I installed 4 Prerunner lights to the grille of my JT. I connected the lights to the 15 amp Aux switch and grounded to body via one of the grounding bolts. Now the check engine light is on but the Prerunner lights work and the truck seems to be fine. I tried grounding to a different location but still having the same issue. Anyone have thoughts on what the issue could be?
