I received my boost gauge today but I'm having a lot of trouble installing it.

I've taken the hose that connects from the throttle body to the boost sensor, out of the boost sensor and put my T piece there. I have a short hose connecting the T-piece back to the sensor and the last hose attached to the T-piece is the one that runs to the gauge. The hose supplied to me had a larger diameter than the hole drilled into the back of the gauge, so i carefully used a screwdriver and incresed its diameter so that the hose fits tightly inside.

Now... if I have done anything wrong so far, let me know.

For the electricals... I got really confused. I don't have a screwdriver long enough to reach up into the steering wheel column and get the 4 screws that require a pretty thin and long neck lol. SO what i decided to TRY to do was connect it through the fuse box under the bonnet. I tried putting the red wire (manual says it's supposed to go to ignition (12V)) to the 30A "ignition" fuse and grounded the gauge on a bolt on the chasis inside the car.

When i turn on the car, i hear a lot of air going into the gauge through the house, but when i increase the throttle, the gauge doesn't work :(

Please help!!

P.S there are 2 other wires on the gauge harness (yellow one = standard ignition, white one = ignition light?)

I don't have a multimeter so I can't test what wire is active when the car is on, or when the lights are turned on.. but i can always tap into the cigarette lighter light i guess.

There shouldn't just be a "hole" in the back of the gauge, there should be a nipple to put the hose onto and you shouldn't hear any air.

That's a leak. Do you have a pic of the back of the gauge?

Power for the gauge is easier to get from the cig lighter itself and light it off the cig light.

LOL. You are gonna have to connect the sensor too!

You have bought an electronic Boost gauge. The sensor has the hose go to it and it sends the signal to the gauge.

(just like the stock gauge).

A mechanical Boost gauge has the hose go straight into it. no sensor.

But the gauge i bought is mechanical, it isn't electronic :\

this is the ebay link to it

lol, oh man i'm so confused now...

HMM ok, but the sensor only has one nipple on it. How am i supposed to attach the hose from the T, and then attach another hose to the gauge if there isn't anywhere to run the hose from? lol

The sensor comes with a wiring loom, hopefully i don't run into trouble hooking that up..

no hose goes to the gauge, from what i see, hose goes from t to the sensor, then one plug goes into the sensor, and another into the back of the gauge, then the wires are wired up to the car... thats what it looks like

Got it installed today! wiring was a bit all over the place lol, but done in the end. I'm not sure about its accuracy because it's basically reading the same (but showing im boosting a bit less) than stock.

Need to find a trusted gauge to calibrate it next to lol.

cheers for the info guys.

P.S is it just me, but whenever i'm working on my car taking stuff apart and putting new stuff in, something that was in my hand 2mins ago just goes missing for like the next 10mins? lol

sorry to bring this thread alive again, but it's regarding the guage. it works fine and everything, but the one thing i didn't get time to hook up was the light switch wire.

So i tried hooking it up today and tapped into the cigarette lighter light, so that the backlight of the gauge would only turn on when my headlights are on.

HOWEVER, for some reason when i turn on the light (one click to turn the parker lights and interior dash lights on), the fuse blows up!

The 10A fuse underneath the bonnet that's labelled on the fuse box cover as "Head L RH" keeps blowing up. I've replaced it 4 times now, and i don't know why it's doing that :( Shouldn't tapping into the cigarette lighter light work? :s

P.S I've tried opening up the steering wheel column and finding a wire to tap into when the light is switched on, but the looms are crazy tight and i can't access any wires.

Have you tried putting an ammeter in the circuit to the gauge's lighting wire to see what current it is drawing when you give it 12V? It might be drawing an enormous current due to being f**ked.

no i haven't tried that. That would explain it though... if the amps are too high, would soldering a few resistors together fix it up?

    • We have 2x Swifts and my plans for a Swift, unfortunately, do not extend to an intake and an exhaust. I've been having dirty thoughts about a 2.5L Suzi V6, AWD gearbag out of a suitable donor, rear floorpan graft to take the rear cradle from same, and either trumpets of evil or a small supercharger. If I'm going to make noise in a Swift, I want it to be anti-social, evil handling and rough. Probably need to be fully stripped inside, matt black paint, plastic windows, 7" wide wheels, big brakes, silly suspension, etc etc etc. I have no idea if any of the proposed driveline components could take the pain. But it would be a hoot finding out.
    • Really, anyone modifying a car isn't being financially smart. We're doing it for the things we love. And honestly, a high revving, light, NA car is actually pretty darn fun. I used to have a Swift Sport, and I miss that thing as a daily, and yes, doing something like some intake and exhaust stuff would have made minimal gains, but would have bought an even bigger smile
