(A single output connected to multiple relays will allow you to open continuity and/or close continuity simultaneously on multiple wires.)
I installed an avital 2200 and I will be adding door actuators(door locks), but wiring the relays is a bit confusing when adding 2 doors.
The manual shows two relays for one actuator. My question is how to split the 12 volt power and how to split the lock and unlock wire across 4 relays as well as putting the fuse(s) in place.
After this I should be good to go.. I wont be adding anything else onto the system.
Thanks in advance. ------------- AJM

If you are installing aftermarket actuators, they should have a green wire and a blue wire on each actuator. Mount the actuators and run the wires to the alarm system. Connect all blue wires to the blue wire from the alarm. Connect all green wires to the green wire of the alarm. Page 11 in the manual you linked to.

What about the Second Unlock Output? Above is what I envision.. Just want to make sure it is right before I spend another day wiring this up. Page 14 shows I need Relays, not just a direct wiring. I want to utilize the second push of the unlock to activate the passenger door. ------------- AJM

You don't need 4 relays, 2 will cover all 4 doors, factory actuators draw about 3-6amps, aftermarket 5-7amps, thus one rlay for each direction is adequate for 4 doors, you will need a third relay only for priority unlock for the driver's door which to my mind is a bit paranoid.

So does this look right? ------------- AJM

Keep in mind.. I am doing driver and passenger door actuators only.. not all four doors.. I wanted to utilize the double push on the remote to unlock the passenger side and driver side... vs. one push unlocking the drivers side lock only.

Your last post rather confused me, the normal procedure as on factory locks is to lock all doors then the first press on the disarm/unlock button does the driver's dor, 2nd press other. any way my graphics are lousey so here's how you do it. Alarm lock green or GREEN/ black model dependant 85 on relay 1. 12v+ to 86 and 87 on all 3 relays. Fused at 15amps. Ground to 87a on all 3 relays. Lock output to actuators on both doors 30 on relay 1 Alarm unlock blue or blue/black depending on model to 85 on relay 2 Unlock output from relay 2 30 to driver's door actuator Alarm 2nd unlock wire to 85 on relay 3 Unlock output from relay 2 30 to passenger door actuator. There, it's that simple. To wear a belt and braces, for technical reasons wire diodes across the coil terminals 85 and 86 with the bands towards 86.

Okay, so here is what I got out of that last post.. Thank You sooooo much!! I am a visual person... well.. I am male.. and I have a cool app that helps me draw really cool graphics for the next person who decides that their 90's model corolla needs some upgrades. :) PS. I put diodes in the drawing, hope you can see them.. Question on that: Im guessing that I just bridge the diode and it will look like this.. see pic below:

Absolutely correct, now tell me about your graphics app because I'm getting frustrated with having to "talk" these things out!
