m2bandit Posted June 25, 2019 Share Posted June 25, 2019 I'm trying to put AC in my 88 MJ I have the C100 diagram for my parts jeep (89 xj) and I want to make sure it's compatible. I have the 88 mj electrical trouble shooting manual but it doesn't show the c100 connections. Link to comment Share on other sites More sharing options...

m2bandit Posted June 25, 2019 Author Share Posted June 25, 2019 C100, the bulkhead connector. The large one that connects engine compartment wiring to interior wiring. Link to comment Share on other sites More sharing options...

But page 8 of the '88 electrical manual shows the fuse panel wiring, and the C100 connection points are called out on that diagram. Link to comment Share on other sites More sharing options...
Ωhm Posted June 26, 2019 Share Posted June 26, 2019 True, but more than just page 8 goes through C100. You'd need to go through each page and find all C100 callouts. Didn't in 89 and above they had a connector end view with table of cavity numbers and circuit names. I thought that was what he was looking for.

Great so I can just slap the 89 engine side in there and I'm good to go? 2 hours ago, Ωhm said: True, but more than just page 8 goes through C100.

DirtyComanche Posted June 26, 2019 Share Posted June 26, 2019 Check the other end of that harness, there's a change in the connectors sometime around there, they went away from the GM Weatherpacks to Chrysler connectors. It's obvious if it's a problem. Link to comment Share on other sites More sharing options...

Jeep Driver Posted June 26, 2019 Share Posted June 26, 2019 Have you looked at your '88 to see if the wiring for AC is present or are you just assuming that it is not? AC relay should be present (wiring). Clutch wire should be there. AC pressure switch terminal should be there. As far as I know that's about it.

I just confirmed there's no wiring at all for the AC and no AC relay. Link to comment Share on other sites More sharing options...

m2bandit Posted July 7, 2019 Author Share Posted July 7, 2019 yeah I thought the same Just wanted to correct green and black terminates 6" after c100 so a small portion is there. It's not on the interior c100 so you'd have to get those connectors and add it. Also the Heater control wiring is a different style plug. Non AC is a flat blade of plugs with only 2 wires Ac is a square connector with 4-5. Link to comment Share on other sites More sharing options...
