I have a 2018 Charger R/T and I recently did the 6.4 intake manifold swap. I got the MMX SRV controller to get the full benefits of the active runners, but when it comes to tapping the fuse and I tap it with the ASD FEED #2 like they recommend, sometimes it prevents the car from starting. Is there any other fuse I can tap the fuse into? They said it can be any 12 volt fuse that is on with the ignition / key on. Thanks In advance!

The underside of the fuse box lid has a diagram of each fuse & relay and their amps/function.
The whole car is 12v, that's DC voltage.
It's the amps that matter, and I'd recommend at least 15amps for the tap.
Anything that's on with ignition like heater, ac, radio etc. Don't use lights, horn or airbags.
