GM HOT ROD HARNESSES
GM Harnesses
GM Hot Rod Style Harnesses
We develop form-fitted engine harnesses for GM engines, utilizing all new wire and OEM components. The object of these wiring harnesses is to have the wires well organized on the engine so that they disappear as much as possible and don’t detract from the look of the engine; all this while functioning to the complete OEM specs for engine control and performance.
This is a self-contained engine and transmission control system that comes with its own fuse block and relays. In each of our harnesses all of the connections are labeled and placed in their proper location for ease of installation.
We can program customer OBD2 computers or we can provide new, programmed OEM computers.
