I've seen a few posts of people asking where the wires are to connect a brake controller. I've torn apart all the trim and carpet on the driver's side on my 2012 Chevy 4500 chassis converted to Sunseeker 2300. I can find no blue or black wire although there are blue and black wires connected to the 7 pin plug at the back of the RV. I followed the wiring from the back to the front hwere they go into the frame and I can't see where they come out. Friends who have installed multiple brake controllers have done the same to no avail.
A mechanic looked at the brake switch and said he would not install the controller because it has a brake switch he has never seen before. I've called Chevy and they say for my VIN the 7 pin connector is not factory. I've called FR who say it came with it and they did not change or move anything. I called two Chevy dealers who say the "wiring diagram for my unit is not on the system." Called dealer I bought it from who said "two wires under the dash" which just simply aren't there. I called a trailer hitch/other install guy who said for the brake switch with 5 wires instead of standard 3 they won't even quote me a price to install it - because they will have hours tracing the wires to determine what controller I need as a regular controller will back feed and blow the computer in the engine !?!?!?!?!
I called a controller company and they said they only provide the controller and can not offer any help on how my vehicle is wired.
Any suggestions? Can someone who has a controller on a Chevy 4500 please post where they found the wires to connect?
Please let me know any help or if anyone has a reputable mechanic near SE Ohio?
Thanks in advance..
