Hi Dave,

Funny you should mention this... I just installed a heated seat harness into
my 1983 ur-quattro last night. I have had it in a box for a year and finally
got
it installed so I can have a warm back at steamboat this weekend. Not
exactly 
the same as a 200 but similar enough.

I started with seats which already had the heating elements in them. I
believe
my harness came from a 1986 5000 series car, the relays were dated 12/85.
I got the my heated seat harness from Chris Semple, he extractaed it from a
car that was being crushed, it included the wiring to each seat with 6 pin 
connectors, relay bases and relays. Chris cut the wires going to the 5000
control switches as I was using a connector and control switch from a 4000 
quattro. With the wiring diagrams in hand and a pile of but splice
connectors,
I connected the switch to the relays. Once this was done, all you need to do
is
hook up the grounds, 30 power(ran special wire from the battery, fused of 
course) and 15 power(found empty terminal on the fuse box). The 6 pin
connectors at the seat plug in. Surprisingly the wires from the 2 different
cars
had the same coloring, so it was easy to trace it out. After a test hookup,
I
lifted the carpet and popped out the seats and installed the harness. 
Everything works great and I had a warm seat on the way to work this 
morning. Also, before I hooked up the harness I ohmed out the heating 
elements in the seats to make sure that they would work and the all showed 
1.1-1.3 ohms.
