Hello everyone,

I just installed a prostart auto starter. It's just test fitted right now and all seems to be working as advertised. I wired direct to my door unlock and lock. Are relays required here? I'm under the impression that I'm tying into a trigger wire, not the actual wire that actuates the solenoid. I'm assuming GM already has that running off of relays as it is. Am I correct in this assumption?

Thanks

No relays needed. Just wire the brown (rs) to green (lock) and the green (rs) to blue / YELLOW (unlock)

Thanks for the quick reply. Thats going to save a lot of work. Is these install situations, when are relays generally needed? Is it only when trying to power a high current item?

Yes

Basically, there are 4 common situations in alarm/remote start installations which require a relay:

1. Output from the control module doesn't have a sufficient amperage to power the factory circuit directly.

2. Output from the control module is the wrong polarity to power the factory circuit directly.

3. A wire on the vehicle needs to be interrupted by an output from the control module.

4. Output from the control module needs to stay isolated from the circuit it's controlling on the vehicle.

In your case, jetmech_jt8, none of the above apply.
