DSP5 2016 Silverado 2500 Duramax LML

I have a 2016 Silverado 2500 Duramax LML and I already deleted it with the autocal EFI Live and I bought the DSP5 switch and it came with a quick connect instead of going to the ecm. But I can’t figure out where to plug the DSP5 plug into. Same day tuning only told me it’s somewhere by the turbo and the firewall. Please help!!

I didnt think you can switch tunes using a 5dsp switch, only loading one tune at a time.
Youll need to contact your tuner.
