HKS 60mm old gauge wiring, warning problem

[Snara]

Hi,

If some one have/had gauge like this can tell me how to connect it properly?

I have 2 connectors, 1 is for gauge and I connect all wires, 1 is for sensor and from sensor connector i have 3 free wire:  gray, green, and brown.

The problem is my Warning don't work, I set it from behind at 2.0 bar but when i test and pump over 2 bar the red LED doesn't blink  And when i connect brown wire to black wire from gauge it blink all time.

So my question is how to connect it properly ?

Got photo of the receiver/sender unit?

I had the same problem with my old Tomei gauge but i worked it out.

Basically .....

The gauge itself has Black/Earth, Red/Power, Orange/Accessory, Yellow/Gauge light

Then 3 extra wires from gauge to Sender/Receiver unit, these are just Earth, Constant and Accessory.

My only problem was the Accessory and Gauge light wire's color so faded i couldn't tell which is which so i wired them both together.

As for warning lights .... i'm yet to know how to set them. The Tomei has 2 buttons at the back and one at the front of the gauge. Mine flash RED at 5psi and then at 15psi. Obvious there are 2 pre-warning and a recall.

Damn  I have only gauge and sensor.

So without unit i can't use warning? shit

No ....

Maybe HKS built it differently so gauge and sensor is all you needed. You mentioned you tested it at 20psi so you must have connected the boost vacuum line and all is working right?

I'm sure you can use warning, just have to try to figure it out. 

[Snara]

Yea, i have connected boost vacuum line and it show me boost and underpressure but warning don't work. It should turn red led when i exceed the target pressure which is set to 20 psi but red led is turned on all time  

So no one on that forum never have that HKS boost gauge and can't tell me some hint?

Hint - try Google - there are loads of entries I don't have the time or inclination to read but you can sift through them.

Sure, first what i do i search on google, it's many threads but i don't find any HKS wiring diagram or problem with warning 

So i need someone who know that old HKS gauges  

My friend make video, looks like that gauge need some unit for working warning :

Late reply but if the three spare wires that go to the unit need constant, acc and earth couldn't you just wire them up that way and still have the other features work?
