Hey Aussie, 

 

From a visual inspection alone it looks like the IAT sensor...

 

If you have the sensor, see if it will plug in.

 

Better yet, If you are far enough along in the wiring to give the ECU power, you can probe it and it should give you 5v if it is the IAT (IDK if this is true for RENIX)

From your previous posts it seems like knowing what goes where with the wiring is giving you some grief. I'll try and find an engine bay wiring harness schematic for you if you let me know the wiring harness / engine year :)

Just a quick note this plug is in loom that run on the bottom rail behind the bumper 

Thanks

Are those fusible links on that harness? If so, should be the Engine Harness. Could be Radiator Temperature SW for cooling fan control (A/C equipped).

Is it for fog lamps?

[Aussiemj]

Yes it engine harness that run across the bottom radiator rail . I will check colour for fog light 

Thanks

There should be two similar connectors, one on each side.

Quite certain that it is the ambient temp sensor for the overhead console in a XJ. Unless there are 2 of them one on each side for the fog lights.

 

To my knowledge both XJ's and MJ's got the same harness from the bulkhead forward but the MJ got some stuff removed from the cab side. For example XJ's got a low washer light and overhead console with temp but those wires are missing on the MJ. 

 

Here is some info on that plug but no pics.

Maybe @Automan2164 still has the pic.
