I have a 1994 S10 that had a PL-10 Carbine alarm installed for keyless entry only, in the drivers door panel(previous owner). It failed and I want to replace it with an Autopage RF1055KE. It also had an add on relay module. My understanding is the vehicle is a 5 wire reverse polarity set up. I don't understand the wiring colors on the trucks drivers door lock switch. Dk blue, lt blue, black, black, pink. Also the 5 wire relay modules have 8 wires. I understand relays. 5 wire (N.O.87, N.C 87a. , Common 30 , coil 85, coil 86)

5 one on connector and three on the other , The old set up didn't use the small +12v on the three wire plug.

I am waiting on a new relay module I ordered from Commando(https://www.commandocaralarms.com/itemdetails.asp?Productid=553) I am hoping that when the relay module arrives I can sort out some of this out. Can anyone clear up my confusion?

All you needed was a couple of relays ( instead of the relay module ) and hooking it up to the relays like this digram: 5 Wire Alternating 12 Volts Positive Door Locks

Are you saying I can't use a relay module? I thought they were just two relays on a board? I just don't know the pin out of the old one.

Since you already ordered the module....

The module is the samething as the diagram you can find on this website except it has nice wiring and a pretty case. The included instruction should tell you what to look for and how to hook it up.

Good Luck!
