I just finished installing an Audiovox model APS 785 Security System in my 95 Powerstroke Diesel truck (Automatic Trans). Everything seems to be working fine though I have not as yet tested the remote start feature. My main concern is the wiring of the power door locks, I have the 5 wire reverse polarity connection which I have no instructions in my manual for. I installed two 5 pin relays as described in this forum in another post......... My security system module has 3 wire feed to control these relays, the first wire red will pulse ground for lock and 12V+ for unlock, The second wire green will pulse 12V+ for lock and ground for unlock, the third wire red/blk will pulse ground only for secondary unlock (all other doors).
My relay connection call for ground pulse only from the security module on both relays to activate either lock or unlock. Here's what I did.... Red wire to lock relay and green wire to unlock relay. So when I press lock on my remote control the red wire sends a ground pulse to the relay, doors then lock.... When I press unlock green wire sends ground pulse to relay, doors unlock, seems to work fine....... But meanwhile when the ground pulse is being sent out to either relay the opposite relay is getting a 12V+ pulse, wich means 12V+ current flowing in from both ends of the relay coil..... This will not activate the coil but My question is, Will it damage the coil or locking mechanism in anyway in the future?? .......... Does anyone know if this will continue to work as is or does anyone have alternative wiring instructions??.
I hope this post is not totally confusing to everyone, just looking for a better idea......Thanks.

 

12 volts on both ends of the relay coil will not hurt it. In reality it sees zero volts in this situation.

 

Thanks for the response Franklin2. .. I felt that it would do no damage either but Im no expert and I needed a second opinion ........ Im gonna leave it as is, I do appreciate the reply.
