My plans are for a Speartech harness and PCMs. Not the cheapest out there, but it's complete and easy. Honestly, I'm pretty sure he just buys it from GMPerformance Parts and tunes it, but that's fine with me.

So now I'm just hunting for an engine. Once I have those, then finding accessory drive, headers and the small stuff will start.

Slow down killer, If you already have a E38 ECM (1st pic), And remove the TCM/Control Valve assembly. You can send both modules to Speartech for reprogramming. NO need to buy new.

I would like to idenify the ECM you have, The second pic is a E40 ECM..Later E67 ECMs look similar...3 plugs. The E38 ECM you need has 2 plugs.

If you need help removing/installing the TCM let me know.
