Yes please show me how you did this so as not to send 24 volts.... Parallel?YES .... My aftermarket b/u lights are wired so they come on with the stock backup lights or when I hit Aux 3. I tapped into the reverse wire on the tow package, 7 pin connector. I also ran a wire up to Aux 3 in the engine bay. This set-up necessitates the use of 2 diodes.
P.S. still enjoying my Tazer... thinking of putting in front camera as well. Thanks for stretching me....
