Title: Firewall Connector Wiring
Post by: kikkegek on April 09, 2018, 02:44:30 pm

hi Guys, sorry to bring up an old topic. But I am looking for the pin layout of the big firewall connector behind the fusebox of a 1983 6.2 diesel truck (suburban actually) like you guys shared in the previous post.

I cant find that any where. Hope you can help me out
