Hey gang --

I have been trying to search for an understandable solution to what I'm trying to accomplish -- but to no avail thus far. Here's what I have:

I have a sbc 350 with carburetor that I've put into my '93 YJ jeep. For various reasons, I want to install a TBI system. I've purchased a complete TBI system off of a '90 suburban -- wiring harness and all. I've got everything figured out (I think) to make the switch EXCEPT what I really need to wire up into my existing system. Like I said, I have already wired up a working sbc 350 with carburetor -- and I've been trying to locate a good electrical diagram of the harness to limited luck.

I'm hoping that I am going to essentially only need a few power wires and grounds, maybe along with the O2 sensor I need to add, to make this all work -- but I'm hoping someone with a more solid understanding of what I am actually going to need or not need, can help me out. I essentially need to figure out what wires from the factory hookup harness that would've gone through the firewall -- I am actually going to need to use, and those that I don't.

Anybody done this and/or know more about what I'm trying to accomplish and can steer me in the right direction? Much help appreciated...I've been trying to reach the answer prior to soliciting for help -- but now here I am.

Cheers and thanks in advance!

Thanks again!

You need an ECM, a computer, to run any EFI setup. Not sure if you got the factory computer too, and if not, you may want to check out MegaSquirt; just google it.

Make your way over to the EFI forum on chevytalk.org, lot's of this type of stuff going on over there.

Good luck
