im putting the the boost gauge today (i know ive asked a lot)
all went well except when im doing the back lights on the gauge.

i have a add a circuit and i plug it in the #37 fuse (dash lights)

when i plug it in the light on the gauge works but the dash lights wont.
ive tried different fuse. ive directly plugged in the gauge with out the add a circuit and same thing happens.

here is them both off



here is when the boost gauge is connected with the add a circuit



here is when only the dash is connected



and here is how i connected the 12v and ground of the boost gauge in the fuse box



any tips?

bad connection or fuse in the add-a circuit, Dumb ?, do you have 2 fuses in the add a circuit?

do you have the light switch pulled out? the fuse should have constant power

[crappy_head]

yeah i got them both in and changed them out for other ones just to see if it was that.

a test light can be a big help,they are cheap too.

[crappy_head]

yeah im going to get one tomorrow.
im open ears for anything else, like if i can use another fuse number o somewhere else in the fuse box

I used the dimmer wire that went to the radio,don't remember what color it was thou, you can also hook it to the headlight switch

I know it's no help but your gauges look amazingly beautiful =)

not sure on exact set up, but i am willing to pitch an idea. the gage cluster should have its own hook up, like in the 3rd pic. if thats the way its suppose to be, then leave it like that. the boost gage, hook up on its own wiring. run a ground independant, hook power to 12+ accessory wire from main harness, and dimmer off the switch if applicable.

good place to start

[crappy_head]

im still having trouble.
i found 12v in the radio but its not dimming.
i took out the cluster but nothings labeled.
anybody knows which one is 12v w/ dimming?

the wire to radio is not a dimming wire,use that wire if you want the guage light to come on with headlights and that wire is located above your right
knee behind/under dash.(light blue/red stripe) It was easiest to acess. if you want to dim, then splice into back of headlight switch(dark blue with white stripe)

mother f'er

it was the add a fuse. the old one was brand new. thats why i never thought i was that. i took apart half of the interior, lost a day off and got really pissed for nothing!!!
bought a new one and it works like a charm now.

you told me in your first post limited, but i never thougt it was going to be the add a fuse cuz it was new. thanks!

[SWEET2KSTANG]

the accessory wire is off the main harness that comes from the column. i amtrying to find my wire diagrams to get color. you can run the dimmer off the switch, i think its the white wire if i remember right.

[crappy_head]

thanks sweet but i was a shitty add a circuit. got a new one and now it works fine with dimming!

[SWEET2KSTANG]

glad you got it fix't

still put a test light on the "to get" list. They are cheap and you would have found your problem quickly
