boost/afr gauge install
i just bought a use set of autometer gauges. the boost is the cobalt (6103) and the afr is the ultra lite. they didn't come with everything needed (like instructions) so i'm kinda confused.
i know i'm going to need an o2 sensor, so that should be too tricky.. but what i'm confused about is the boost gauge. where do i run a vacuum line to? what kind of tubing do i need? etc etc etc. any info will be really appreciated my cars a 91 tII if that helps thanks |
I imagine the 6104 or 6105 are almost identical in installation, so this link should help...
Cobalt Boost gauge 6104 Mario III |
i looked at that earlier and it didn't help. but now that i actually studied it, it makes perfect sense.
thanks! |
A narrowband AFR gauge (the $50 kind) will just tap into the single wire on the stock O2 sensor.
A wideband gauge (~$250) will need a wideband O2 sensor. |

So buy one. They're about $20, and will save you far more than that in gas money. There's no reason not to have one.

... this might be kinda useless, but a good place to mount one is right where the cigarette lighter is..
