    Did they ever give a reason as to why? I can't think of any logical reason as to why relays would not work in a negative trigger setup. I can see why positive would not work with a typical automotive relay since they need 12v. I guarantee the mute output will work with a relay just off the principle of it being grounded properly enough to trigger a radio's negative mute trigger. I would diode isolate the 85 terminal on the relay just because I don't where the 5v standby voltage is coming from in the ALP (some relays have internal diodes for this btw).

    :edit: What is the ALP "fog" wire doing during standby and activation? I'm assuming 12v on and either ground or 5v off? If so that should work for a positive relay trigger. Just trying to figure this out since their response doesn't make sense to me.
