Hell All,
On my 2016 SL LE, I just used the one from GM. The harness fit perfect. I disconnected the battery, and the plugs on the ECU for 12 Hrs and the light was still on. I drove it for months with the light on expecting it to shut off, but it never did. I took it to the cloest dealer (Mom's) in Foxboro, MA and they shut it off for free and it hasn't come back on yet!
