Well there are a couple of ways to bypass the clutch. One way is to use a wire that is a "ground when remote starting" to trigger the clutch switch bypass relay. I belive that the anti grind wire , if your alarm has one, can be used. I haven't read this entire thread but i belive it is the method to which you are referring. Hopefully you have an install manual which gives some kind of a descriptor of what the various wires do. If your not sure then you may have to test the remaining wires to find such a ground.
Try this thread to see if it helps:
Also, is this relay a failsafe only, or is it necessary for operation?
Many Thanks in advance
I am not sure what you meant by this? Which relay are you referring to?
If your asking if the alarm will still work if the remote starter doesn't work then the answer is yes. The alarm still works but you wont be able to remote start.
