daking Posted March 24, 2015 Share Posted March 24, 2015 I need some help identifying some connectors under the dash. Its a transplanted harness from a 1991 XJ into an 87 MJ. Black connector, 4 pin (heavy gauge wire) yellow plug, coming from steering column. White 2 pin connector (Wh/Bk goes to fuse panel, Wh/Pk goes to break switch, va an adapter) Black connector, 4 hole, with 3 wires Blue connector (fits the break switch too, but is not connected) And if anyone knows, what is the "red" relay? Image Not Found Thanks! Link to comment Share on other sites More sharing options...
Rockfrog Posted March 24, 2015 Share Posted March 24, 2015 Ok, let me have a quick go at this ... Mid right of picture, black connector, 4 wires - receptacle for headlight delay timer. Translucent connector upper right - emissions timer. Yellow plug with circuit board type connector - cruise control. White 2 pin between fuse panel and break switch - again for cruise control (shuts off cruise when you tap breaks). The rest I don't know off hand, need to sit in front (under my dash and it's a 3hr boat ride, and a 4hr crew bus ride away). Link to comment Share on other sites More sharing options...
daking Posted March 24, 2015 Author Share Posted March 24, 2015 Awesome, thanks for your info. I suppose I can remove the cruse control wires, Not going to have it. I wonder if the blue connector is related to cruse control..? I was thinking its for tow package though. That blue connector fits the break switch too, same pin and size. I need to do some research on the head light dimmer. I'm assuming it leaves the head lights on for a set time after key off? Link to comment Share on other sites More sharing options...
Rockfrog Posted March 24, 2015 Share Posted March 24, 2015 Yeah, I pulled one from a 92 xj and popped it in my 88. Lights off after key - headlights stay on for a period of time. Lights of before key off - lights go off as normal. Link to comment Share on other sites More sharing options...
schardein Posted March 25, 2015 Share Posted March 25, 2015 The red relay is for the rear window defrost in rear hatch of XJ. Works like a regular relay but goes off after set time. Replacement parts stores list them for $$$$$ but they never seem to go bad. Link to comment Share on other sites More sharing options...

Replacement parts stores list them for $$$$$ but they never seem to go bad. That's good to know. I'll save that relay, may find a use for it in the future. Like electric fan delay, or light delay.
