You're right, I initially had issues with my Fitech, mostly RPM noise (had to add grounds). When I built my new 418 stroker I decided to hide most of the engine compartment wiring by running all of the wiring through the frame rail. I also, with the help of my buddy Larry (64mopar) made a panel that fits under my dash that has my Mallory 6AL, voltage regulator, starter solenoid and 2 fuse blocks. I think this helped with the RPM noise faults as I have none of them now. It runs perfectly.
