doorlock problems on viper 560xv

I have a 1986 Chevy C-10 with a Viper 560XV alarm. The remote start is disactivated because its carbed.

I recently purchased a set of DEI 524T door lock actuators so I can add the power lock feature to use with the alarm (the truck has power NOTHING). The alarm has a the blue and green door locks wires that plugs right into the brain. The actuators are fully mounted. When I wired the actuators to the door lock wires I get several pulses and the door lock actuators will not function correctly. The actuators go up and down a few times when the lock button is pressed. I get nothing on the unlock.

I used relays and wired them like the diagram on this website for added actuators and that still did not fix the problem.

Could the alarm be the problem? According to the information provided by the alarm, they are sending out positive triggers, my door lock actuators are two-wire.

Its been a while since I have touched a car but I was an installer many years ago and never had this problem.

Any assistance would be greatly appreciated.

I did use relays but the ones I have are 4 prong, the ones on this website say to use a 5 prong.

I plan to eventually add a switch, and thinking about it as I type, I should just go ahead and add it now.

thanks for the info, 87a isn't used in the reverse polarity diagram for the door locks so would my relays work?  Just to verify that is the relay setup I have to use (4-relay reverse polarity)?

Its been such a long time since I fiddled with all this stuff...

yes 87a is used for that reverse polarity diagram, you would need two single pole double throw relays.

I went out an purchased that STDP relays and wired like instructed in the diagram. The door locks still do not work with the alarm.
