LMM Pinout: Switched Positive & Location

Hello,

ich suche dringend die Pinbelegung für den Stecker am Luftmassenmesser, also genauer gesagt das Kabel wo der Messwert des LMM rausgeht. Laut eines Postings hier müsste das am Stecker der Pin 5 sein (Kabelfarbe?). IIs that correct?
Besides that, I'm currently trying to figure out the best place to tap into a switched positive connection for power supply.
I would like to install a power box from Zemotex (D-Chip).
'Does anyone have a tip?' or 'Any suggestions?'

Thank you, Jürgen.

Hello Jürgen,
What kind of car is it?

Best regards, Rudi.

I forgot, sorry.

Volkswagen Golf IV TDI, 66 kW, ALH engine, manufactured in 1998.

Hi,
During the 1997/98 period, the change was made from a 6-pin to a 5-pin MAF sensor connector. If it's the 6-pin connector, you should use pin 6 (purple/brown); with the 5-pin connector, use pin 5 (brown/blue).
Before connecting anything, please measure the voltage at the corresponding pin. It should be around 1.5V when idle and increase as the speed increases.
As a switched supply, for example, the positive connection for the shut-off valve can be accessed at pin 8 on the ESP connector.

Best regards, Rudi.

Thank you.
You saved my weekend .

Best regards, Jürgen.
