    Installing Oil Pressure Gauge - Which fuse to tap into for light?

    Hi All -
    I'm installing a new mechanical oil pressure gauge this weekend and want to tap into the correct fuse so it lights up when I turn on the headlights / dash lights - would love some insight on which would be best to use. I was going to do the headlights, but was thinking this may have continuous power and is actually not good choice? Any help would be appreciated! EDIT - it's a 12V gauge light.

    If you want the gauge to illuminate when you turn on the lights and you want to access that power from the fuse box, then tying into the tail lamp circuit might be the easiest solution.

    Great - thank you. I'll give it a shot, otherwise I was just going to go into the cig and have it lit all the time.

    I just did an electronic op gauge I used add a circuit basically gives you a wire off an existing fuse then you get another wire coming off it with a dedicated fuse fast and easy and if you ever want it gone or it dies on you pull the fuse and it will be just how it was.cost $5

    Yep - that's the plan. Which fuse did you use?

    I used the ignition fuse but I wanted mine lit up all the time I. The ignition fuse slot was better with the add a fuse because the fuse slot below it is empty more room for it. Don't know what kind of gauge you got but mine came with an extra wire on it to tie into the dash lights so if you want it will dim with the dash dimmer wheel.Name:  IMG_3254.jpg
