TAC module plugs
TAC module plugs Does the TAC module for a 2003 5.3 only have two plugs on it? I have one plug on my engine harness and I assume that there is a small harness that goes from the accelerator pedal to the TAC module. I tried a search, but have not found a good picture or description of the TAC module and its harness.

TAC Module Yep, short wiring harness that should have come with the module or your ETC gas pedal. Will have connector plugs for each end. Get a pcv valve cover grommet at Auto zone to seal it off when you run it through a hole in your firewall.This short harness isn't attached to the engine harness so they don't always give it to you unless you ask for the pedal, tac module and harness when you buy your engine. Picked mine up at salvage yard with pedal and TAC module for $35.
