Video Transcript for Blue Ox Tail Light Wiring Kit for Towed Vehicles Installation - 2004 Mini Cooper

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.

I like how easy it was to install and the fact you don't have to cut into the cars wiring harness. What it lacks is brightness. The LED's just aren't doing the job. I'm looking at putting bigger taillight LED's to replace the puny stock LED's. The stock LED's are truly a safety hazard. If Blue Ox has fixed that issue it would get an 8 star on a five star scale. 281007

Product was as ordered, at first I didn't think the Red LEDs would be bright enough inside a Red Lens but they work fine. I had concerns about them and emailed on a Sunday and was surprised that I got a response that afternoon. 293748

Your products have been perfect, good fits and quality products. The towing base plate for my ford Fiesta fit with little modification and the ability to use standard tools. The instructions were right on. The tail light wiring kit also was easy and works great. Shipping was fast and delivery arrived as indicated. I will continue to do business with you. 287976

These are terrible. They were properly installed, instructions never stated that the bulbs themselves are polarity sensitive; one was shipped in its socket backwards. Had to completely pull apart post installation to discover this problem. After working out that issue, I then find that cannot see them in the day light at all. Not direct sun light, that's obviously a no-go and even worse, I mean just plain ole day light, they absolutely cannot be seen. They barely provide a fleck of light within the tail lamp housing when lit full-bright in brake or turn-signal mode. I was also not happy to discover that they were not set-up as separate turn/brake lamp and parking light wires. Instead, they use some voltage cutting resistor in-line on a single input wire, which was a cheap shortcut to provide something such as a proper hi-lo dual brightness LED module. The socket used is for your typical bi-pin type 194 marker/courtesy light. Stay away from these until they come out with something either 3 times the size of the leds, brightness and wiring of a real 3157 tail lamp LED module, or increase the included bulb to a 3 row module. These mini LEDs are for courtesy/map/marker lamp use, not for lighting a full tail lamp housing. They are inadequate as-is. You can buy these exact LED 194 replacements by the dozen (yes, 12 LED modules) for under $10. The lumen output of one of these at full brightness is only 40 lumen. That's worse than a nightlight bulb (310 lumens), or for direct comparison to your typical 3157 tail lamp bulb such as in my vehicle, a 3157 bulb outputs >400 lumens on the bright filament, and ~200 lumen on the lower for parking lamp. How they figured 40 lumen would be nearly enough is beyond me, and just plain poor product design and research. Now that I've had to pull them out, I'm left with two destroyed tail lamp housings (having been drilled out) off my brand new vehicle I bought last month with <500 miles on it. 62263


Ask the Experts about this Blue Ox Tow Bar Wiring
Do you have a question about this Tow Bar Wiring?

  • Flat-Tow Wiring Harness and Supplemental Braking System for a 2016 Jeep Cherokee
  • I do have options for you but neither the Roadmaster Tail Light Wiring Kit part # RM-155 or the Blue Ox Tail Light Wiring Kit part # BX88267 will fit your 2016 Jeep Cherokee as there is not enough room inside the tail light housing for the new bulbs. Instead, I recommend the Hopkins Custom Tail Light Wiring Kit for Towed Vehicles part # HM56208 as it is a completely plug and play kit that does not require you to cut any wires or the tail light housing. There won't be any issues using...

  • Will the Blue Ox Tail Light Wiring Kit # BX88267 Act as Brake Lights
  • Yes, the Blue Ox Tail Light Wiring Kit # BX88267 gives you brake, running, and turn signals. I have attached a review video and an installation video for you to reference as well.

  • Is Replacement LED Bulb Available for the Blue OX Tail Light Wiring Kit
  • I reached out to my contact at Blue Ox who said that unfortunately the LED lights are not removable from the harnesses in the Wiring Kit # BX88267 so you would unfortunately need to replace the whole kit. Instead of replacing your whole kit I recommend just swapping out the Blue Ox lights with the Replacement LED Bulbs and Sockets # RM-152-2 from Roadmaster. This prevents you from having to run more wiring or perform further installation on your 2018 Ford F-150.

  • Do the Turn/Brake Signals on the Wiring Kit # BX88267 Need to be Separated for a 2004 Mini Cooper
  • I am a little bit confused as to what you are wanting to do. The Blue Ox Tail Light Wiring Kit # BX88267 that you mentioned uses its own bulb that works both as the brake and turning signals. It completely bypasses the wiring on your 2004 Mini Cooper and directly connects to the motorhome for signal source. If you check out the linked installation video you can see our team install this kit as well as the Flexo-Coil Kit # RM-164-7 for flat towed wiring.

  • Can the LED Bulb and Socket Kit # BX88267 be Installed on a 2009 Subaru Forester for Flat Towing
  • We do have an LED wiring kit just like the Kit # BX8869 that you referenced. It is found as part # BX88267 on our site. You can use the LED kit if your 2009 Subaru Forester does not have LED tail lights and if each tail light housing has enough room for an extra bulb and socket. It could be that there is no room for an extra bulb and socket which would be why the Roadmaster Kit # RM-152-LED isn't confirmed to fit. If you do have LED tail lights (or you don't have enough room for...

This kit includes a the diodes to protect your wiring as well as give you a simple and clean installation. It also comes with the wiring to connect to your motorhome.
