Help installing boost gauge
- Thread starter Wardie77
- Start date
i would wire from the radio harness. you can run from the interior dimmer circuit or illuminate when the car is running.
from what ive found laying around:
function --- gauge wire color --- protege wire color
+12V ------- red ------------------ blue/red
ground ------ black --------------- black (or ground to any unpainted metal)
amber ------- orange --------------- light green/black (for dimmer circuit)
lighting ----------------------------- pink/black (for on when car is on)
white lighting is similar to amber lighting, if youd rather have that just use the white wire instead of the orange one.

I hate my prosport gauge. If you wire it up to be amber at night and turn your lights on too fast it might not be amber all the time. I kept thinking it was a faulty connection but Ken from protege garage said if you turn them on right after you start your car you will get that problem. If I ever get the money DEFI here I come.
turn on your lights slower...? lol
i'm prob going to get the autometer boost gauge and prosport for wideband, oil temp and pressure.
the boost gauge will be mounted with ForceFeds steering column pod

i like this one since i won't be boosting over 10 anyway, then the needle moves more

There ya go, just in case you didn't catch it. If you turn on your lights right after you start your car they wont be amber all the time, to make this even more simple.
EX. if you turn the lights on a couple seconds after the car has been started then one of the prosport gauges (I have two) might be white and the other be amber or they will both be white, when they are both suppose to be amber.
By "too fast" I mean right after the car has been started.

Yeah, Im one of those jump in and run type of people lol.
haha you make it sound like you're robbing banks.
anyways i dont own these gauges but im considering it down the road... im just confused as to how you have them wired right now.
you have both the white and amber wires running to your headlight/dimmer circuit? if so what would happen if you disconnect the white wire... they might not glow at all? and if its not wired like that, how do you have it wired (i.e. white on the ACC circuit and amber on the dimmer?)

They are wired correct, I am 100 percent sure. I have them wired up to be white during the day and amber at night.
i'm bored. here's a relay diagram.
again i dont know for sure how the gauge switches from white to amber, but the relay uses the ACC circuit for white and when the headlights are on switches it to amber.
assuming the gauges are switched, only the amber would be active and it (hopefully) wouldn't be confused.
also if you want you can connect multiple gauges in parallel to the relay. only one connection to ACC, the dimmer, and ground is required.

What would installing a relay do?
only power the white or the amber wire.
if the lighting works only half the time, id imagine theyre switched internally, i.e. if it detects more than 13 volts on the amber wire it changes over.
so if you switch them on right after you start the car, its a crap shoot as to whether they turn on since the car isnt up to voltage. this might not be the exact scenario but id imagine its similar.
the relay would power the white wire when the headlights are off and would switch the power to the orange wire when the headlights are on. this prevents the gauge from "guessing" which backlighting to power since only one wire is powered at a time.
it should solve the issue. something youd try?

yeah for sure. What relay do i need?
