Just having the electronics available would for me be an assurance and i could buy the VW Maf later on if needed.
Then obviously it would be interesting to see if a new MAF would improve performance , but not sure it uses any info from the MAF at full trottle?
For the connector issue, if we have a connector matching the ( VW maf ) you only need 10cm cable from that to get under the acoustic engine cover , so any crossovers should not show anyway.
