Hello Dave, thank you for feedback.
As you have noticed, i have repined the L31 vortec engine (underhood) wiring for 0411 PCM, that can control and the vortec injectors and the 4l60e.

You are absolutly right it is challanging, i am braking my brain for this setup, still thinking should i keep the underhood fusebox, i know folks choose to cut it out, to make the wiring more simple and neat. The L31 underhood with 0411, can work by it self, controling everything and the 4L60E, with out the incabin wiring, like most make a bench for L31.
But want to merge everything to work together. I wonder why there is still no rewiring schem or file out in the net yet for this setup, like Lextech has made for the 0411 repining file, it's realy a mistery..
