Do I need relays for power door locks?

[ibuytoys]

I am installing an Alpine SEC-100S alarm into my '97 4-Dr. XLT. Do I need to add additional power door lock relays or is the X equipped from the factory with relays already? The alarm doesn't have built in PDL relays but only low curent outputs. Thanks.

I know that my model year (94) needed relays, but my alarm's brain came with them included.

No you should not. The 97 XLT should have a 3 wire negative pulse door lock system

Thank you for your replies! I will be installing it shortly.
