Boost Gauge Install

[defari]

so after my boost gauge has been sitting on my desk collecting dust for a few months i decided i'd have a shot..

after about 5 hours googling, trolling forums etc etc i still cant work it out (i have no electrical knowledge at all) and im not paying someone $100+ for something that probably takes 30 mins to do.. (yes ive rung sooo many auto electricians, cheapest was $100/hr)

questions

1. seeing as i have 3 greddy gauges, can i tap the wires from that (ground, power etc?) The Greddy gauges have the same wiring as the "autogauge" boost gauge.

2. If im able to tap those wires, all i then need to do is tpiece the vacuum line, mount the gauge, thats it right?

apologies for yet another "boost gauge" thread I know nothing about wiring (im at the point where i need pictures of what i need to tap / wire up)

sounds like your on the right track there mate. im not an electrician, but my dad is =P

**i take no liability in saying this** =)

hey mate where are you located? if you have a greddy slim series you dont need to wire it in they use power off the exsisting gauges.. if your close to mt gravatt i'll give you a hand wiring it in if you want ... simple really hardest part is mounting it lol

yeah as above, just use hook it in to the existing wires

im over in paddington / ashgrove area. I think mine are the slim series like the one attached except i only have water temp, oil temp, oil pressure. Not sure what you mean, i dont need to wire my gauge in it uses power off the existing gauges? (how does it get power without wiring in?) or do u mean is the boost gauge a Greddy slim series gauge?

did a mock install before i tried it

photo below, the 2 top bits (the wiring and the filter thing, i have no idea where the filter goes, and i think the wiring is just extra incase you want to have a warning light)

pic below is where one of my Greddy gauges is already wired up, black, red and white wire (this was my reason for the topic, can i tap those three wires?)

pic below is apparently the vacuum line (which runs into the black unit which is the stock boost sensor for the stock boost gauge which is right behind the drivers side strut tower)

anyone know if im on the right track?

first pic.. those ms paint bits you added to ask questions.. even on 400% zoom i couldn't even make out what you wrote..

why don't you get power off the ciggy lighter or something inside your dash that uses power when the car is started.. that way your not taking lines all the way to the engine..

if you got a factory vacuum line.. are you still using the factory boost gauge? if not then use that instead of the line with your gauge.. if you are then just cut into it and install that tee (one you circled

[defari]

cheers mate, yeah sorry bout the pics / ms paint

sweet, gonna have a crack at this now.

3 hours later and i still cant work it out..

ah ok its a auto gauge.. well its better if you run the 12V acc power off your stereo , earth it either near the fuse box the bolts that hold the bonnet opener , one connects to your illumination (dims itself at nite) , the other is constant 12V this can be used from your stereo , you can earth it using the steel caddy around the headunit ...

[defari]

i think my dimmer light or connection is buggered.. my 3 other gauges dont light up (never have), the dash stays the same brightness, for some reason now my antenna doesnt work..

take +ve from the cigarette lighter

-ve to chassis under gear boot

Tee the vac line at the factory MAP sensor to the left of the brake booster

[defari]

cheers mate for the help but i have no idea where that is.. theres a billion pipes / tubes / wires, unfortunately i need pictures of exactly what your talking about

[53XYN]

by the way just to let you know you shouldnt tap into the Greedy sensor wires as that will stuff your gauge reading .. thats mainly for the sensor to convert it from analog (vaccum) to digital pressure for the gauge to read...

[.:: GimpS-R34 ::.]

why don't you mount the gauge.. hook up the +ve -ve etc wires that you know where they go.. then try bribe a workshop to hook up the last bit for cheap.. tht way you've done most of the work and they make a quick $$$ for little effort

[53XYN]

hey mate if your willn to drive up to my hosue i'll hook it up for you in 30 mins .... pm me if keen

[Lazy-Bastard]

if you look between the brake booster and the guard on the drivers side you will see a small black plastic box (MAP sensor) with a vac line that runs to the inlet plenum, tee into that

see you sat bud !

[defari]

Massive massive massive thanks to Vish for installing my gauge today! Absolute champion. Couldnt stop admiring the v35, that thing is a beast!
