ca-425 lock an unlock in honda pilot?

Any one hookup the lock unlock feature in a honda pilot?

Do I need extra relays, if so where do they go? do I have to cut the wires at the switch or can everything be done from the pas kick panel?

Thanks,

so i can just hook right up to these wires with the neg pulse without an external relay?

thanks

meterd out the cylinder wires and your right they are a neg pulse.

hooked up the wires direct and seems to work excellent for now.

thanks!
