Hey Everyone,
I know some of the information that I am hoping to get from this post has been covered somewhat in other threads but they are all from a number of year ago so I thought I would see if there is any new and updated information that all of you might be able to help me with.
I am a relatively new Hummer owner. I have owned an 08 H3 with a 6 speed manual in the past, but now I am the proud owner of an 05 H2 and a 06/08 Hummer H3 Alpha.
The H3 that I had in the past just didn’t have enough power with the l3.7 so I have been keeping my eye open for quite some time for an Alpha. I was able to find a wrecked Alpha on auction and got it for a pretty good price. The front end was toast on it however so I also bought an 06 H3. My plans were to swap the body from the 06 onto the 08 and have me a clean title FrankenAlpha.
I did the swap. The body swapped over very simply. Everything bolted right up. The 06 radiator matched with the 08 Alpha radiator. Really the body swap went so smoothly I was quite surprised. I can see where you all have mentioned that the 06 vs 08 body is tighter on the firewall at the back of the intake on the 5.3l but the Alpha had a foam pad on the back of the intake and that pad just barely rubs the firewall so I don’t think I have any issues there.
So, now to what I am hoping to receive some expert guidance on. I didn’t do my research enough on the wiring. I think if I had swapped an 08 body onto the 08 Alpha my life would be a bit simpler, but with the 06 body the wiring harness from the engine and ECM don’t match up well enough to the harness going up the body of the 06. I am hoping some of you will have expertise or know someone I can contact to help make a custom harness of sorts to simply pair the engine ECM harness from the Alpha to the body of the 06.
Worst case scenario is I strip both H3’s down and swap the entire harness from the 08 into the 06 body, however that is more work than I really want to tackle if there is a more simple solution.
Thanks!
