Boost/Vac gauge

[AgntorangeDSM]

well heres the deal, a some kid was hanging around a group of us one night and he gave me a Cobalt Boost/vac gauge, sweet huh??!! well only one problem, i only have the gauge and its electric so i have no wire harness and the only thing i get from autometer.com is a wiring diagram as if i had everything. i'm not real sure what i'm missing so if any body know's what i need? and where to get it please let me know? thanks!!!?? "its a brand new, guage only"

you shouldnt need anything more than that. The new guages are normally just the guage itself with a few wires running out of the back of them. Thats all you will need is that diagram and hook up your wires (extend the wires on the guages) then let her rip. Hope you can figure it out. I might be wrong, they could come with some sort of harness but i have never seen a guage that did, all the ones i ordered from autometer were just wires, no plugs or harness.

I really hope you are talking about a mechanical gauge and refering to the wires for illuminating it. The Cobalt series are eletrical and not mechanical.


You will need a way for the gauge to turn the boost/vacuum reading to an electrical signal. I have heard and that Autometer uses a GM MAP sensor but I don't know if they use the 2 or 3 bar sensor. If you could find that out then you would just have to order one, like 60.00, and you should be good to go.

This page has pics and links so you can buy. I would try and get it GM Part Direct.

my autometer only came with the lighting wires out the back and a spot to read the boost/vac via a vaccum line

Your gauge was mechanical his is electrical.

Your gauge was mechanical his is electrical.

gotcha!

its probably stolen

its probably stolen

thats what i was thinking when i first read it... but i didnt wanna bash him or anything...

they make mechanical Cobalt gauges as well...

can we see a pic?

I see that. I stand corrected.

Then we would need to know if it is a mechanical or electrical gauge.

ok its electric but it has about 10 pins on the back but NO wires for it so if i knew what the pins were i could just solder in my own wires and be on my merry way but that's what i'm looking for is the pin out's for where each individual pin goes. (not mech. its elec.) and yes autometer uses a map sensor here is the diagram they give me but thats only if i were to have bought it from a store!! http://www.autometer.com/download_instruction/569.pdf thats all i get and the wires from the gauge out are not there its a guage only i really wish i had a stupid digi cam!!!

 

[AgntorangeDSM]

i called Auto meter and they said they would send me the rest of the kit for roughly 25 bucks!!! so that's what i might do, thanks every one for your help

Whats the difference between mechanical and electrical gauges?

Whats the difference between mechanical and electrical gauges?

Mechanical gauges actually measure with the media they are monitoring. So a mechanical oil pressure gauge actually has oil come into it from the motor to measure the pressure. An electrical gauge has a sending unit that takes the pressure or temp, what evere the gauge monitors, and turns it into an electrical signal. That signal is then turned into pressure or temp, again whatever you are monitoring, at the gauge for your read out.

That may not have made the most sense, sorry.

Just incase boostedinaz's post doesn't make sense , here is my version.

Mechanical gauges are mostly for pressure. If you want an oil pressure gauge in the inside of the cabin, it is safer to run an electrical gauge that way you don't need to run a line with hot oil all the way in your cabin. If the line has a hole in it or breaks, you'll be burnt.

Electrical gauges are mostly for temperature, however they are some electrical pressure gauges. EGT, water temp, volt etc are all electrical gauges. Mechanical pressure gauges takes pressure and display it on the mechanical gauge. Electrical pressure gauges take pressure, convert it to an electrical signal and then send the signal to an electric gauge.

Another factor is cost. A mechanical boost gauge is about $40-$50, a electrical boost gauge is about $150-$200. In the end they both display the same thing, BOOST, so why spend the extra money, unless you have it, ofcourse.
