I just so happen to know a lazy bum who lives in Houston that makes front mount turbo kits. I'll be calling him up and having him deliver/install it :jest:

Make sure every connection matches the factory harness.

Does anyone have any pinouts for our trucks. I'm looking to swap out my 4 speed out of my 07 nnbs VMax with a 6L80e out of a 2011 which I also have the full harness from. I was hoping that the harness pinouts that plug into the truck under the hood were the same for 07&11.

Nelson Performance did a swap without a harness. He just repins the original harness, and adds the necessary plugs. So it can be done.

I'll call Nelson tomorrow. I was just wondering if I can use the 2011 harness in my 07 cause it is in New shape.

We should be finishing up the 6-spd swap this week in RickLowpez's truck. So far its been very simple and easy. We will put a detailed write up on what is needed with some pics etc when its done.
