Our typical configuration for this harness keeps the stock S10 ECM in the original location on the overflow tank under the hood.

Custom orders can be built if your installation does not fall under the above selections.

All S/T Truck Vehicle Integration harnesses include wiring for A/C, Starter, factory gauges, and ABS. All factory functions of the truck can be retained with this product.

This harness does not contain any engine control functions.

The Stock truck ECM will need to be retained to make use of all the functions provided in this harness.
