    Default EFI wiring harness

    Ok guys im working on swapping a fuel injected 5.0 or 5.7 into an older carbed truck. My question is how big of a pain is it to use the wiring harness outta the donor truck and making it work in my rig? And whats the quickest way to sort out the b.s. and just get what I need?
    Any help would be appreciated!!! Thanks

    It's not bad if you understand wires. If you don't, then get a Howell harness and be done with it. It's like a 4 wire hookup.

    I found a company that will rework the one off of my donor truck and basically make it a stand alone for 300$ plus shipping. Would that be worth it or would I be better off paying the extra for a new one? http://www.my-efi.com/

    It might be awhile before Tim answers. He's on vacation in hillbilly country.

    I have seen the ones from places you send your stock harness into. Some are very good others not so much. Research them. I am sending my harness in when I do the big block swap on the buggy this winter.

    It should be pretty simple, if your swapping in a mid 90's or newer motor. Assuming your swapping in a small block Chevy, you can easily obtain many of the parts youll need from a junked truck. Youll mainly need you air pressure sensors, fuel/air ratio monitors, and your oxygen sensors, which can be found in a downtube screwed into the header. To control all of this, MSD makes a controller/ECU/programmer that this can all be wired into, so you dont have to mess with the original ECU. Ive seen people do this all the time into their older carbed jeep cj's, so it shouldnt be too daunting of a task. Hope this helps!

    I have to point out a few things here....and i'll try not to sound like a dick but I am sure someone is going to take it that way.

    Air pressure sensors? I got nothing for this except what are they?

    fuel/air ratio monitors ARE the O2 sensors. Most 90's chevs only had one. Some had 2, one on each side but most had one.

    MSD only makes one computer setup for fuel injection and it's a complete fuel setup for over 2000 bucks. I think you are confusing MSD ignition boxes with fuel management.

    If the OP is getting a motor and the whole harness, then using the stock ECU should not be too hard to "mess with". It's simply plug and play.

    Painless makes a harness for 435, Howell has one for 325.
