[josephg15]

hi there i am doing my swap today and i dont know which wire to tap into for my boost gauge...does any one know which one to tap into at the ecu (its the JDM ecu) what is the color...? thanks

what kind of boost gauge do you have?

[drifter_for_life06]

why would you tap into the ECU?

pressure line

and a power and fround if it lights up should be all you need

for my automemter gauge the pressure line is t-fitted into the fuel pressure regulator vaccum line, grounded to a bolt by the shifter and it gets its power from the radio

any electrical wiring on a boost gauge is more than likely for the lighting. you need to ground it,black wire, and connect the lighting to a wire connected to anything that is lit when you turn you headlamps or parking lights on. Everything else should be hoses. If this doesnt make sense go out for a drive and find someone with a fart tip...they can do it!
