    1.8t maf wiring harness diagram or info?

    I am not running my stock air box as I have a turbo in the way. So I have a cone filter with the maf right behind it. My maf harness has gone through the ringer and one of the leads started pulling out. So I decided to re-do it with heavier wire that would be more heat resistant. ... I can't remember what colors went where.
    1.8t aeb 99- 4 wires. can someone please tell me what order they go in.

    Four wires, huh? Odd; I thought it was a simple ionization/collection setup, where the amount of electricity that makes it from one electrode to the other is inversely-proportional to the amount of air passing through the housing.

    Is the MAF also heated, by any chance?

    bumpin a old thread for information

    Which end has pin #1? Its for a B5 AEB engine harness and the connector goes to the MAF. Its the only one I didn't take a picture of when I disassembled everything. I do know I have the wiring order correct according to the Bentley manual, but I don't know which end of the connector #1 is at. Any help?
