hey guys i've looked all over and havent been able to find anything on this so i figured i'd ask. for this aem boost gauge(analog) i need a switched power source that doesnt cut out at start up i cant find one at all. does anyone know which wire i can splice into or a fuse i can use, cant be the clock radio or cig lighter thos cut out. thanks any suggestions would be appreciated

 

you need a switched 12 volt source...period

why are you saying it can't cut out at start up?

 

Accessory wires show 12v at ignition but not at crank, Ignition wires show 12v on ignition and crank, you can find both at the ignition harness but an accessory wire such as radio should work just fine, that's how mine's hooked up.

 

Chaps... I'm bumping this thread after a lengthy search.

I've just installed my AEM Boost Gauage off of the clock via some other threads on here. However, when I crank... it's cutting out and re-zeroing, and as such reads zero at idle (which is bad for those of you keeping score).

1. Do I have the wires mixed up on the clock? Like did I switch the ACC and the IGN wires?

or

2. Where did you or do you suggest tapping into? I've seen someone tapping into the ECU fuse (which makes me kind of nervous) and I've seen tapping into the direct black and white ignition wire on the steering column... which also seems a little counter intuitive.

Help a brother out...

 

cigarette lighter, interior lighting, stereo power wire... these can be tapped near the fuse.

 

http://www.streettunedmotorsports.co...gtail_fuse.htm I am using these. They work great

 

Don't all of those reset when you twist the key to start though? The clock has an accessory mode... but the power disconnects when I click start. Unless I have my pink wire and my red wires mixed up?

Bottom line... which fuse, or which wire provides a CONSTANT power supply when you click the key into the starter position? If you happen to know which one of the 4 wires on the clock will do this, that's extra helpful.

 

I've a set of those... which fuses did you tap into for your gauge m8?

 

I used one of the mini size ones 10 amp. And i think it was to the power mirrors. Im not sure tho. But they really work.

 

Being that you also have an MR, would it be possible for you to go and take a quick look m8? My gauge is stuck on zero now... I'm hoping that I haven't shorted it...

Also... if anyone else has any input on this... please feel free to post up! I need to get a new lightbulb tester STAT! lol

 

I've done three of these now and have used the cig lighter for all of them, no weird issues at all, reads vacuum at idle like it should.

 

I've got to think that my vampire clips (shockingly) aren't making a good enough connection. Sometimes... the gauge will keep power during startup, and other times it won't... Maybe I'll have to get the soldering iron out this weekend... I was using the vamp clips to be sure I had it wired as necessary before going permanent btw...

I'd still like more info.

Sho... when you did yours, which wires on the cigarette lighter went to which wires on the gauge?
