Defi boost gauge install w/ pics
guys.. this may be old but i just installed this and even though some people say that they installed it with the black with white lines for the dashboard, dont use it.. i just tried that way and it reverses backwards. so if the dash is bright the gauge is dark, and if dash dark the gauge is bright. so unless someone could correct me on what i did wrong, for future reference just use the green wire

well I guess I'll post my issue. I bought my evo used from a local dealer and the previous owner had gauges in the car. They were removed by the dealer. I tried to install my autometer boost gauge using the green wire(was used previously for gauges) and now none of the accessory button lights work. I check to see if the wire was broke and there are no signs of the wire being broken. The accessory lights work if the dimmer is unplugged, but they go out as soon as you plug it in. Also the cluster doesn't work when the headlights are on unless the dimmer is plugged in. I guess I'll wait to see if any of you can come up with any ideas on how to fix it without having to buy a whole new wiring harness.
Im trying to do the install right now as i am typing and i need help for 2 things...where do i tap into a power wire? and where do i tap in for ignition? really need a response...thanx. BTW i have a defi bf boost gauge

well I found my problem and feel stupid for it too. Come to find out the dimmer switch runs off of the parking lights circuit. I had blown one of the 2 parking light fuses, replaced it and everything works fine now.

Cut and put your "T" into this line here. I removed the plastic coil wrap.
The line is cut in half and the "T" connected. Here's the finished product. I went ahead and ziptied the connections and also wrapped conduit/wire loom around the vacuum line to give it a presentable look. The line was ziptied to the strut bar to tidy things up a bit.

Has anybody found the problem with the dimmer switch tap yet? I got that "reverse" issue too. I just wanna see before I call it a day and tap it into the green and white wire.
Nice write up with good details... FYI one thing that simplifies the whole install is using the black wire right next to the green with white stripe as the ground. It's a ground wire for the illumination control and is much easier to tap than attaching a chassis ground.
