I ran into the same problem and solved it. To replace the fuel pump I had to remove the bed since the fuel tank is under it. I had to disconnect the tail light wires including the ground wires. One side had 1 grounding wire and the other had 2 grounding wires. After a month of messing around with fuses and sensors I found out that one of the (Two ground wires) next to the left tail light was actually the (Fuel pump ground wire). So if you don't know which one I am talking about, make sure you connect ALL the tail light wires and plugs before cranking up the engine. This was my luck with the s10 2001 and good luck to you :)

Right tail light.From there you can get all signals you need such as indicators,park light,brake lights and reverce lights

Well try checking the stop light switch.It is located under the dash. Just follow the brake peddel arm up and you should see it.It has two wires and if you pull out the connecter and jumper the terminals in the connecter .The brake lights should come on,if they don't then try replacing your missing fuse.15 amp will do.

Left indicator - Yellow to Black/White
Right Indicator - Green to Black/Green
Left Tail - Black to Grey/Black
Right Tail - Brown to Grey/Red
Fog - Blue to Grey/White
Brake - Red to Black/Red
Earth - White to Brown or Body earth above/behind Left hand Light

the best way to wire it is to get a tail gate board off a trailer and plug it in to the towbar then wire red to stop n tail lights green or yellow to the earth what other orange or brown to indicator sum wires may differ in colur wat colour wires do u have on the towbar

Hey Bryan

I've got them for Six and Four wire plugs

Six wire plugs:

Horse, stock or utility trailers:
White = Ground - GD
Yellow = Left turn/Brake -LT
Green = Right turn Brake -RT
Brown = Tail and clearance lights - TM
Red or Black (not both) = Battery, aux power - A
Blue = Electric Brakes - S

Recreational Vehicle: (color, use, plug mark)
White = Ground - GD
Yellow = Not used -
Brown = Right turn Brake - RT
Green = Tail and clearance lights -TM
Black = Battery, aux power - A
Red = Left turn/Brake - LT
Blue = Electric Brakes - S


Four wire plugs:
White = Ground
Yellow = Left turn/Brake
Green = Right turn Brake
Brown = Tail and clearance lights


Ground should be 10ga.
Others 14 ga

Best regards
Mike

change spark plug wires and check corrosion in the distributor coil
