hello, i need some help installing a vacuum gauge in my 83 z28.

My problem is, i cant find the 12v dash lights, and the 12v ignition switch under the dash, is it a fuse or what?

You can get the 12 volt dash light wire at the back of the headlight switch. I think its a brown wire. The 12 volt ignition wire should be a larger pink wire coming out of the ignition switch on top of the steering column under the dash.

 

I hooked it up to a couple fuses yesterday, i have it wired so when you pull the light switch all my tachs light up. cons?

 

That's the way it's supposed to work.

 

perfect, do you have a visual of my fuse box and what fuse does what. Link? mine is faded, its for a 83 z28.

 

what is the reg vacuum for idle?

 

Depends on your cam. Probably about 18 inHg or so stock.

 

i have a air fuel mixture gauge also, it comes with a sensor . where does the sensor mount to? intake manifold?

 

An O2 sensor bung in the exhaust
