I’ve done so much stuff in such a short period it’s hard to remember the details but I know I didn’t have to extend anything off the ECU connections. It BARELY reached where I mounted it, although it is kind of an awkward mounting location because of the wiring length. Wasn’t worth extending every ECU harness wire just to pull the ECU a few inches further out into the glove box though. I had to extend about 6-8 wires that form a ground bundle and that was about it. Aside from that, I cut the loom apart and decoupled the alternator feed from the injector part of the harness to give it more length. I then used that to go to a junction block under the dash so you can pull that and the rear of the harness under the dash. I then built a new alternator cable that ran from the alternator to the other side of that junction block under the dash and loomed that back into the harness with some matching loom tape so it looks seamless.
Did you have to extend any wires on the mopar harness to get everything mounted under the dash? Some have told me it wouldn't be long enough.
