I pulled seats from an 86 126 (nice seats) gasoline clunker to put into my 82 300SD. As I recall my SD has connectors at the seats and I chased the wiring as far as I could at pik-n-pull and did not find connectors so I cut the wiring as far from the front seats as I could.

It's been a while since I had a good close up look at the underside of the seats in the 300SD and I would like to know as much as I can about the newer seats before i start pulling and splicing

any suggestion where to start troubleshooting?
if I had a starting point I could probably figure out the rest

BUNDLE ONE:
HEAVY GAUGE
red with white bands black stripe
