Hey I had this problem with a PSI harness and worked on it for Months, Took my truck up to a Builder in Indianapolis and he worked on it for 3 weeks and didn't fix it. After all that. Here's what I did. I carefully took a screw out of the ECM and put a ground wire with a ring terminal under the screw and ran that ground wire directly to the TAC module and put the other end under the bolt holding the TAC module down. You will find 100 posts about grounds, and checking wires, But this is the only thing that worked for me
