Speedway Motors 91008592 Details

Take the fear out of electronic fuel injection! These engine wiring harnesses are designed to make your engine transplant effortless. Each new harness contains in-depth application-specific instruction sheets, clearly marked factory GM connectors, labeled GXL jacketed wire, GM color coding, and pre-fitted corrugated slit loom for an extra value and professional look. All un-needed emissions wiring is eliminated to make the install as simple and reliable as possible.

Made from premium grade GXL jacketed automotive wire
Most wiring is larger gauge than stock application for durability
No splices to reduce points of failure
All primary grounding is done at the head or block and grounding points are isolated from each other to reduce electrical interference and minimize ground looping
Harness wiring matches GM wiring configuration and jacket colors follow GM color coding for easy identification
All electrical connectors are made by Delphi or Packard and are direct fit for GM cars and trucks
Can be installed to run engine in 20 minutes, but figure 4-6 hours for a professional installation
OBD1 diagnostic port for connection to scanners and tuning tools

They find the product exceptionally useful for TBI engine swaps, citing that everything is well labeled and in the correct place, saving them significant time and effort. The harness is recognized for its adaptability in various setups, such as Jeep YJs and old trucks, and praised for its excellent fit in their systems without requiring any modifications.

We have used two of these harnesses on two Jeep YJ engine swaps. We use engines from 1992. One jeep was an Auto and the other a 5 speed manual. No issues. Very easy to connect. The hardest part was finding a place inside the Jeep tub to put the ECM. Behind the glove box worked best.
