Car Alarms: why do I need 3 relays and socket, power locks, door locks

Question
Why do you tell me I need 3 relays and sockets when you only mention 1.
thanks

Answer
1 for starter kill
2 for lock and unlock

If your truck has power locks and
did not come with a remote, they
are 5 wire reverse

if it has OEM keyless entry
the door locks are positives:

Either way, you need a relay door lock module, or
2 relays 1 for lock and 1 for unlock, do use an aftermarket
alarm, unless it has the capability to do these lock without
relays. Most only provide NEGATIVE (-) door locks/unlock outputs.

I hope this clears up
the confusion.
