I searched on how to install this map sensor and read that you must leave the stock sensor alone just hook this one to a vaccum line and splice the wires on the stock sensor. Just wanted to double check if this is true and if anyone knows which wire goes to which. thanks.

 

Yes I am also very confused on this one if someone who has a 3bar on there car could chim in!

Cut off the stock plug

solder in the new clip

electrical tape

done

I forget which wires go where though...it's not hard to figure out just by looking at the colors. Black is ground, yellow or even red (usually yellow) is 12v+ and the weirdo color will be signal.

 

I have to hook up the new sensor to a vaccum line as well right?

 

Yep. You can take it from where the EVAP connects since the hose is big enough and you can find a Tee fitting easier.

If you make a block off plate, you can take out the original map sensor (leave the o-ring). Or you can just leave the map sensor there like I did if you're lazy.

I put mine right under the Fuel rail on a bracket that was made for me by my Tech Joshua at Fournier Automotive in Orlando - If you need a close up of the wiring let me know and I can snap a pic tomorrow for you!

 

Man thats a lot of stuf in that picture. If you could just take a pic of which wire goes to red, white, black, that would be GREAT!!!

 

That's a pic of the GM 3 bar...not the AEM 3.5

 

Don't forget to change the sensor in the AEM.

Setup>Sensors>Manifold Pressure Sensor>MAP Sensor Wizard; then choose your sensor from the table.

 

About that, I know that the graph will change and display up to 30lbs. Do I copy my current graph over that and set it all up to lets say 14psi or keep it up to 30 but just copy my graph into it.
