Question about 5-wire actuator

I have a 5 wire actuator as part of  4-door central lock and alarm. The actuator worked when i hooked up the module to a battery in my house but does not work in car. I measured 12 volts between two of the wire but the actuator does not work. i even hooked up a 2 wire actuator to the 12 volts and nothing happened. the wires are about 12 ft long.

This describes a 5 wire lock. not sure if this is what i have. I don't see how it works.  i know 85-86 is the coil and when the coil is energized a switch pivots on 30 from 87a to 87. i don't see how polarity is changed

Ok, i will check this out. I am only using an actuator on the drivers door as locking the drivers door locks passenger door.  It was working well with one actuator connected before.

I only have one 5 wire actuator. according to the alarm schematic it is hooked up to both the driver and passenger actuators . There are two additional wires for the other 2 doors. The total number wires in the harness is 7.

I had the wires mixed up going to 5-wire actuator.  The 12 volts between the wires disappeared when they hooked up with alarm module.

I now have the led blinking 7 times and going off which is supposed to mean there was power off. and after about a minute the doors unlock with out any input. i'm going to try using a 2-wire actuator and see what happens. this will free up wires for my power windows remote.
