[QUOTE="iaff284, post: 437018, member: 20764"] Hey all! New member and first post! I have a 1990 YJ that I just finished a 4.0L and AW4 swap in. Everything is up and running and I just have two issue oustanding. First the VSS on the AW4 and wiring harness was a three wire setup. I am using the vss for a 1991 YJ which is a two wire setup. I looked all over online and found info that said I could just use the wh/or signal wire and the blu/Lt blu wires to move from the three wire to the two wire setup. The speedometer works now so the sensor is turning but I am getting a code for no speed sensor detected……anyone know the right way to wire it? Second, the 4wd indicator light won’t work. I have redone the wiring so that the switch on the transfer case connects the ground to turn on the light when the handle is pulled. I can connect the two wires at the switch and the light comes on. I replaced the switch (the old one was bad) and tested it and its good and will turn the light on if I connect the wires and push it in. But it wont work threaded into the housing? Any thoughts???? All help is appreciated!!! [/QUOTE]
