I had this code a few time in the Suburban, ('04 electronics), I checked everything, Never actually found a smoking gun. Then I realized it only gave the dead pedal/U0107 when I started it after sitting a long time (Over 3 weeks), Using a Battery maintainer fixed it for me.

But your issue sounds different, I would start with Grounds, The Factory TAC module ground is G104 at the back of the block, Your aftermarket harness may have it elsewhere?

What is the Charging Voltage?

How old is your Battery?
