Swap 5.7 vortec in Jeep CJ7

[silver97]

I have a complete 5.7 with ecm and engine wiring harness from a 97 truck that I want to swap into a jeep CJ 7. I do not have the interior harness. Which wires do I have to connect to get it to run? Does anyone know or can point me in the right direction to run this engine in a stand alone configuration?

You can download the manual for that truck from the file section and look at the wire diagram. I would contact lextec by email and get a pilot to 0411 swap it. 100 bucks off equipment and free software and you can tune the 0411 yourself. Maybe someone else will be of more help

I have a 0411 from him that I never used. I lost the paperwork/email that showed the pinout. It needs the 4l80E deleted. I;m running a TH400 in the jeep. I don't have the part of the harness that has the OBD2 port. Is there a workaround?

Junk yard for the obd2 plug and a chunk of harness. I would email him again and explain your predicament. He might still have a copy of the email he could resend

You can find the pin out for the C100 connector either via a search on here or by delving into the factory service manuals that are stickies. That's the big old honkin firewall connector. You also have some wires that go through on the passenger side, but those are just for the gauges.

why not leave it 304-360 AMC. Not enough early CJ7's left original

They're low compression dogs, but mine had a little 4 banger which I didn't miss at all when I swapped in a 6.0.

My 85/86 don't remember is 258 auto and air with a hard top and it all works. Great rig for putting around off road and staying cool with no bugs lol. Sucks on freeway though

All I have is the 350 for this build. My other CJ7 has the 258
