Community Q&A Question: This kit seems incomplete?

Asking About: Mustang Pro-M Mass Air Conversion Wiring Harness (86-88) 5.0


This kit seems incomplete?

It seems for the conversion to work right you need to splice in to the VSS and also the fuel pump relay under the driver seat. All the other kits I've seen include the wiring for this and this one doesn't seem to? I would rather order from you guys, so can you please elaborate on this?

U don't have to splice into anything. You pull your ecm out and move some pins around and connect the wires into the slots. It's very simple and has great direction. Just remember u will need to buy a mass air computer for your car and take the vacuum off the map sensor on the fire wall next to the vacuum tree.

You do have to splice two wires, the ground and power wire going into the ECM. It is not as daunting as it sounds, but the wires are a tight fit. The directions are pretty clear, but to figure out the pin placement, I had to Google a diagram of the wiring harness. - Steven last year
