installing in a Mercedes sprinter
does anyone know where this wire goes to for the indicators to flash.
White/red light flash input - this wire is the input for the on-board dual light flash relay. if the vehicle has positive parking light activation wires, connect this wire to a constant (+) 12v source that is fused at 15a or higher (if the vehicle parking light activation wire is negative, connect this wire to a chassis ground.
if I put it to the positive to the indicators
then where do I put the two white wires
white parking light output - these wires are output of an on-board dual make relay and should be connected to wires in the vehicle that control the parking light wire polarity. if the vehicle's parking lights are controlled by a single wire connect both white wires.
thanks for the help.
