To bypass the radio, you will need to get a Pac TR7 and a standard relay. The relay wiring will be:
85 - Blue wire on the TR7
86 - White eand Orange wire from the TR7
87 - Tied to 86 on the relay
30 - parking break wire on the Pioneer
Wiring for the TR7:
Red - ignition source
Black - ground
Green - remote wire on the Pioneer
Orange - 86 & 87 on the relay
White - 86 & 87 on the relay
Blue - 85 on the relay
The TR7 will need to be setup for feature 12. The settings will be:
Option 1 - 1 delayed on for Blue
Option 2 - 2 delayed off for White
Option 3 - 1 delayed for Orange
Duration 1 - 040 (40 seconds)
Duration 2 - 045 (45 seconds)
Duration 3 - 050 (50 seconds)
The way that it works is: the radio remote provides the + trigger to the TR7. The TR7 then supplies ground to the white wire for 45 seconds. After 40 seconds, the TR7 supplies power to the blue wire. This triggers the relay and sends ground to the pioneer parking break wire. After 5 seconds, the TR7 then puts the white wire to open and the relay then goes to open for 5 seconds. After that, the TR7 will then put ground on the orange wire causing the relay to trigger sending ground to the pioneer.
this is exactly what i did, and it worked like a champ on three cars (two app radios and one app radio 2)
