Someone hooked up a haul trailer plug on my truck. I want too hook up a standard plug but the color code is different. The u-haul plug use a bloke, white, green and yellow. White should be ground and grin and yell should be turn signals. What is black or am I completely wrong.

The 1999 though early 2003 wiring harness jumper that plugs into the relay block will have a reddish/brown 6-way connector and a tag with the last four digits of the wiring harness part number. Second design 2003-05 may have a white plastic connector with part number 5418 as well.

� The 1999 jumper is/was P/N 12171982 with a pink/purple tag identifier of 1982. This number has been superseded to 15366255, with a pink/purple tag identifier of 6255.

� The 2000 jumper harness is P/N 15366255. The pink/purple tag identifier is 6255.

� The 2001-2002 jumper is P/N 15086884. The orange tag identifier is 6884.

� The 2003-05 jumper is P/N 15085418. The orange tag identifier is 5418.

When transferring the brake controller with the wiring jumper attached from a 2001-2002 vehicle to a 2003-05 vehicle, a change to the jumper harness connector must be performed.

The following information is for the 1999-2002 wiring harnesses.
