Question about 1991 Jeep Cherokee Limited
Swap from 1991 jeep wrangler 2.5 engine with standard transmission 4x4 to a 4.0 with auto transmission 4x4 complete with transfer case including computor and wiring harness from a 1999 jeep cherokee.The color codes don't match up between the two vechicles. Having trouble finding wiring diagrams for the two vechicles that are detailed enough to solve my problem.Only need about 9 or 10 wires to tie in to 4.0 computor harness. not sure which ones. Thanks
I've done several of these swaps that sound good at the time but end up being a Huge problem.I would start with the correct harness for the engine you've put in.It must include the under hood harness and what ever harness connects to it thru the firewall to the computer.You'll also need everything connected to the transmission to the computer including any thing connected with the brake and accelerator pedals.Next get the wiring diagrams from Jeep or buy the Chilton or Haynes manual,they have the diagrams included.Get the harnesses connected to the engine,trans and computer,then work backward towards hooking up everything else.I really feel your pain,I've put 20 year newer engines in older cars,V-8's where 6's were,an olds V-8 where a in-line six was(ford),Late model v-8 in a 59' Chevy.All these were simple compared to what your going thru.Please contact me if I can be of any help?
