3 bar map sensor wiring help?
This is intake manifold 3 bar map sensor wiring
So I found my problem probably for the issues I have been having guess I did not notice b4. The fourth wire was not fully connected so I pulled apart completely . I pulled back tape to splice again and noticed the 3rd wire is not connected to anything. Is this normal? Thanks

The manifold mounted MAP only uses 3 of the wires, the one in the charge pipe uses all 4. I snapped a picture of the plug and play harness for you, I should have uploaded it to your other thread but after seeing this that adapter no longer applies, you'll have to re splice and heat shrink this as the factory connector the PnP harness goes to is no longer there.

It's possible it could be your code, but you gotta fix it first and clear it to see. As to your cutting the plug and play, just cut the 3 cavity plug off leaving the 4 cavity plug and wires, and splice them together. You could use butt splices like the previous install was, but the better way is to solder them. Either way, after you connect them use heatshrink over the connections, then electrical tape over that. You could also get more of the black corrugated elctrical wire covering to put on after the heat shrink and tape over that, looks more like a factory harness.
Just make sure when you start do one wire at a time, makes it easier and if you forget you don't need to hunt down a wiring diagram.

Theres a link to purchase that plug from a supplier other than CED for a fraction of their price. I can confirm it does fit correctly and work.
