Does anyone have a diagram of where each connector on the transfer case wiring harness goes. Theres a circle connector and 2 end connectors im not sure where they plug into. Picture of it would be nice.

 

What year?

 

Look into a FSM for the plugs you need locations for. As to the years of the transfercases some older ones were pretty much mechanical and had little or no plugs and as the years came closer to 2001 those things increased so you may have a transfercase which does not require any electrical connections at all.

 

the transfer case is out of a 96 cherokee and my vehicle is a 92

 

Can someone atleast tell me the circle 4 wire plug is thats at the end of the transfer case wiring harness.

 

Have you a FSM for the 96 JC? If so check the wiring diagram to see where those wires go.

 

no i dont. I have it for a 92

 

I have a feeling that the "circle 4 wire plug" is for vacuum engagement of the front axle on some models...

 

You may be right 89xj as I went to crawl under mine to check (bad memory) and saw nothing like that but I have a 242 and they never had disco axles.

 

Well my transfer case doesnt have a plug for it.

 

I thought maybe it was an o2 sensor.

 

if im on the same page, it is for the spedo sensor, if thats the case swap your speedo gears as well

 

The red circle is the connector I was talking about. The arrow is the speed sensor I believe.

 

your correct i think those wire tell the ecm whether your in high, low or neutral

 

yea, my '91 had those w/ the vac activated front axle. If I recall, some of the wires off the sw went to the front axle vac switch and some went 'upstairs, probably idiot light, possibly PCM.
