what do you need to know?
because of the cost of the harness for the St170/02+ and the lack of availability of the pig tail connectors, we use, 1/8" spades connectors, some heat shrink and a little silicone. obviously not the prettiest way of going but we have used this method for years without problems or wiring issues.
as for the rears...
for the reverse light you just need to splice into the reverse lamp wire and run a wire to the rev lamp and then a common ground to body or back into the taillight harness.
for the rev-fog you will need to run a wire back from the headlight switch off the front foglight harness to the rev-fog and then to a common ground on the body. we suggest you run 2 wires at the same time incase you ever upgrade to the european tails which you will need the extra wire for the brake lamp.
