hey fellas ...I ended with the “a&b” harness when I purchased my g4+ ecu, it will be getting wired to a drag only n/a vehicle... some say use it some say use the proper tin Motorsport wire? What’s your thoughts ?

For a dedicated motorsport application, my advice would be to build your own harness from M22759, or 'milspec' wire. Up the top of the forum there is a post that has the part numbers for the AMP Superseal 1.0 pins you'll need. You can re-use the connectors from the link harness after de-pinning them.

Also, for a dedicated motorsport harness, I'd suggest these: https://racespeconline.com/products/racegrade-amp-backshells?variant=20832775169
