Electronically Fuel Inject your classic Mustang! This is a brand new wiring harness for the EFI 5.0 Stang (from RJM Technologies) to fuel inject your car with one of the most available EFI systems around. You would just need to grab a computer (easily found cheaply) among other EFI-specific items. I bought this part from RJM Injection Technologies as it went with the theme of my rebuld ; classic car with modern superior technologies integrated. It cost me $575. I will sell for $400. I'd like to free up my garage! We can discuss shipping. Contact me with questions or anything via this thread, StangNet message box, or email me directly at [email protected] for quickest response. I am selling this along with many other parts because unfortunately, I was unable to even begin my project (1967 Coupe – S Code). Medical issues came upL. However I have a full garage of brand new modern parts looking for the right owner! Parts such as an Autometer gauge cluster, kick panels with speaker cutouts, MSD 6AL ignition, TCP power rack & pinion steering with Flaming River adjustable steering column, blueprinted 306 beast of an engine, Kenne Bell blower, black Procar Elite Bucket seats with matching back seats, and so much more. Heck, I’d sell the rolling shell if the right offer came around (otherwise I’ll save it for a project in 10 years or so.
