3 bar map with digital dash

Im having trouble finding these connectors for the 3 bar map sensor. Are all of the connections the same for the 85 GN models as the 87 Digital Dash?

digital dash 3 bar map

ok i know where this is at.where are the wires that i jump these to? im confused.

im getting 2.25 v at my map sensor (center) grn wire. key on engine off. and my analog dash boost gauge (stock) has always been off, it says im at 6lbs of boost at idle and when i hit gas it max's out. i have an auto meter boost gauge on A-pillar for accurate readings. is my map sensor bad?

how do i know the diff between 2bar or 3bar? plz

im really bad at explaining myself in detail. :redface: what i meant was how do i know then if i have a bad 3 bar or a good 2 bar? is there any numbers on the exterior of the sensor that will tell me?

the answer was a simple search away , if you'd searched 'map sensor id', its been posted here quite a few time over the years and my old posts here was the first hit using google

MAP sensor identification information GM 1 bar 2 bar 3 bar

if your stamped #s say its a 2 bar than you have your answer , if it says its a 3 bar butdoesnt give you the voltages of a functional 3bar as razor described (approx 1.6v with key on 0psi , 0v at -15psi vac ,approx 5v at ~30psi boost ) that the kit is looking for you will need to get another sensor
0psi/1.6v is easy to test motor off key on sensor plugged in to 5v with a ground connected
you can use a vac pump to test lower value and compressed air to test the upper

oh and because of these defective boost /tach modules i dont reccommend running the sensor off them as thats where the 5v source for the map sensor comes from .
if you have 5v fine but i like to run the map sensor as if you had a digital dash with the map power pulled off the tps 5v circuit of the ecm as this thread was started for from the beginning

Idea

This what i'm using makes it so easy to use.
