(1*) must isolate this wire when doing a remote start. in order to isolate use a relay
If you have a (+) ignition output on the remote start cut the black/orange wire hook up the ignition out from the remote start to pin 86 on the relay hook pin 85 up to ground. Hook pin 87A up to the black/orange wire coming off the key cylinder. Hook pin 30 up to the black/Orange wire going away from the key cylinder. Hook pin 87 up to constant 12volts
If you have a (-) igntion output on the remote start cut the black/orange wire hook up the ignition out from the remote start to pin 85 on the relay hook pin 86 up to up to constant 12volts . Hook pin 87A up to the black/orange wire coming off the key cylinder. Hook pin 30 up to the black/Orange wire going away from the key cylinder. Hook pin 87 up to constant 12volts
If you have a factory alarm you can disable it by pulsing the blue keysence wire coming off the key cylinder with a ground signal.
ENJOY!!!
