• Wiring Harness for Speed Density Ford V8 Engines in Classic Cars and Trucks (Sequential EFI)

(For swapping drivetrain from 85-88 Mustang, 88-92 Truck/Bronco, into classic or custom applications)

We are pleased to introduce this stand alone Ford fuel injection harness sized exclusively for classic Mustangs, Trucks, and Broncos running speed density engines from 88-92 Truck/Bronco with sequential injection by utilizing an aftermarket ECU such as our PiMPxs. This kit is a direct fit and is finished off with hi temp zip loom and harness wrap tape. Works with speed density equipped 302 and 351 engines. This is the complete engine harness from ECU to all engine sensors. System includes a firewall grommet and complete instructions.

Harnesses are drop shipped by Ron Francis via UPS ground service and most of them are made to order (not stocked) so immediate shipment is not expected.
