ok i just did a cab swap from a 97 to a 01 cab and some things are different but for the most part its all the same including the 4x4 but for some reason it does not work? i took the whole wiring harness out of the old cab and it all worked before i started this project but now the switch is getting no juice? can anyone help me figure out what the problem is?

 

It sound like you accidently cut a wire some where trace them

 

i dont want to but i think your right the thing is the only way to trace back the wire is to take the whole dash out and i already did that once but if i have to i will do it again. but i just looked at it again today and if this may be a clue i have juice at the vaccume solinoids? and at the fuse and the fuse is fine??

 

Is it at all grounded it should blow the fuse

 

GOT IT!!!! while i was cleaning up all the junk from my old cab and i found a little black box that was still on the old dash so i took it off found a plug that wasnt used for anything and bam! engaged right away!
