Boost Gauge Help

[GTS R33]

Hey Guys,

So finally after looking at my busted gauge too long I have decided to buy a new one. Boost/vacuum lines all hooked up went for a test drive all fine, now to hook up the electrical and not sure what to connect where. I already have the cable through and ready to connect to stuff.

Old gauge had the orange not connected to anything, and then the other 2 hooked up to a red and a black wire under the dash. Now I'm not sure what one is what and if previous setup was even connected correctly as it was intermittent with the led working. I would just press the led change button and the light would come sometimes on, so it wasn't connected to the night lights I'm presuming.

The new boost gauge has:

White to 12v dash lighting

Black to ground

Orange to battery

Where do i find these under my dash so I can connect it up. i don't have and electrical test equipment or wire cutting devices just pliers, scissors, knife, electrical tape and zip ties. Just putting the boost lines in made me feel like Macgyver.

cheers

I live northside and if someone wants to do it I could arrange KFC or some drinks of choice as I believe these are the going rates for SAU help.

Where abouts do you live mate? Happy to meet up and pull my dash apart and try and mimic the wiring.

Chermy, pulling your dash out sound like a lot of work, but I don't think you can mimic it, there seems to be speaker cable wiring everything to everything and I don't think it goes to the speakers, Chris Rogers said it looked real messy under there when he did my ignition barrel. I might take it to him if I can get time and he isn't busy. Should be a 10 min job for him as the wires are ready to go. He prob take 1 look and know what to join where. Might send him a PM.

Give me a call at some point. It is a 10 min job.

If you don't really care about how neat it's going to be, the easiest place to connect it up would be the head unit wiring loom as it will have all 3 of those (depending on headunit, the white to 12v dash lighting would be for a dimmer when you put your lights on which your head unit may or may not have). You can just pick up a fairly decent multimeter for $20-$30 and will do the job. Your head unit will have 12v battery and ground 100% but it depends who wired it and if your head unit actually has the dimmer or not.

^smartest/easiest option for sure. If in doubt see the electric guru.
