I need to know what each wire is for on the Mass Air plug. I'm working on a experimental project.

I also need to know what each wire is for from the plug of the ECU. I am building my own harness instead of buying one.

The car is still drivable so I would like to build the harness and just swap it out.

Also I would like to know if anyone has a detailed vacuum line diagram.

I tried to go to the manual download link, but it is shut down.

Thanks for any help.
