Hi guys, so my greddy boost gauge came in. I'm in need of help. So it comes with a piece that connects to the gauge that has 4 wires on the other end, black, white, orange, and red. I was able to isolate that the black and red were power and connected it to my battery to test the gauge. I have no clue what the orange and white ones are. The manual is in japanese so it's no help. I was able to bring the wire connecting to the vacuum nipple on the uim into the car. Where should i wire the 4 wires to have a clean install? My fd doesn't have a sunroof, is there a way i can use the sunroof fuse to wire it?

I also got belts for my car. Do i just find the tensioner to loosen it then just install it? Does an o2 sensor need soldering to intall?
Thanks for helping me, I hope i can finish this by tomorrow.

 

So I put the orange and red wire together and stuck it in the sunroof fuse.I got power and the Guatemala is reading. Will this work or hurt the gauge since orange is ignition? Will the white wire work on the ashtray?

 

Okay so I got the gauge working. It stays under 0 when I'm driving wheni boost it will go to 10 Psi it goes a bit higher sometimes. Does this seem right? Do you think this is because I put the orange and red wire together?

 

GReddy's website has a technical section with English instructions for all their products.

I forget which it is, but either the orange or white one is for use with a dimmer switch, the online manual will make it all clear for ya.

 

The wiring guide is right there on their webpage in the Tech Support section -

Oh crap I connected the red and orange into the same source. That was the part I was confused about. What does it mean 12v constant and 12v ignition? Right now I have the White one spliced in with the ash tray light. The black ground i have wrapped around a screw. I have the red and orange in the sunroof fuse. It was working last night. But Greddy said not to put red and orange together. Where should i put the orange one? Thanks Xevenskyline and daleclark for showing me the links.
