I am in the process of installing the factory option power steps. The
problem is that the wiring color code doesn't jive with the recommendation
in the directions. I have the Factory CD documentation for both the '03
trucks and the '04 trucks. My truck in an early '04. I assume the connection
for the step motors is the door ajar driver connection on page 8w-44-3. Am I
correct? Or should I connect them to the door sense switch? I am installing
steps on the front doors only. There is one wire from each step. The
directions are to splice them to different wires on the same connector, but
the colors do not match. Any help would be appreciated.
I'm assuming you have either an SLT or a Laramie, which means you need to
follow the "except base" portion, which is shown in better detail on
8W-40-7, which shows that you want to connect to the purple wire, coming off
pin #1 of the lock motor connector. This is a ground sense, so make sure
your wiring from your powersteps expects to see ground on it's signal wire,
and not +12V.
The passenger side wiring is shown on 8W-40-6, and here you want the
These pages are from the '04 FSM.
You were spot on. The confusion was the result of the directions that were
included. They were for a 2001 truck Your directions brought me directly to
the C3 connector. The only determination I had to make was which sense wire
was for what side. The drawing is well marked. The steps were not. In fact
the steps required sensing of voltage and earth, as the motor has to run in
both directions. They actually work very well. Thanks again.
