Just got done doing the full delete on my truck and went with Motor Ops Auto Cal with 5 position switch and since then my driver's side turn signal hyper flashes. No bulbs are out. Could this be something with the pin placement for the lsp switch or something else.
Never heard of this. Dumb question...but Is the bulb out?
Have you checked, and double checked, and triple checked you put it in the right pins? I know each tuner is different and the "first" youtube video found may not be the right one.
Im like 99% sure the turn signals are controlled by the BCM and not the ECU, as the BCM is inside the cab, im also fairly sure you didnt mix them up, so i think its unlikely that the two are related. how did you run the wires through the fire wall? did you go through the hood release or did you poke a hole through the main harness boot? if you went through the main harness boot maybe you damaged a wire along the way?
