keyless entry help!

[lt1s10]

just ordered and received a valet keyless entry system from a1 electric for a 1985 el camino. there is no instructions with it so i called the guy he says i have to carry it to a dealer to have it installed which I'm not gonna do (ill send it back first), but the only thing i need to know is the 2 wires going to the lock motors has to go through a relay and it sounds like you would need 2 dif. relays to make it work.( one for up and one for down) does anybody have any info on remote keyless entry wiring from the module to the door lock switch? no relays came with the kit. if i knew if the 2 wires from the module going to the relay was to ground the relay or make it switch hot i could hook it up anyhow. any help would be appreciated.
