Electrical Connectors, under dash

[daking]

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?

Thanks!

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).

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?

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.

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.

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.
