94 Mustang door locks

I get this reading, "both motor legs of the door locks are normally open. They neither rest at ground or 12v(+). The switch, when moved in either direction, applies both power and ground directly to them without the use of any relays." And wire it to a BW-3000 as per the diagram But when I hook it ,it blows a 20A fuse!

When not wired to the car the relays function properly.  

How many amps does factory actuators draw?

You have whats called a five wire set up.  Refer to the relay diagram for the proper configuration.

Thanks for all your help guys,

After testing again I found that i do have a 5 wire setup ,I guess i did'nt have a good ground on my meter while testing the first time.
