Hi, I will soon be installing a set of driving lights on the Aluminess front bumper on my 2013 NVP 3500. My plan was to hook them up so that they turn on when I put on the high beam headlights. From looking at the wiring diagrams, it appears to be more difficult than just tapping into the high beam relay to get a trigger for the driving light relay. The headlight relays for this vehicle appear to be non-replaceable and mounted on a circuit board, which makes them basically inaccessible for accessory wiring. So, I was wondering if anybody has hooked up auxilary lights to the NV factory lighting system and how they did it? At last resort, I will just install an accessory switch and trigger the driving light relays that way. thanks, Pete Fazio
