It's been pretty dang solid the past few times I drove the car since doing the regulator relay mod, even at idle. Lights still dim a bit but no more flickering. I'll have to dive deep into my wiring to find the bad connection as I did the ammeter bypass slightly different than the "MAD" method I just forget how exactly. I also want to move the ON signal for my wideband O2 sensor so it doesn't turn on with the key in Accessory position, I'm afraid I'm gonna burn it up.
