FI engine removal

I have not had any luck selling my 4.0 so I am going to remove it to hopefully use in a cj 5 I found yesterday. My question is how much of the wireing harness ect needs to come with it in order for it to work in the cj-5?

Re: FI engine removal

I've not had the pleasure of removing a Jeep FI engine yet. I have done a couple dozen GM FI engines. Basically, start with the ECM (computer) wiring harness, and work until all the connectors are removed from the engine. With the GM systems, there are usually about 6 wires going under the dash to the Service Engine Soon (SES) light and ALDL terminal. With the GM system there are usually about 4 wires under the hood going to the fuse block connector from the ECM also.
