The one suggestion that I would have for anyone installing a FiTech is to use a ground strap from one of the 4 throttle body mounting bolt/studs to the
battery ground connection on the block. Might be overkill but since the FiTech harness doesn't have a ground wire they rely on a ground connection through the 4 mount studs, intake, heads to block or just head if your
battery ground is there. One could have many dissimilar metals along that path. It never hurts to have it well grounded. I have read on other forums (non mopar) about guys having issues and then ran a ground wire to the TBI body and all the issues went away. On my install on my son's truck that was the first thing I did once realizing the wiring harness to the ECU only had power wires. That comes from 45 years of electronics experience. If you look at the Holley Sniper wiring, they have a BATT(-) wire. I don't know why FiTech wouldn't have considered this. My 2 cents.
