took out my old shot 914 seats, and am installing some 911/993 seats tight fit but will work well.
I need some advice regarding the wiring, if anyone out there has attemted similar?
with the pig-tails hooked up under the seat the other ends have 3 wires(i assume these would have gone to the fuse/relay bank in a 993). These 3 wires are : red, black and brown. I was connect the red(Positive?) to a new fuse/breaker which in turn would go to the battery(+) , then the negative direct to the battery(-)(black?), but is the brown/tan a ground or ???
can't find a wiring schematic or discussion showing what is what on that model, any help would be appreciated! (IMG:style_emoticons/default/confused24.gif)

Do you also have the switches/controls to go with the seats? If not you'll be doing some creative work to rig something custom up.

Here is the wiring for the 8 pin connector on the body harness that connector in your picture plugs into:
Pins 1, 3, 5, & 7 all connect to Term 31 (ground) with brown wire(s)
Pins 4, 6, & 8 all connect to Term 30 (Battery, hot at all times) with Red wire(s) 30amp circuit for each seat
Pin 2 connects to Term X (hot key on and engine running, off while cranking) with Violet wire. 25amp circuit for both seats

All 8 of these wires supply power and ground to all the different power seats.
The wiring of each seat varies depending on how many adjustments it has and whether it is heated or not, etc, etc....
All the diagrams I looked at only showed Red and Brown wires on the seats themselves, no black wires. All the red wires go to Term 30 or Term X, brown are Term 31.

This is from the factory diagram for a 97 993 but all the others I looked at appeared the same.

I would suspect you black wire needs to go to power but I would figure out which pin of the body harness connector it would have connected to and verify before melting something.
