Ok. I bought a brake controller and wiring harness today. All the posts I have searched say be careful not to use the older harness as it's wired different. Mine does not list a year on it so I don't know if it's older or not. What sequence do the wires go in on the correct plug?

Did your SS come with the tow package :confused: . If so you should have got the harness with the truck, and the wiring is labled on the harness.

ok guys, here you go:

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 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 This number has been superseded to 15366255, with a pink/purple tag identifier of 6255.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 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 vehicle, a change to the jumper harness connector must be performed.

Your best bet go on ebay and buy the harness for your truck. I had to buy one for my truck it plugged under the dash into the box and I was done. I didn't use the factory or they gave me! Only cost 15 buck ad shipping was super fast!
