Tuner Accessories — SOTF Switches, Harness Plugs & EGT Sensors
Your tuner is only as good as the hardware supporting it. TruckTok stocks the accessories that make tuning reliable: shift-on-the-fly (SOTF) switches and knobs for switching power levels without touching a screen, generation-specific tuner harness plugs for every locked ECM from 6.7L Powerstroke to L5P Duramax, and EGT sensor probes for accurate monitoring. Also — block-off plugs for EGR throttle valves, DPF pressure sensors, and DEF injectors when the factory hardware is removed. Not a tuner. Just everything your tuner needs to work right.
