This post describes what one of my good friends calls "OEMitis" ... I did all the in cab wiring today, which was done to make it look as if the factory did it.
First connection (for the brake controller) - stop light switch.
Before
After
Rear harness firewall connector - after shot, connections for turn, marker and reverse
Main harness reloomed - new trailer harness connector is the 6 connector black right in front of the gas pedal
Thru-bulkhead connector carrying lights (4 wires), ground/power/ brake feed from brake controller (3 wires)
Used a factory marked drill point and knockout in the insulation to install it, just like they meant it to be there
Bulkhead connector with mating harness connector attached
And the new fender mounted junction box, which connects the rear trailer harness to the bulkhead connector and houses the 2 self-resetting circuit breakers (30A for brake controller and 20A accessory feed to the trailer)
The loose black and white wires are power and ground, I ordered a special jacketed cable for that purpose but UPS is still trying to find it...
Tomorrow the hitch goes on, as will the rear trailer connector, then an oil change and fuel sender and first trailer towing tomorrow afternoon!
