Smoke face boost gauge wiring

[SLIPPERY]

hi, just wondering if anyone can help me here

ive got three wires to connect for the boost gauge

they are:

12V ignition

12V lighting and

Ground

now, just wondering which wires i should splice into for all three ???

the car is a ser1 r33 gts-t....im unsure of what wire goes where

if anyone has pics thatd be excellent

thanks

Splice your 12v lighting to the ciggeret lighter light. and the ground to your chasse somewhere. Dont know about the 12v ignition though???

[SLIPPERY]

wouldnt the ciggy lighter only have power when the lights are one?? whereas, with the smoke face, i need light constantly.

hmmm

[GunMetalR33]

My guess is that the 12V ignition is for the costant light to light up the smoke face. Then when you turn on your lights the 12V lighting (connected to the ciggy light ie, accesories) makes the boost gauge light up even more as it is now dark out side and the constant 12V ignition lighting is not enough.

Just a guess dude, dont take what I say as bible.... Hope this helps.

[SLIPPERY]

well i sorted it out anyway

i connected them to the stereo cause i had the wiring diagram for the deck and it had the 12v ignition and 12v constant power that i needed

thanks for your help!

I would be carefull using constant power becuase you only want the light to be on when the car is on right...

can someone help me out i have a TIMEX smoked boost gauge with 3 wires

black, yellow, red

the instructions are crap and don't mention which color is for what

i'd assume: Black = ground

Yellow = lighting or ignition

Red = lighting or ignition

can someone help me out how to find out which is which

also what is the best way to connect the pressure hose. there isn't much holding the hose in and it would leak if under a lot of pressure. any ideas on how to fix this?

anyone got any ideas on this?

zip ties

and as for the wiring, don't quote me but i *think* that:

red = +12V constant

black = GND

yellow = +12V Accessories

but this could be worng. i have a timex oil temp and the yellow wire for that is the sensor wire from memory :confused: but i'm assumiong that it's a mechanical boost guage?

[GunMetalR33]

I think the australian standard is as below. I cant think why your gauge new need const power though? Does it have any memory features?

If its a eletronic boost gauge (ie comes with a MAP sensor) then it should work as follows:

yellow => 12v Accessories

Red => must be to the MAP Sensor

Black => Almost certainly be ground

If that does not work swap the yellow & red wires.

If its a mechanical job then:

yellow => 12v Accessories

Red => must be const (for memory features)

Black => Almost certainly be ground

The Timex gauges don't have memory features. My oil temp guage needed 12V constant from memory and I still have no idea why it needs it?

My best guess says it's this one:

yellow => 12v Accessories

Red => must be const (for memory features)

Black => Almost certainly be ground

the guy said it was electrical but i don't fully understand the difference...it still has a place for the pressure tube to go in...so how is that different to mechanical.

i'd assume it has constant power...because it's smoke faced...eg hard to read without a back light.

and the accessorie light is for when it's night time and needs to be brighter i guess.

[46n2]

if it's got a tube to attach a hose then it's mechanical.

[Restless 33]

jsut thought i'd post some pics of the gauge to help out...

wats the difference between mech and electrical btw?

the parts picture shows a nylon tube (white) and small black rubber tube, pressure nozzle, two tiny things that look like /

........................................ /

(ignore the dots)

and also a screw that looks like |_| with a whole in the bottom for the white pressure hose to fit through...

the hose fits bit could be pulled out easily...eg if underpressure.

any ideas

thansk for the replys guys

[GunMetalR33]

It might not be mechanical: It sounds to me like the MAP sensor might be in the guage it self (I know it sounds stupid but it fits the facts). This means that you need the tube in the back for the MAP sensor, const power for the MAP sensor (red), acc for the light (yellow) and ground (black).

if it's got a tube to attach a hose then it's mechanical.

[GunMetalR33]

As for the pressure hose:

You need a little "nipple" like thing on the end of the hose that goes into the gauge. Then when you do the bolt up it gets a little crushed and forms a seal. Go to autoBarn or some place like that and they will show you what I mean, you can get these parts there too.

pictures are now up ^^^^

the nipple things aren't the little gold things in the pic with all the parts??

[Restless 33]

also do u hook up electrical the same as mechanical? where do u get the MAP reading from?

[GunMetalR33]

Yea, thats them. It looks like your hose is to fat to use them though :{

That yellow wire is const for sure!

Here is another theory, it may be the case that it is setup to be either electrical or mechanical ???

The MAP reading has to come from a MAP sensor. R33's have them for the stock boost gauge near the speedo but they are only good to read about 1 bar I think.

also do u hook up electrical the same as mechanical? where do u get the MAP reading from?
