    Hey all, I have these plugs sitting unplugged in the front of my bay on either side. This is the plug to the headlight control relay, right? Where is that supposed to be mounted originally? I think both are missing, no clue why.

    Hey everyone, My 89 Turbo yard find is coming along really nicely. After checking codes, I’ve got 31 among some others. Assuming wiring is good, is it a good idea to go ahead and grab another AFM? Thanks. I’m planning on posting a build and progress thread for my hidden gem soon.

    Hey all, Can someone give me some info on this ECU that was just randomly sitting in my car? My car (89 turbo m/t) has an ECU in it, but this one was just sitting there. I assume this is for a turbo a/t car based on the label? Any information is welcome.
