Older HKS gauge install

[92SupraMan]

I feel kinda stupid posting this up, but after calling HKS and searching the web I have come up with nothing.

Any one know how this boost gauge is supposed to be wired in? I would have figured 2 powers and a ground, but theres more going on that I anticipated.

 

[NDBoost]

it looks like its an electronic boost gauge maybe. Do you have the sensor for it?

 

[92SupraMan]

Yes, I have everything for it, my question is what wire is what...

 

[92turbo4life]

that gauge is simalur to the one i have in my 92 but mine is in the cig lighter
pm drjonez and he can tell you. he installed mine

-Warning Output
-12v when igition is on
-2 for Dimmer/Lighting
-Ground
-Sensor Wire

not sure which are which lol. Theres tons of reference out there for greddy stuff but never for hks. They suck at documentation

 

[92SupraMan]

Yeah I agree, not even the guys at HKS could tell me anything other than "try supra guys, they run those old gauges"....:icon_roll

My best guess so far

red: 12v ign
yellow: warning
Black: ground
Orange: 12v constant
Green: ?
Gray: ?
Brown: ?

And the sensor has a plug so I cant screw that one up, and thats why its not pictured.

Too bad you can't experiment you could fry the gauge though.

Thats the greddy manual. There must be more wires for elec gauges though. Might not help but at any rate:

Ill post if i find anything else

And this is why I had a complete set of those gauges and sold them:naughty:

They are exceptionally awsome looking ( wish HKS would come out with that style face again) but there is ZERO diagrams from HKS nor any parts still around for that particular series of gauges.

Believe me, I looked. But there has to be someone running them with the original instructions....all hope is not lost.

I've been looking all over for that gauge in PSI, how much did you get it for, and where from?

 

[MK3Brent]

lol....

Okay guys.

Red - 12volt constant
Orange - Switched ign source
Yellow - Light source (IE, lights get a 12v source from here.)
Black - ground of course.

The other wires should coincide with the sending unit...which you do have, right?

Edit... on my HKS gauges... they have 2 wires that are left untouched, as they're meant to be piggy backed with other gauges. (I assume)

Thanks Brent, I have the sensor, but its not an issue so its not pictured. The sensor is bundled with the green, gray, and brown but is seperate from those wires...Still leaves me wondering what those wires are for??

(for reference the sensor uses a white, yellow, and pink wire)

All of my HKS gauges have (2) wires left over, the only thing I can think they're for is to be piggy backed with either IGN, lights, or possibly gounds.

I left them alone, and wired the rest up permanently.
