I'm not at a home, but will do my best with the pictures that I posted.

Starting at the beginning - I bought a 360W/12V power supply. It should be plenty! This is the silver metal piece in the pictures will all the screw terminals. I took a standard 'printer' cable, cut off the female end, stripped back the wires and screwed them into the power supply as shown in the picture. Live/Neutral/Ground.

Once this is done and plugged in, the power supply produces 12v-ish. I put a volt meter across a pair of the outputs and then turned a small 'pot' or adjustment to dial it into 12.0V or as close as it would get.

I then took another 3 conductor cable and connected one wire to a +, another to ground and left the third for use later.

There are 5 different wires that need to be tied to the ground:

• 3 heavy wires from one plug black w/grey
• 1 thinner from the other plug black again
• 1 from the switchpack

In the picture with the screw driver, you'll see one connection that is wrapped in black heat-shrink tubing. Under that heatshrink there is a solder joint with the 3 thick and 1 thin black going in one side and a yellow/green from the other. That yellow/green is going to ground of the power supply.

There are 3(?) wires that need to tie to the +12V. In that same picture with the screw driver, you'll see another connection wrapped in red heat shrink tubing. You can sorta see the colors or read them from earlier in the thread. It's 2 power lines and one green/white 'logic feed line'.

I tied the switch pack in like this:
Black (ground) went directly to the power supply.
Red (12v+) went directly to the power supply
White (LIM aka signal) line went to the 3rd wire in the PS -> Seat wire, which happened to be brown in my case.

The brown line went to the 'LIM' line on the plug. I don't recall the color off hand. In that same picture I'm jumpering it there with a temp purple wire which I later pulled after testing and soldered it directly.

Does this help?

 

So now im on my car and maked some pictures
of connectors and switch controller box.
