The brake switch at the pedal does have six wires, but none go to the multifunction switch (on the steering column). The white wire with tan tracer goes to the combination flasher to be integrated with the turn signals/hazard lights. The combination flasher is under the dash next to the steering column and has a sixteen pin connector (ten of which have wires).
Hi, the instructions may be confusing. You need to hook the sense wire to the cold side of the stoplight switch--not the stop lamps. The stoplight switch is above the brake pedal. Am I making sense?
With both tail light lenses removed locate the black with yellow wires
and the dark green with brown wires coming out of the brake/tail/turn
signal sockets.
The black with yellow wire will be the running
lights or tail lights and the brown wire from the trailer harness will
attach to it.
The green wire on the trailer harness will be
the right turn signal and will be attached to the passenger side tail
light harness dark green with brown wire.
The yellow wire on the
trailer harness will be the left turn signal and will be attached to
the dark green with brown wire on the drivers side tail light harness.
The
white wire on the trailer harness is the ground wire and will need to
be attached to a good ground. Is it pretty easy to crimp an eyelet onto
the end of the wire and use a self tapping screw to attach it to the
body behind one of the tail light lenses.
Here is a trailer light/wiring article I have done in the past. It has a couple of good tips you may find useful.
This is for a 2003, but trailer wiring is typically standard. Only the AUX and center pin on occasion are wired for different functions:
Center: Back-up Lamps (VT/BK) 1-o'clock: Battery (RD/TN) 3-o'clock: Stop/Right Turn (BK/PK) 5-o'clock: Electric Brake (LB) 7-o'clock: Ground (BK) 9-o'clock: Stop/Left Turn (DG/RD) 11-o'clock: Running Lights (BK/OR)
Get a tester light the type with an alligator clip and a sharp point.
Check each wire for your brake lights,blinkers etc.
i.e. With the blinker light on find the correct wire and splice into it with the corresponding light on the trailer. ( DO NOT CUT THE TRUCKS WIRE)
Remove the covering and twist the plug wires around it and tape or shrink wrap if you can.
Hope this helps
all you need is a cheap continuity tester, any one to help tap on the brakes..7pin is just like the 4 pin w/extra power wire for acc.lites,electric brakes.when you buy the 7pin rec.,comes w/wiring schematic standard to all trailer rec.- you can do it..kev-mn.
If you have a trailer plug installed trace the wires to see if there is a bare spot or broken wire.If no plug then you need to check for bare wire or broken wire from tail lamp assemblys to where the wire plugs into main wireing harness.
