I'll bet you are. I still like the capacitor mod, because it works for those of us using the stock head (can't do without the British lady's voice in the NAV system!

I never looked at the amp wiring until now - haven't even seen it in the service manual, but then, didn't ever go looking for it, either. Having you around will be a plus for the community here.
