil. The only thing I'm not happy about is the 4 prong male / female end. It doesn't lock in good enough in my opinion. I feel with a slight tug or bouncing movement it will dislodge itself and drag on the ground. So what I do is wrap a velcro strap around it to make sure that does not happen. Should one have to do this? You decide. I did like the attach method of the wires inside the female connector. Easy and solid
After having my boat trailer powder-coated blue, this was a good match for the trailer. And I like being able to disconnect the entire harness.
Michael - 11/13/2018I needed to order a replacement connector and a Blue Ox tow bar. The website was extremely helpful, but I had some questions and called. Kevin helped be out on the order, getting me just what I needed. I had the items before the weekend, extremely impressive! The tow bar and electric connector are excellent products and a great way to tow my jeep behind our Nexus RV.
Was looking for a 7 pin to 4 pin Flexo Coil Kit. Found it on line at etrailer at ma reduced price I was willing to pay. When I checked with my local RV dealer, He said I needed to buy from e trailer. Their price was below his cost..
I am customizing my Jeep Wrangler to tow behind my motorhome. This coiled electrical plug was exactly what I ordered and needed. Excellent customer service always! I'm grateful to have etrailer to help me when I need it. I will always go to etrailer first!
Proper product, received in good condition when I was expecting it. etrailer.com performed as they indicated they would. I'll certainly return to shop when necessary.

This part solved my problem and after simply plugging the cable in, all lights worked perfectly. Thanks for the prompt shipping and delivery, it arrived in time for our holiday travels.
great product at a very reasonable price delivered on time.
Great website. I used e trailer once before with great results. I purchased a new RV and needed to replace a 4-WIRE to 4-WIRE cable with a 7-WIRE to 4-WIRE. GOOGLE sent me to e trailer. Their price was $25 less than three places that I visited in person, even with their shipping.
Great product!
The products are excellent, but the shipping could be faster.
Just what we wanted. Fast delivery. Great service.
