Installing a remote starter without cutting factory wires?

[CTScott]

You don't have to cut any wires - Use tap splices as mentioned. Also, the wire gauge is 16-18 on all of the wires, as our keyswitch is a control circuit, not a power circuit as on many older vehicles. Our keyswitch powers a relay coil, where the relay's contacts then do the high current switching.

The only reason to cut wires would be if you wanted to have the anti-grind feature, which disables the starter when the car has been started by the remote starter. This keeps you remote starting, then getting in the car and accidentally cranking the starter. When I install remote starters on my own cars, I don't bother with the anti-grind feature, but always use it on my wife's car.
