Create AUX Channel In Factory Keyless

i have RS901 hooked up to the point where i can start engine by hitting ground with green wire 3 times. so now i'm not sure what i need to get this working from my factory remotes. i tried getting ground from factory lock/unlock wire, but timing is way too fast on that wire.   how can i create aux channel or whatever the heck i need to triger this form my oem remotes.    i have buick rend. 2004

what do you mean the time is too fast? did it work?Houston,TX

no, i tried factory arm/disarm wire but Ground pulse on that wire is not a clean ground, it has resistance on it.

by saying arm/disramr wire i mean lock/unlock wire.

Go to the factory doorlock motor wire-----that is, the wire that goes to the doorlock actuator itself-----on nearly all cars, it'll be a strong positive when you lock the doors. Then use a relay to invert that positive to a ground. 85 and 87: ground 86: factory doorlock motor wire 30: this will now show a ground every time you operate the locks.
