Has anyone successful installed a gen 3 tuned port injection with origional computer and wiring into their truck? And documented the process? I am not finding much about this on Gen3 sites...THe wiring harness is a monster, and there are 2 computer modules. I also need ideas how to plumb the fuel, type fuel pump, how to run the intake snorkle, where to place the air cleaner, how to kill the theft/key system , ETC.

I feel a bit overwhelmed with this, I may have biten off more than I can chew...I would like this to look decent when complete and not throw error codes. THe specs on the motor and tranny look great, the 305 appears to turn about 235HP stock, and the 350 only turns about 15 more HP in same car...
