how to bypass pioneer avh-2400bt

I don't remember putting a relay on my z120bt. Was a while ago so maybe I just forgot.

Thought I just switched some wires around on the harness

Yeah on older HU's you could just wire the parking brake wire directly to the ground. Then they changed the HU's so you needed a relay.

Now it seems the the newest HU's need a double pulse relay.

More detail on the momentary interrupt switch? It has a double pulse for the newer HU's?

That's because that's not an AVH unit, it's an AVIC. The AVIC's require you to move the mute wire (at least the 120 and 920+) down or up one pin (depending on how you're holding it) then ground that and the ebrake.
