aftermarket gauge install
okay so i ordered a boost gauge from glowshift and i dont know where to connect the power and light source wire... i know i could run the power wire straight to the battery but i dont wanna have a cluster of wires that lead to the battery, its just cheesy.... and the yellow wire needs to be connected to a light source that will come on whenever the headlights are turned on. also the actually hose that measures boost from a vaccuum source, where did you install the t-fitting for it????.. please help!
Couldn’t you wire it to the headlight switch? I think its a yellow cable with a black tracer. Just take out the headlight switch, turn it on/off while testing multiple wires with a wire tester to find the one that goes on/off with the switch but I think its yellow with a black stripe. Search for how to install reverse glow gauges and wire it up the same way.
