Imp558 Posted February 19, 2018 Report Share Posted February 19, 2018 No, it's the orange wire that's serial data. It's probably whacked at c100 then. Check out that thread, it's not hard to pull pins from a connector like c100. If you cut one off a donor car with a foot of wire you'll have donor pigtailed pins. That type of connector was used on a lot of cars, not just the W. Quote Link to comment Share on other sites More sharing options...
crazyd Posted February 19, 2018 Author Report Share Posted February 19, 2018 Unless I'm reading your charts in the pin thread wrong, it looks like it's green on the engine side of C100 and orange on the other side. Not sure why they'd change it Quote Link to comment Share on other sites More sharing options...

Not sure why they'd change it Just grainy images, it's ORN, not GRN. on an OBD-II Green or violet would be typical of Serial Data class II. on a 1992 Serial Data is Orange, Tan a year or 2 later. I'm editing the early part of that thread for C100 ppin extraction in like 10 minutes Edited February 19, 2018 by Imp558 Quote Link to comment Share on other sites More sharing options...
Imp558 Posted February 19, 2018 Report Share Posted February 19, 2018 It says not to backprobe it, which I assume is so the weatherpack seal isn't damaged. Just disconnect the battery and unplug the ECM. It's safe to test continuity. Quote Link to comment Share on other sites More sharing options...
