Both my kappas have the Gm tune. Purchased years ago when GM installed with a crimp. Both had issues and I soldered and have not had another issue. I wish the connector had been available when my cars were done. So much better to be able to plug and play rather then cut wires. Order the connector from CrateEngineDepot!
