Hello all. Wondering if the havoc has a prewired back up/reverse shift connection? My friends Honda pioneer 1000 did and is was very simple to put in a reverse shift light. Just mount the light then connect to the prewire.
The only way to have a reverse light come on automatically is by purchasing a decoder box to decode the signal coming from the transmission range potentiometer. I bought a Dakota Digital decoder box and wired it up and have a reverse light that comes on when shifted into reverse.
