i was wondering if any one has the wiring diagram for the alarm system viper 350HV. im trying to just add power door lock actuators to my car so my silly friends dont have to lock my doors. also if someone can show me some door lock actuators and how to wire them.

 

you need 2 relays or the DEI 451m relay pack (actually better). I'll see if I can post the diagram a lil later.

 

^^^

 

You can get basic actuators, from any car audio shop $25 or less each, they look like this... http://www.a1electric.com/door_locks.htm and as stated you will need 2 SPDT relays and you wire them like this... http://www.the12volt.com/doorlocks/page3.asp#arp "Actuator/Reverse Polarity"

Or you can get a "Central Locking System" like this... http://spal.webprofessional.it...id=48 where the stock lock/unlock button or the key become the power door lock "button", [central locking] and they will have inputs for your alarm so you can have key-less. 94

 

thanks fcm. im guessing the actuators just have a power and a ground? are these actuators the ones i need? http://cgi.ebay.com/ebaymotors...ZWDVW

i got the wiring diagram and it has 2 lock/unlock wires one blue one green. i was wondering which is the primary wire so if you have it set like first click only drivers door unlocks second click passenger door.

Yes that is a "2 wire" actuator.
There is no "pos.(+)/neg.(-)" wire, they are both pos.(+) and neg.(-), they use a polarity reversing system to work, to lock one wire, [say green] is pos.(+) and the other, [blue] is neg.(-), to unlock it reverses the blue is pos.(+) and the green is neg.(-).
There are two ways to wire a polarity reversing system, ground at rest and 12V+ at rest, the diagram I linked is a ground at rest system, it means the way the relays are wired both the green and blue wires are grounded, when you arm the alarm one relay, [lock] is energized supplying one of the wires with 12V+, driving the door lock motor, [actuator] in one direction, when you disarm the alarm the other relay will be energized supplying 12V+ to the other wire driving the motor in the other direction.
Also, which wire is the "lock" wire and which is the "unlock" wire on the actuator will depend on what direction the actuator is "facing" in relation to the doors lock linkage. 94

 

ok i understand now thanks fcm.

now in the relay diagram you posted are the purple and blue leads just one actuator? or both drivers and passengers? im trying to see how with one output the the actuator it can both lock and unlock.

 

Yes, it is the wires from both actuators you can easily put 4 actuators off the 2 relays, all that is important is that all the "lock" wires are on the relay that is controlled by the alarms door lock output and the "unlock" wires are on the relay controlled by the alarms door unlock output, the wires can even be different colors, EG; front door actuators are mounted to "pull" the linkage to lock the doors and the back door actuators are mounted to "push" the linkage to lock the doors.
Remember, although there is only "one output" per relay, you only need one relay to supply the ground to the motors of both/all the actuators and one relay to supply the 12V+ to the motors of both/all the actuators, and as only one relay has to be energized at a time, [one for lock and the other for unlock] the relays are wired, in this case, to supply the ground to the actuators motors when the relay is not energized, [at rest] hence the name, "Ground At Rest Polarity Reversing System".
It can just as easily be done as a 12V+ At Rest Polarity Reversing System" where when both relays are "at rest", [not arming/disarming the alarm] both the wires going to the door lock actuator motors have 12V+ on them and the energized relay supplies the ground.
The only thing that would change is the wires that go to 87a and 87 on the relay, they would be reversed, [12V+ on 87a and ground on 87] 94


PS, this is a good read about relays... http://www.the12volt.com/relays/relays.asp

 

thanks fcm that was a good read. just one last thing does the length of wire matter? or can i just have the relays under the dash and run the 2 wires to each dorr for the positive and negative?

As long as the wire is the same gauge as the actuator or thicker you will be fine.
