Ok So I am swapping in a 4.o and an aw4 out of an xj into my TJ...I have seen the write ups on the aw4 install, but can anyone think of any reason other than it being a PITA of why I couldnt take the complete wiring harness from a 99 xj and put it in my 99 TJ....I know it would be a little longer, but I was looking at the dash and everything is identical...
