rv alarm door lock problem

I'm putting an alarm in a customers RV its a 01 Ford E450 made by Jayco. I can only get the driver door to lock and unlock using a 5 wire relay hook up. I can't get the passenger side to work. The wire colors on the car that I used were driver door lock pink/black. Driver unlock pink/orange. Passenger door lock red, pass. unlock brown. The wires test at like 1.5 millivolts. Then when I hit the switch go to 0v then directly to 12v. I tried just hooking up the door lock wires by themselves but it did nothing. I need help. The alarm is a basic autopage rf-315. Thanks

Could someone explain the right way to wire up a five wire door lock?

Ok I just found out its a 5 wire reverse polarity door lock. So how do I wire this up. Do I still use the relays?

probably like the e150-e350 vans, red(unlock) and brown(lock) are lock unlock reverse polarity with passenger switch being master if vehicle didnt have factory keyless, if it has factorykeyless wires will be negative pink/lt green(u/l) and pink / YELLOW(l)if no keyless 5 wire relays ---pin85 to negative lock output from system, pin 86&pin87to 12 volt constant,pin 87a to switch side(side that still lights testlight when hitting lock on pass switch) pin 30 to motor(side going into driver door boot)of brown wire use same relay wiring for red unlock except pin85 use negative unlock output from your system

Ok thanks I got it finished today. It was the way Jim Hunter said. So thanks for the great info.
