2001 Dodge Ram 1500 Door Locks

Depending on whether or not the truck origionally had keyless entry, the lock wire may be a five wire (reverse polarity) setup.  If you are using a 451m  you should not need any resistors or diodes to get the locks working.  I would find the unlock wire and cut it, then connect the BROWN / black from the 451m to the switch side of that wire.  (the side of the wire that reads 12v when you hit the unlock with the switch).  The blue/black (451m)gets connected to the other side of the pink/purple wire (from the truck).  Then I would locate the lock wire, and with a 1amp fuse in line, i would feed 12v into the ORANGE / purple (lock) wire.  if it locks...just hook up the GREEN/ black wire to that wire without cutting it...if not, its reversing polarity and you will have to cut it like you did the unlock wire.  Then connect the WHITE/ black wire (451m) to the switch side of the cut ORANGE / purple (truck) wire.  connect the GREEN/ blk wire to the other side of the ORANGE / purple and then put 12v constant to the two purple wires coming out of the 451m.  make sure all of your fuses are good...and you locks should work fine...assuming that the small guage green and blue wires are connected correctly at the brain.

I mean fun!!

They are fun but the 451M is a great product... I'm glad DEI made it.~The Rookie~
