I have a 07 peterbilt 379 I’m having electrical issues with. I replaced my headlights with leds and they now stay on with the switch odd and even with the key switch off. I’m getting 7-9v all the time at the plug, even with the low and high fuses pulled. I don’t think this was an issue when I switched headlights but maybe I never noticed with a regular incandescent bulb, not enough volts to power up those bulbs?
Anyways I’m looking for a wiring schematic and/or some advice where to start looking. My vin is 1XP5DB9X17D686167
