I am looking for some advise installing a Viper 211HV keyless entry system in my car. The car has an aftermarket wiring harness because it is heavily modified, it has Spal actuators mounted to the factory door locks, they are controlled by single rocker switch. The power locks work perfectly but I would like to be able to lock and unlock the doors with a remote key fob. I have attached a drawing of how the actuators are wired using two relays. I have also attached the wiring for the Viper system. I have bench tested the system, the dome light, parking light, and the positive (12v) leads for the door locks work fine but I believe I need a negative signal to the relays to operate the actuators. I would appreciate some guidance on what wires to use and where on the relays to connect them.
Also the Viper system has an output (200ma) for an extra feature, I would like to use this for a power trunk release. How would I attach the output wire to a relay that would trigger the 12 volt trunk release?
I hope I have explained this clearly.
Thank You!

This wiring will provide a (-) output for Lock and Unlock from the Viper 211HV.
H1/5 to Green wire at switch
H1/6 not used - insulate *the 87 is a typo. It is actually 87A.
H1/7 to Chassis Ground
H1/8 to Blue wire at switch
H1/9 to Chassis Ground
H1/17 not used - insulate

If you want a +12V pulse output from the 211HV'sTrunk Release button use a 30/40 Amp SPDT Bosch style relay as follows :
Relay Pin 85 to 211HV H1/18 RED/WHITE
Relay Pins 86 and 87 to +12V constant through 15 Amp fuse
Relay Pin 30 to Truck Release solenoid

Soldering is fun!

Tonight I spent some time wiring the system as you directed in the above message. Everything works perfectly!! I connected the horn, parking lights and inside courtesy lights, they all function as they should. I really appreciate the help with this issue, You saved me much time and frustration.
