Just wondering what a guy with a 88 to 93 5.0 or 5.8w needs to hook up to run it in a buggy

you'll need a whole engine wiring harness, assuming you are wiring savvy you can find a wrecked vehicle that originally had the 5.0 in it and pull the wiring out of the front and seperate what you need and dont need,such as the efi wiring .

My jeep has a 5.0 out of a mustang in it. I didn't do the swap but it had definitely more than 5 wires

I just did a swap in my EB and there really isn't a whole lot to hook up. Beyond the sensors that plug into the motor there is a few 12v wires, a 12v rank wire and a few grounds. Beyond that there is nothing - I hooked 3 power wires up, two grounds and that was it.

This is what I used


You can see my old mess here, and I`ll have to get some new pics of how it's setup now, all nice and clean

I actually purchased all new electronics minus injectors and had IHO Jeff re-do the entire harness, mounts, and EVERYTHING on the engine. It's AMAZING how much better it runs

He needs to ditch the EFI/TFI setup (or at least go with the firewall mounted TFI), go carb, and then duraspark it. Then you will have this

>only used 3 or 5 wires and i was also wondering about the o2 sensor

If you keep the TFI setup, you can buy generic bungs from Summit and use the replacement Bosch, it should be a simple non-heated 1 wire type (ECC-IV) vs. 4 wire OBDII. Just keep the connectors clean of grease and such as it breathes through the wiring harness.

Personally, I would go with the blue box duraspark and convert it to carb, but, that is me. Some people like the EFI alot.

Here is a thread on my EFI swap - I had everything hooked up correctly on my first try, I didn't realize they previous owner used a switch to turn on the fuel pump, as the wiring was no longer hooked up to the relay.
