In case you don't have one, the reverse light switch is a 2 pin connector right in front of the battery. It is on the top of the transmission. I believe it's some sort of -4 or -6 AN fitting, because I noticed it's the same thread and diameter as the ports on my Aeromotive regulator, which was the same as my old S-FMU. You can get to it without taking the battery out, but you will probably have to take off the intake pipe.
