One thing about cooltech harness... from what I remember reading. If the blinkers/hazards are on and you are stepping on the brakes... the brakes over-ride the blinkers. I did not like that...
Here is my setup:
1. Readybrute Elite with tow bar surge brake indicator on dash of MH
2. Extra Brake wiring for the Jeeps' brake indicator on dash of MH, like the surge brake indicator, it uses power from the MH.
3. Readybrake Breakaway System
4. Mopar Harness... Isolates electrical from Jeep/MH, power is strictly from MH. None of the blinkers/hazard/brakes over-ride each other. No, electrical backfeeding to the Jeep.
5. Curry Baseplate/skidplate.... it is a Jeep after-all.
1. Simple Philosophy, surge brakes, have indication for brakes on tow bar and tow vehicle. Used extra brake light limit switch for the Jeep brake indication light.
2. Mopar harness is behind the grill. No need to mount plugs. cables on mounting plate. Mounting disconnect plugs is not necessary. Curry baseplate has 2 function: Skid plate and baseplate. It also keep the look of the Jeep clean... so, when offroading, you wont risk damaging light harness or breakaway plugs.... it is a jeep afterall.
3. Has emergency cable as well as breakaway system.
4. Easy to hook/unhook.
1. Lots of wire run from the back/front of MH for brake feedback indication.
2. Mopar cable requires, drilling a hole of about @1.5" through the firewall and running the cable inside the plastic R-front wheel well to behind the front grill.
3. When the breakaway system is deployed... you wont have an indication. Unless you have a back-up camera or something else.
4. Installation is labor intensive due to baseplate mounting and cutting and filing for good fitment to the jeep
If you want a nice clean setup... I recommend the setup I have. It is an easy install but labor intensive. If you have the time, its worth the effort.
