Our simplified standalone harness for 98-05 GM 3800 engines is designed for easy setup with new wires and connectors. With just a simple 2-wire connection, installation has never been easier.
These harnesses are compatible with older engine models when paired with a 98-05 ECM. We also have adapters to convert to older style injector harnesses. Please note that these harnesses are intended for off-road use only.
If you have any specific requirements or questions, feel free to let us know!
