Iím installing an Avital 3100LX alarm and am trying to get the keyless entry working. My van has reverse polarity locks and Iím 80% sure I need a relay so I bought one and connected it to the passenger kick panel red and brown wires.

I currently have white and black wire connected to red lock wire leading to door.
Green wire connected to red lock wire leading to engine.
Brown wire connected to brown unlock wire leading to door.
Blue wire connected to brown unlock wire leading to engine.

Iíve tried purple wire grounded and to constant 12v and still doesnít work. The lock and unlock buttons on the door work, but the key fob does not. I hear the relay clicking but it doesnít affect the locks. Iím at such a loss. I tried even reversing the wires, white and brown leading to the engine and nothing.

What am I doing wrong?

the 451m for five wire would be
white/black   brown lock wire going toward the switch
green/black   brown lock wire going away from the switch

brown/black red wire going towards the switch
blue/black   red wire going away from the switch

purple and the purple/black wire to a +12 constant

If it came with a factory key fob for keyless entry
purple and purple/black to +12 constant
white/black and brown/black not used

green/black - should be a pink/yellow and a pinky/green @ passenger switch, need to test but should show + when you hit lock or unlock, does not says which is which
blue/black - should be a pink/yellow and a pinky/green @ passenger switch, need to test but should show + when you hit lock or unlock, does not says which is which
