Hks Chrono Gauge Install

[Omurru]

I have a couple of HKS Chrono gauges I am currently putting in my car, I bought them second hand and they didn’t come with any instructions. I’ve got everything figured out except for where the 4 wires on the power harness go? Anybody else got these installed in their car or know where the wires go?

The wires are coloured as follows:

- Red – (I presume goes to a 12V source but does it need a constant 12V source or an ignition one?)

- Black – (Earth)

- Orange – (I think goes to the parking lamp signal)

- White – (No Idea)

Correct me if I am wrong on any of these but any help anyone can give would be much appreciated.

What are the gauges for ?

Ones boost ones water temp. It's not the actual wiring of the gauges, that easy. Cos they are electrical gauges the controller thing for them has a power harness which I am stuck on wiring up.

Thought I might just put this up for future refrence for people, have finally got my gauges installed and working. A few notes for anybody else who might be having problems with electrical gauges.

What the wires go to:

- Red – Goes to a constant 12V source, I wired mine into a random line that happened to have a 10A fuse on it I found under the dash, think it might be part of the alarm

- Black – Goes to a Earth

- Orange – Goes to a 12V ignition source, I used the cigarette lighter (cos it's easy) this turns the gauges on and off

- White – Goes to a 12V light source, I used the light around the cigarette lighter, this is so when you turn your lights on the gauge lights come on also.

***Note*** Can't remember which way round the White and Orange go, but just try it one way, turn the accessories on, if the gauges come on and the light behind them turns on/off with your parkers you got it the right way round, if not try it the other way This should be the same for all types of electronic gauges regardless of the 2 other colours, ie red and black will be +ve and -ve the other two will be on/off and backlight just have to work out which way the other 2 go .

I had a problem with my gauge that the boost gauge wasn't reading anything, was just getting a flashing red light, this means that it isnt getting a reading from the sensor, after doing some checks I found that the wires were broken somewhere in the cable between the sensor and the control unit, so I had to rewire it and all works fine now.

On a side note I didn't like the white light of the chrono gauges so I got some thick blue celophane and cut it to fit behind the face of the gauge, so it's held in place between the black case of the gauge and the faceplate with the numbers on it, so now it matches the rest of my dash lights
