QUESTION: My 16-year-old son and I are about to take on a special diesel project together: building a diesel-powered Chevrolet Camaro. The donor car is an ’02 model, and the engine is an ’06 6.6L Duramax LBZ with an Allison 1000 automatic transmission. We are at a bit of a loss regarding what to do about the wiring, as the harness and ECM that came with the engine and transmission look a bit suspect. We have the mechanical and plumbing aspects of shoehorning the engine and transmission into the Camaro covered. Is there anyone out there who might be able to get us on the right wiring path before we dive headlong into our sleeper?
ANSWER: It sounds like a fun project that will definitely turn more than a few heads. We know of at least two Duramax/Allison wiring-solution sources, both in Florida: DMAX Swap [(816) 866-3629] and Standalone Harnesses [(321) 604-1963]. Both can provide the wiring harnesses to make integrating the engine and transmission as easy as possible or rework your existing harnesses to do the job. DMAX can also handle the ECM/TCM calibrating at the same time and maybe provide some specific information about the diesel swap you’re doing, as the crew has done at least one similar installation in a Camaro. Ken Wolkens at Standalone is a retired GM engineer who knows Duramax/Allison wiring logic inside and out, and he also custom builds harnesses to fit just about any Duramax swap. Between the two suppliers, you and your son should be good to go.
Duramax diesel-engine swaps are becoming increasingly popular now that there are many viable sources throughout the U.S. for the wiring harnesses that simplify the conversion process.
