Fuse Box / Relay Upgrade:
The stand-alone engine harness is supplied with everything needed for your engine to run, with all the correct fuses and relays necessary. It includes a relay circuit for one fuel pump and an ignition relay to power up all injectors and coil packs etc.Some vehicles already have a starter relay, thermo fan(s) and any other add-on circuits added to their vehicle. Our fuse/relay box upgrade is designed for vehicles that require those circuits to be added on with all wiring lengths, connectors and terminals pre-made ready for you to connect.All wiring is added into the existing harness to allow for a neater finish.We are also happy to add any extra circuits into our fuse/relay box that you have added to your vehicle. If so, please contact us.

Cloth Taped Harness [Show Package]:
The stand-alone engine harness is finished in a conduit sleeving and GM harness tape to suit conversions that don’t require a detailed show finish and prefer a more factory look.For conversions that require a show finish harness, the upgraded show package includes an overall harness modification to the lengths of each component of the engine bay, allowing you to run the harness much neater then factory to create a more hidden wiring look on your engine, and comes with a complete wrap of a stylish cloth tape of the complete engine harness from the engine bay, to the under-dash wiring.
