im in the process of setting up the wiring harness for another 3500 swap. last time i just wired the engine and havent had any gauges, but im not doing that again lol. my question is the c100 calls for a uart feed and datalink feed. im using the v6 pcm data link feed because i want to be able to connect to it through the obdII port. but for the uart, i am under the impression the gauges r run off the uart, so i figure feed it by the j body pcm but my diagram in the hanes manual shows that the uart line just goes from the c100 to the data link connector? so do i put the j uart line to the c100? i feel like im over thinking it but couldnt hurt to ask.

thanx guys
