Open the hood and look past the bottom left corner of the fuel filter (the round grey thing). There is gonna be a rubber plug in the firewall. Pull it out and there will be you access hole.

For the trailer hitch "supplemental cable they tell you to puncture a hole where the hood release cable goes through the fire wall for the wire then seal it up with RTV when your done. Getting the wire through was the hardest part of the whole job :lol: What you can do is look in your fuse panel under the hood and see if you have a fuse for trailer towing, position 10 I think. If so the wire is pink with a purple stripe and goes through the firewall in a large bundle, through the plug and dissappears into the bundle with a zillion other wires. Your going to say "mine dosen't have the trailer towing package" :roll: Neither did mine but the wire and fuse were both there :D

Thanks I'll try that rubber plug.Is that rubber plug the round one directly behind the fuel filter?

Above the bundle that Joe is talking about and on the fire wall, right next to the fender side and on mine partially covered by the seam sealer, is a smaller plug with nothing in it. You can't see it from the front, only under the dash. I used it for my trailer power and ground.

I think every CRD is wired for trailer brakes and that wire is behind that white plastic cover with the big bundel of wires and labled as "brakes" if that is what you are looking for.

Dave.

Is the pink/purple wire from fuse pos 10 terminated behind the verticle white cover or does it go somewhere else? I looked for it but could not locate it more then once :roll:

Joe,

I don't know because I didn't trace it from the fuse box. There is a great "How To" at KJ Country and in it Corwyn has link photos of locating the cover where the wires are located under the dash, of exposing them behind the white plastic bundle and then finding the on labled "BRAKES". It seems to me that this wire is red but it is not a hot wire it is the wire to the rear plug for brakes. I pulled my power for my brake controller and my ground from the battery . My power goes through a 20 amp breaker. I pulled my power and ground through the above mentioned break in the firewall which Corwyn also has great photos of. This followed the manufactures recommendation. I pulled the "brake sense" from the stop light switch up near the steering column and while this is a powered wire it is small and it only sees power when the brake is depressed. Again this was from the manufactures reccommended install.

The wire from the power distribution box is kind of a pale red maybe not pink. I tapped into it under the dash but never was able to figure out where it went to. It's the same color as the wire in the "complementry" cable for power. The wire for the brakes is blue and was also in my "complementry" cable (I don't have the evic that includes the extra wires to the rear. I've been in contact with Corwyn and he was not aware of the fuse position 10 marked trailer. I tapped into it for my brake power but as I said I never found the end of it???

Perhaps someone with a manual that has a wiring diagram could help here. I assumed that the trailer brake wire simply ran to the rear plug and was unfused as the controller is where the fuse should be it seems. Are you perhaps tapping into the vehicle brake light circuit? What is it fused for? Trailer brakes should be fused for 15>20 amps.

I'ver got a FSM on cd and it shows all possible combinations as if they were there. It shows the wire going to the rear but it's not there :?: I've got trailer brakes working properly and 12 volts for the trailer. It just bugs me I can't find the wire that's already there for that purpose :evil:

Well, I am still confused Joe as the only wire that should be there for brakes is the one from Corwyn's pictures and that is red I think and it is behind the white shield. Jeep doesn't provide you a power wire to supply power to the brake controller only the wire from the controller to the hitch.

I am not sure where the factory power for accessory is fused but there is one in my factory hitch setup, wire that is.

Factory power for towing is fuse 10 on the power distribution panel by the battery. The control for the relays for tail lights and trailer power are controled through fuse 25 by the drivers door :P

It's the POWER line I'm looking for that feeds the relays that are in the right rear quarter panel. Without it us without the factory tow package and no evic will not get any tail lights or trailer power. Just signal and brake lights. I ran seperate power lines from the battery to my brake controler.

Also something you have with the tow package is with ignition off there's no 12 volts on your 7 pin plug. Us who add the supplemental cable have a constant power to the trailer on the 7 pin plug. I've since changed that to another circuit that already there that's switched.

Post subject:  the 4 wires on the supplemental harness?
Intstalled the main harness no problems.

...so then I get to the supplemental harness -- directions have four wires/pins being installed into the female coupling in the right rear corner of the Liberty (connector positions 1, 7, 8 and 14). Problem is...there are already wires/pins in those locations. The existing wires in the connector are not the same colour as the ones from the supplemental harness.

I can see that with the supplemental harness wires/pins installed, they would correlate to the four lb, pk/db, rd/bk, br/pk wires that I see in the 1, 7, 8, 14 connector positions of the main harness I just installed, and that threaded up to the front of the vehicle and hooked up, would appropriately power the trailer harness.

Question: Do I remove and tape the existing wires in the existing female connector in order to install the four wire/pins of the supplemental harness?

Thanks to any of the "chosen few" who may have already done this.

I'm puzzled...I would have thought the female connector would have had four empty pin-outs that the supp harness would have just slipped into...I'd hate to remove wires that shouldn't otherwise be removed.

Thanks,
Duey

I am one of the chosen few :( Do you have a EVIC? If so you don't need it. If not then see if you have 12 volts out pin 2 of the 7 pin plug (5 o'clock position), It should require starting the engine (key on). Then turn the lights on and see if you have 12V on pin 3 (11 o'clock position) If you have the voltages listed above you don't need the second cable. Unless your reading the pin numbers wrong? The connector you want is the one that plugs into the trailer harness end that only has one harness coming out. When I did mine it looked as your saying. I looked for empty positions and figured out I was looking at the wrong pins :roll: You may bot be one of the chosen few :lol:

Joe, I am one of the "chosen few" as well...no EVIC, hence my purchase of the supplemental harness. I also looked through the white bin on the LHD kickstep...no blue for a trailer brake, either.

I went ahead and yanked the four wires...I can't believe that there would have been 20A hot 12V going through the dinky little 20ga. wire that the pink/d.blue 12 ga. wire replaced... some pics to follow. Full electrical test tomorrow in the light...

pics coming.

Cheers,
Duey

Post subject:  UPDATE:
The infamour "STEP 10" - just put the wires in like this - drawing makes it look like there are empty slots for the wires:
Image



So here are the four wires/pins from the supplemental harness laid by the connector that the instructions say to insert them into:
Image



A close-up of the connect with the 1, 7, 8 and 14 original wires still in (the fuscia (?) wires to the right and the tan/pink and red on the left:
Image



Here I'm lining the wires up with the female connector in the orientation that "STEP 10" says to insert them into the connector -- seems to make sense as you can see that the blue trailer brake wire and the pink/blue trace 12V hot wires would link up with the male connector's wiring seen on the left:
Image



Having finished doing the deed...two fuscia and the tan/pink trace and solid red are individually taped off, then bunched together.
Image



I did not test whether these original wires had the power that one should expect in the harness assembly...I tested the end result and have 12V (fused) hot in the 7-way connector, and the running lights and turn signals work as well. I haven't hooked up my Tekonsha Voyageur...that'll be tomorrow...so I'll have to wait out on that one.

Did anybody else pull the other 4 wires when they installed a supplemental harness?

Cheers,
Duey

Very strange those positions would have wires in them :roll: But we do have a wire for our non existant lift pump :wink: Others have reported having wires without the evic. Seems like they put on whatever they had on the shelf.

Joe, it was indeed strange! Inquiring minds like mine would love to know what I disconnected, but I'm not worrying too much as I no that the trailer harness has the proper four wires in it now (trl brk, 12V hot, 12V switched, and...well, something else)

I'm just about to install the Tekonsha controller so I'll let you guys know how the final wiring check goes.

Duey
