Hooking up reverse lights

If the left switch is towards the rear, then that is one spec'd in the instructions; the instructions pretty clearly illustrate the reverse light connected to the left pair; see figure 8 on page 13. The test Crackedback outlined above should confirm this for you.

The left pair and right pair of contacts each is to a separate microswitch; there are 2 microswitches stacked back-to-back. The right pair is for the NSS.
