The backup light switch (arrow) is on the driver side of the transmission, up near the shifter. We ended up splicing into it by soldering wires to it. Do yourself a favor and scour junkyards for the male side of the plug off another Chrysler or later-model Mercedes vehicle. Another thing you might want to do, if you do solder wires to the switch, is do it before the transmission is in the vehicle.
