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 :happy: I know nothing about wiring (im at the point where i need pictures of what i need to tap / wire up)

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

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

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 ...

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...

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

    • It is a kunfine Android screen . Does anyone know the wirering diagram of the fuga ??
    • just an update to this, poor man pays twice  Tried sanding down the pulleys but it didnt do the trick. Chucked another second hand alternator in the na car which I got for free off my mate and its fixed the squelling. Must have been unlucky with the bearings.    As for my turbo car, I managed to pick up a cwc rb alternator conversion bracket + LS alternator for 250 off marketplace, looked to be in really good nick. Installed it , started the car and its not charging the battery.... ( Im not good with auto elec stuff so im not sure if this was all I needed to do but I verified such by using a multimeter on the battery when the engine was running and I was only getting 12.2v )   I had to modify the earth strap for the new LS alternator , factory earth strap was a 10mm bolt which did not fit the bolt on the LS alternator which was double the size so I cut it off , went to repco bought some ring terminals that fit, crimped it onto the old earth strap and bolted it up to the alternator , started the car and same issue. Ran like shit and was reading 12.2 at the battery.  For a "plug and play" advertised kit thats not very plug and play but alas.  My question is , am I missing something ? Ive been reading that some people recommend upgrading the stock 80 amp alternator fuse to a 140 amp but I dont see how that would stop the alternator charging especially at idle not under load.  Regardless ive pulled it out and am going to get it bench tested by an auto elec tomorrow but it would be handy to know if ive missed something silly or have done something wrong.   
    • My wild guess is that you have popped off an intake pipe....check all of the hoses between the turbo and the throttle for splits or loose clamps.
    • Awesome, thanks for sharing!
    • To provide more specific help, more information is needed. What Android screen? What is its wiring diagram? Does the car's wiring have power at any required BAT and ACC wires, and is the loom's earth good?
