DIY Vacuum/Boost Gauge Installation

[ezwong2002]

:)

I take no responsibility from failures.... :)

disconnect battery b4 doing wiring works... unless u are very sure of what u are doin.

Anybody interested to learn? if got.. i'll snap some procedures and pics :)

last time i wanted to learn how to install it... but since no body teach me i learn to pasang it with my friend.... here is the result.... no money to buy the bracket ... hehehe.... :D

 

[badguy]

yeah post the step by step to install!!!!!!!!!


BTW wat's the used of the vaccum meter????

 

[jinkl]

yeah got mine fixed also :)
but wiring i tapped from previos gauges la
+ - and ignition :D
the vacuum hose i just tarik from pcv hose la
ok we will wait for ezwongs pics :) sure can understand one

ya, i also want to know how to DIY install my Volt and Vacuum meter step by step, guide line are much more appreciate, thanks.

Difficulty Level : Easy-Moderate

Tools needed:

1. Screwdriver
2. Long Nose Plyer
3. Insulation Tape
4. Wire Cutter / Scissor
5. And any other tools helpful for the installation process (may include 2 sticks of ciggarates)
6. Multimeter to test for ignition 12V source (optional) remember to connect the batterty to test la... otherwise.. where got 12V when u turn the key to ON.. duhhh

1. decide where to mount your gauge.
2. look for possible spaces for the wires and or hoses to pass thru the dashboard
3. connect wires (any sufficient length to reach the fuse box)

 

[ezwong2002]

next.. locate your fuse box.. usually located in the right kick panel.. :)

picture attached is applicable for ATOS and Wiras

 

[ezwong2002]

next.. open the fuse box cover and locate the ignition 12V source.. from the fuse box.. i took the ciggie-lighter power source.. connect the gauge wire to the negative side of the fuse. follow the next pic..

 

[ezwong2002]

this is how i circle up the 12V power wires (from the gauge) together with the fuse.. (connect the wire to the negative side of the fuse....) so that the gauge is protected by the fuse.. if u connect to the wrong side.. it's not utilizing the fuse. if u can get what i mean... next is to connect the ground wire (from gauge) to the ground.. (car body ground can be accepted)

this wiring is applicable for autogauge smoked series only :) where we dun need to tap 12V source from the headlamp.. even so.. the headlamp powersource is usually located at the same fuse box in the drivers compartment or the engine bay fuse box.

 

[ezwong2002]

route the vacuum hose thru the firewall.. u can locate any possible holes thru...
i connected the vacuum source from the intake manifold to the stock fuel pressure regulator.. why? coz i can get steadier readings from that source. make sure the vacuum hose are not blocked or choked.. otherwise u wouldn't get an accurate reading.

 

[ezwong2002]

once u are done.. reconnect the battery if u have already disconnected it earlier... and test your gauge... this is an example how the gauge will look like when completed..


pic is for reference... however it has been replaced by a vacuum gauge..

anything unclear.. please feedback, i'll try my best to help :)

 

[ezwong2002]

samples of where u can mount gauges and stuffs....

[ezwong2002]

full view of the fuse box.. hahaha.. in japanese... damnnn

ezwong2002,
just curious after u tap the power source from the c.lighter fuse, then how can u close back the fuse casing cover because the gauge's wire is blocking the cover?
the vacuum hose connection for Wira, how?
then how about volt meter gauge installation?

one more thing, the fuse didn't indicate the polarity ler, how to know positive or negative?

 

[ezwong2002]

the wire only thin thin la wfc.. i still can close the fuse box cover..

vacuum connection to wira is the same as the ATOS.. see the intake manifold connected to the fuel pressure regulator... just add the 'T' to that connection lo..

yeah fuses don't have negative or positive.. but the connection in the fuse box got mah.. use multimeter la.. connect the -ve to body ground.. use the red probe to test the voltage from the fuse box lo... err... i really dunno how to explain in text.. however i can show u in real.. :lol:

p/s: poor in explaining in text... thats why i couldn't score all A's in my exams.. but practical.. no problemm...

 

[wfc31]

do u mean that the vacuum brake servo hose to the throttle?
don know the fuel pressure regulator ler.

 

[ezwong2002]

brake servo dun kacau.... urs is carb ah?

 

[wfc31]

ops, i get what u mean for the positive & negative liao, good explaination mar, don worry, give u "A".

nope, my Wira is EFi. u got picture shown the vacuum hose conncetion for Wira?

 

[ezwong2002]

not at the moment... but if u see.. the fuel pressure regulator.. is connected with the fuel rail.. in the end of it.. there will be a hose from the fpr to the intake manifold.. just tap that hose..
