Does anyone have any good ca18det wiring resources?

I have a ca18det wiring harness that had the wrong MAF wired in (4 wire KADE?). I have the right MAF now, but I need to know which wire goes where. I don’t trust that they got it right in the first place 😉

I’ve got a spare CA18DET MAF if you want the ‘actual’ one…

On the SR and CA MAF the pinout goes:

Pin A - nothing / not needed  
Pin B - +12v power  
Pin C - ground  
Pin D - air flow signal out
