Product Description

Direct Replacement Harness
If your stock Foxbody fuel injector harness is damaged, melted, or cut in your 1987-1993 Mustang, this harness from Ron Francis Wiring can make the repair! Featuring pre-loomed wires and factory connections, this direct replacement harness is the perfect plug and play replacement harness. This wiring connects the injectors and sensors on top of the engine to the main vehicle harness at the back of the engine.

High Quality Construction
Following factory dimensions, this harness is cut to perfectly replace your stock harness. With factory type connectors, you can easily plug the harness straight up to your OEM plugs for a quick and easy installation. All of the high quality crosslink automotive grade wires are wrapped in a high temp covering to protect them from hot components in your engine bay.

Perfect for EFI swaps on 1979-1985 Mustangs!

Image uploaded by Jim Tunstell If you are the owner of a 1987-1993 Mustang 5.0, and you have idle speed control issues even though you KNOW you have installed/setup everything CORRECTLY, rip off your ~ 20 year old harness and replace it with this one!!! My car runs PERFECTLY now, the idle speed and driving characteristics are like a brand new car. The idle now STAYS at 750rpm (stock camshaft) with or without A/C-lights-dual cooling fans, etc running. If you are installing a new engine in your ride, don’t reinstall that OLD injector harness, USE THIS NEW ONE!!! I’ve had my car since new (March 28, 1991) and I am glad ALL the EFI electrical demons have officially been SLAPPED DOWN. Thanks LRS!!! I will probably buy a SPARE one of these harnesses for my spare parts stash. BTW, think you can convince the Ron Francis crew to build the COMPUTER harness for the 91-93 5.0L cars? I would buy one tomorrow if you started selling them….

Yes, I would recommend this item to a friend!

for a BRAND harness this company should be ashamed of themselves. The 12v power supply in round black connector wasn't pushed into lock all the way and wouldn't seat and while trying to fix that connection a connector next to fell out
