MAF Wiring Questions

[jajou318]

I know(now thanks to Gunni's post) that I need to get to these wires. Is it just tapping them from the ecu? And how do i know which wire it is? Is it as easy as counting the number 41 wire and the #77 wire?

41 AFM Input (5v) GY/YL
77 Air temp input GY/VI


Also, I have no clue as to where to look for the TPS signal  ::
edit: dude8383 showed me where it's at... Guess i have a diff q now.. is there only one wire behind that grommet and covering?

As for the oxygen sensor for wiring the guage I could just tap that directly from the oxygen sensor so I think I'm ok on that.
edit: i believe there are two wires, anyone know which one to tap?

I disconnect the battery and the ECU and then I use a continuity tester to figure out which wire goes where.

I had to run an 12v wire from the ECU out to my MAF. Otherwise I was able to use all of the stock wiring.

Ok, I've found the wire for the a/f ratio guage.
70 O2 Input BK

I honestly think that may be it.
