I'm still planning on running a ground to the engine bay to ensure it is solid. Does anyone have an opinion on this? I'm installing Autometer electric oil and temp.
Someone above said it's alright to pull the 12v and lights from your radio harness. I'm still planning on running a ground to the engine bay to ensure it is solid. Does anyone have an opinion on this? I'm installing Autometer electric oil and temp.
i used the 12v switched from the radio harness, as well as the light wire, and used the same under-dash ground screw when i did mine. works well enough.
