hi all
bought an r-spec boost gauge and having a little bit of difficulty figuring out the wiring sheet they have given me with it, I will try and make as much sense as I can when explaining this
wiring instructions for gauge:
red - 12v accessory power (ignition im guessing?)
black - ground (I know where this goes lol)
white - engine accessory power (does this go to the boost sender? if not what does it connect to?)
orange - head light switch (iam being told not to use, by the instructions)
green - boost sensor, connect to white wire from sender (also know)
wiring instructions for sender:
black - ground (this just earths on to the engine or chassis somewhere? i don't think this returns to the gauge?)
red - accessory power (does this need another 12v ignition feed? or does this connect to the feed from the gauge white wire?)
white - green wire from gauge (i know)
last but not least lighting diagram says for blue (day) and blue (night)
white - connect to acc. power
amber - do not connect
it also allows me to light it red but i do not want to do that
any help is much appreciated as the instructions suck a** and i don't quite understand them, nor do i want to bu88er my new gauge lol

Re: [Mk2] [Turbo] r-spec digital boost gauge
Don't take this as gospel, but I would say:
red - 12v accessory power [12v Permanent Live]
black - ground [Ground]
white - engine accessory power [12v Switched Live - a wire that goes live when ignition key is turned]
orange - head light switch [Dimmer line - connect to any wire that goes live when the lights are on]
green - [To sender]
wiring instructions for sender:
black - ground [Ground]
red - accessory power [12v Switched Live (from the wording I would say permanent live, but don't know why you'd want a permanent live to the sender??]
white - green wire from gauge (i know)
Not certain on this bit, but I guess it means to light up blue, connect the white to switched live and leave the amber disconnected.

..the only thing I can promise for sure is slow progress.

just have this niggling thought that if I rip out the wiring, then the car will never get out of the garage again.

Gauge
Your spot on with your guess mate did a lot of research last night and that is exactly what I came up with
Just off the phone to Peter and he also says that the sender should be ignition feed only because live constant will contribute to battery drain

Re: [Mk2] [Turbo] r-spec digital boost gauge
On,y two thought really:
1. Swap the red and the white
2. Your switched live isn't actually a switched live
Do you have a multimeter?

Gauges
I did think I may have the red and white around the wrong way
This gauge is for my subaru and they sit where the clock sits
Yeh got a multi meter and I defo have:
Constant live
Ignition
Earth
Illumination
Or else my clock wouldn't have worked
I'm pretty sure it's because those 2 are around the wrong way but I will try it 2moz bit late the night
I prefer asking questions here because I get more direct answers than the scooby forms
Also Iv found on the net that I need a constant live to the gauge to keep its memory but I haven't started the car then switched it off only ignition
I don't suppose this would have anything to do with it?
