Zebvance Posted February 10, 2015 Share Posted February 10, 2015 Shortly after buying my Comanche 3 years ago I found out my 4x4 light didn't work. Not to long after that I found out that the PO had converted my truck from 2wd to 4wd. SO that would explain why the light indicator doesn't work probably. Well I would like to get it working and I need a parts list of what I need to do so. I'm guessing I just don't have the stock wiring/harness to make it work. Could someone help me figure out what I need to do to make this happen. A wiring schmatic. list of sensors, diagrams, anything will help. I want to make it OEM.

I want to make it OEM. is the axle a vacuum disconnect axle (CAD) ? I had the same problem and just re ran the vacuum lines, my light is triggered by a sensor in the vacuum lines!

No the front axle is out of a 2001 xj, which is currently bent and being swapped with a 98 tj d30 Link to comment Share on other sites More sharing options...

Incommando Posted February 11, 2015 Share Posted February 11, 2015 The later 231 (assuming that is what was used in the swap) uses a sensor/switch on top of the t-case to activate the 4wd light. I don't know the wiring for the in-dash light but you can start at that switch to see which position sends the signal. Wire power in from keyed source and trace wire from dash light to connect to the other pole on the switch. Link to comment Share on other sites More sharing options...
Zebvance Posted February 11, 2015 Author Share Posted February 11, 2015 Last time I looked at the transfer case It was listed as a np231J. I think I remember thinking it was dated 91. I would look but right now the truck is in the shop having the rear main seal, oil pan, and oil pan gasket replaced. Link to comment Share on other sites More sharing options...
