I have a 99 Ram 2500 with factory keyless entry that I have installed a Prestige by Audiovox remote start and keyless entry.  I've done about 3 of these installs before.  The remote start works fine, but I can't figure out the doorlocks.  I've locate the wires at the factory keyless unit, my wire diagram says they are poisitive switch.  No matter what I do, I can't get  it to work, please help.

thanks

-Jeff

Ok looking over that diagram, it makes perfect sense... I'll have to try it first thing in the morning.  I can see now why if I applied power to one terminal it would kick the lock back... because the switch wasn't disconnected......... the 5 wire relay does that and... wow thanks for the help, I'll let you know how it turns out.

Notes:
Note : Diesel glow plug wire is a ORANGE / black(-) "see direct fax document #1090", and the tach wire is a gray/black. Both wires are located on the center of the firewall. There are two black plugs, the wires are in the top plug without the white insert.  *1 Keyless models use positive trigger for lock, and 5-wire for unlock. Can also find wires at the central timer module to the right side of the steering column, lock is ORANGE / green, unlock is pink/green.  *2 To avoid dome delay, use tan for the drivers door and BLACK/ lt. blue for the passenger door.  Both wires are located at the central timer module to the right side of the steering column.  Use both wires and diode isolate each.  *3 Must see a ground on the tan drivers door trigger wire while locking to arm the factory alarm. This only works if the vehicle does not have delayed domelight.  *4  Diesel tach wire is gray/black at the ECM on the passenger side firewall in connector C-1, pin 8  *5 This wire requires a high current negative, must use relay.
