New member with 2001 Jetta MAF wire issue
 

The wires for my MAF seem to have been cut and the plug replaced. I now have two different thicknesses of wires going from the harness into the plug. The wire also do not match in color combinations. Does anyone know what I should have at both ends so that I can match these up? I have it together and the car runs fine, but I still get a high input code so something is wrong.

Thanks!
