LQ4 Wire Harness

The LQ4 / Vin U / 6000 engine is an awesome GM power-plant, similarly related, by looks, to the 4.8 LR4 & 5.3 LM7 but is massively in a class of it own. This engine is the foundation for a stroker motor, and when you need more room the LQ4 engine is the suburban of the LS blocks. With a great engine builder, the sky is the limit for horse power and torque, endless possibilities.

Speed Scene Wiring fabricates this fuel injected wire harness, with emissions or without. If you require this engine in a marine environment, we can accommodate with the correct computer program. The nice thing about running a SSW wire harness, and GM electronics are diagnostic capabilities, great customer service and a product that is Made in the USA.
