i have a 99-00 ex, and i'm tryin to wire up my boost gauage. i already have the boost vaccum lines hooked up. the only problem i'm having is that i dunno which wire goes to which wire under the steering wheel, to hook it up to so that the light in the gauge turns on when i turn my lights on. i have a faze boost gauge. any help ?

 

My way might be considered hack, but i just ran the wire to the driver side parking light fuse. Works good for me.

 

if you got a harness for your radio you can run the light wire to the harness.for honda it should be the orange wire that says illumination.it only comes on when you turn on your headlight.try that

 

get a test light or a test meter for this, but the Radio Harness will also work,


you need to find the ignition wire,

 

ignition harness is i think to much to play for boost guage.the only time you need to go there is duing turbo timer installation.either the fuse box like ramma mention or the steroe harness for easy access.

 

thank you for your help guys. i will try the radio harness wire
