I guess its just not well documented anywhere that I know of, now if we could all just get a direct feed from your brain that would be awesome 

I actually didn't mind going over the wiring diagrams since I'm an electrical engineer, I will say that the pin-outs are really all you need, but it does take some time if you don't know the supra wiring harness in your head Other than my fuel pump control issue everything went smoothly and like I said the car fired right up without a hitch. I did learn that if you are using the stock fuel ecu you need to set the fuel-pump control to the EST15 output and reverse the polarity.  

I think my install guide will make the install a little more DIY friendly than what is currently out there.

Today I changed my fuel pump wiring so that each pump is controlled individually directly from the ProEFI bypassing the stock fuel ECU and that is working perfectly now. I also wired up my meth injection through a solid state relay to the ProEFI so that I can do progressive control. The progressive control was working for me, but I discovered a fairly large leak from my meth pump Rather than try to rebuild it and replace the seals I decided to just get a whole new one. Other than that I started to put the fender liners and some other items back on the car.  

Couple more quick teaser videos. Hopefully I'll be buttoning up everything and getting it off the jackstands soon.
