Which Wrangler Wiring Kit

[RnG]

Figured I would update the community. I received a 7-6 Blue Ox umbilical cord I ordered from etrailer. It came with a black plastic 6 pin connector for mounting on the Blue Ox baseplate I already mounted. I installed the CoolTech wiring harness to the left rear light, routed the cable through the left frame rail from the rear-most hole to the front-most hole, and wired it to the 6 pin connector screwed to the posts on the baseplate. I checked the operation with my Suburban and all works perfectly. Even the Wrangler front side marker lights light up with the Suburban lights on (I wasn't expecting this). With the (Suburban) turn signal on, and the Wrangler brakes depressed, the Wrangler turn signal does stop blinking since it is over ridden by the brake circuit. I'm OK with this since to me it is more important that a person behind me knows I am braking as opposed to turning. I received the RVi2 brake kit I ordered so plan to try this out this weekend with the RV.

I look at the brake kit as basically for emergency/hard stops. Most of the slowing down to brake for lights and turning will probably not even activate the RVi brake in the brake setting I expect to use. I guess I'll find out.

Hi Gary--I haven't measured, but I'd estimate at least 24" or so. NOTE that my bumper is a Smity Built, and those connectors are welded on the outside and the inside of the steel bumper. Not sure about the Rockhard bumper??

I still want to make one improvement on my setup.. I used large eye bolts for my backup cables--the bolts go through the Smitty Built bumper from underneath, and then through the Jeep factory (steel) bumper itself, with the washers and nuts on the inside of everything. Super strong, but I should have spread them out a little further.. Right now they are centered in the middle of the Jeep bumper and about 12" apart from each other. I don't think that's necessarily a problem, since the two cables connect to the RV less than 6" apart from each other (straddling the RV's hitch receiver), but sometimes I wonder if I should have spread those out a little further? Trouble is... that's a lot of thick steel to drill through!

Rob, my Rockhard bumper has two sets of pre-drilled holes which are further apart and lower than the tabs. I've decided to go with the lower set which are 24 inches apart and keeps my towbar within the 3 to 4 inches drop between the Jeep and motorhome. I'll use the tabs for the safety cables. While they're wider than yours, I don't know if there is any suggested minimum.

Sounds like a nice setup Gary.

I'm taking my whole rig back to the place that installed my M&G braking system. Had a small leak where the airline connects to the RV quick connect. Had that "tightened up" by my local Freightliner shop and now it delivers no air at all. I'm sure it's just a matter of loosening it up, but I also want them to check the M&G itself in the jeep because I had an instance when i was driving in icy conditions and the jeep brakes were frozen in the "on" state. He suspects that there may have been some water in my air line that froze, but I want to have him check it out anyway.
