2000 chev K2500, Start and Die

Masters........all of you!  Thank you.

What configuration and how many relays do I use for this truck for door locks? It has power locks from the factory withou keyless entry.  I am confussed as to how many relazys I need to use 2 or four and what exactly the configuration is called.  I bought the reference cd from 12 v so I have the schematics on how to do it once I know which one to use. 

Thanks,

If your truck came WITHOUT Keyless Entry ... U will need 2 SPDT Relays for Lock & UNLock

Thanks again.

This town in sold out of 555l's but I have found a Data port module at another shop that will get around pass lock that I will get after work and try.  Thankd for the door lock info too.  I will use a total of two relays as shown in the instruction of RS 850 (5 wire alternating door lock).

Thanks  Again

I could not find any in my rush last night so I will look again tonight for something like that when I pick up the bypass module.  It sucked having to drive this truck to work today with my dash torn apart and wiring strewn out all over the place.  Not to mention it has been the only thing on my mind all day while trying to work.

Mucho thanks
