Hi,

Back on the forum after several years away. I currently have a 6.5TD Hummer that needs a new engine and tranny - so my obvious thought was to do a Duramax/Allison conversion, like what are in the new 2006 H1 Alpha's. Seems that I can buy the bits for about the same as a new long-block. The fabrication will cost - but that's part of the adventure.

Have been readings, searching, and browing the various archives here over the past two days and haven't been able to find technical details or detailed know-how from someone who has done one (or more) Duramax conversions. Jim's articles are good - but lack details and the nitty-gritty of getting into the conversion and the got-cha's that you have along the way. Perhaps I'm searching the wrong places, or using the wrong words..

Specifically, I'm interested in the electrical bits - interfacing the DMax wiring into something that's not designed to talk to 6.5TD. The mechanical/fabrication bits seems straight forward - but interfacing the engine and chassis harness I am betting is the difficult part.

So has anyone written up their specific experiences about splicing and tying a non-DMax truck into a DMax harness?

Sure, I could pay someone 50K to do a conversion for me - but if I'm going to live with this beast for years, I need to know the in's and out's of solving problems and understanding how it's been put together and squeezed in . Still, I'd rather not make all those discoveries on my own - and willing to learn from those who have blazed the trail before me....

Looking forward to learning deep secrets!

Cheers,

Clarke
