I have a bunch of harness's for sale. 1st: 89 5.0 Engine Wiring Harness. $85 + shipping. 2nd: 92 Engine Harness from a truck or other vehicle. Instead of having two 10 pin connectors for the injector harness, it has two 8 pin connectors. As far as I can tell, you could use it in a Mustang if you bought a different injector harness from an F-150. $60 + shipping 3rd: 87 Mustang Taillight harness. Not the wires that run the whole car though. $15 + shipping 4th: Tail light harness from a Mustang as well I think... $15 + shipping 5th: Headlight harness from a Mustang(I think). $15 + shipping I can combine things and lower prices if you want more than one item. Let me know! Sorry if this is the wrong section... wasn't sure if it would be interior or drivetrain.
