I'm installing a prosports oil temp and it needs me to tap the headlights wire. Has anyone installed this before? If so can u please tell me where you tapped it at, or if u used an add-a-circuit, where did u place
it at? Thanks and merry Christmas

 

Why don't you tep it into the headlight wire like it says? anywhere on the wiring that goes from the headlight switch to the headlight will work fine, if thats what your asking

All it's using that wire for is to turn on the backlight of the gauge when you turn the headlights on
