How much wiring do you have to do to make all the seat controls work?
Sorry, I should have included this in the first post.....
Not much to it on the power adjust part of it. That just takes a ground and hot wire in the harness under each front seat. I figured that out with a battery and jumper cables before starting the install. All the control switches are on the seat itself.
I grounded each seat to one of the mounting bolts, and for 12V I used the lumbar wire out of my old harness, which is on a 20 amp breaker in the fuse box, and was already wired in under the drivers seat. I extended it to the passenger side as well.
On the seat, solid black is ground, but if you get the wires reversed hooking them up, its no big deal the switch just works backwards.

The heaters are a different deal, and I don't have them hooked up yet. Here is my best understanding of how they work from what I have read off the web:
Drivers side harness has 5 wires in it: 1 of them is the above mentioned ground and 1 is the above mentioned 12V for the 6 way power. There is 1 other large wire (same dia as the ground and power adjust wire), and it is supposed to power the heaters. The other 2 are small wires. My understanding of them is one is to be powered from an ignition switched 12V source, and its purpose is to switch on a relay (in the seat) which will allow the large 12V heater wire to power the heaters. The other small wire is supposed to be a feed to the other seat to power it's relay.
The passenger seat harness only has 4 wires in it, 3 large and 1 small: It has all the wires from the drivers side, it just don't need the extra relay feed wire, as it doesn't need to send that on to another seat like the drivers side does.
I don't have the heaters working mainly because I just haven't took the time to try. I did run extra wires for the heater, a large 12V source wire to under the dash so that they can be on a different source than the power adjust. Also ran a small relay control wire from under the dash to both seats so that I can power them with a switched on source.
I should also mention that these are 2003 seats, and from reading web info there appears to have been a break at a certain year (don't know which) where the wires are different.
And.....If anyone can't follow this, go back and read it slow.
If I can figure it out, anybody can!!
. I found some blue leather seats that look just like your original ones that you took out, except they are leather, but still not sure if I like them yet. But great job on finding such a good deal on them, and great job on the install. They look awesome in your truck
