ok i when i purchased my truck my check engine light was not on so i just figured nothing was wrong but over time i noticed when i was starting the truck all the lights were on but the check engine light so i checked if i was trowing any codes and i was. now i come to realize that the dealer that i bought the truck from disconnected the check engine light..... so does anyone know how to reconnect because i dont know s*** about electrical systems?

 

There are a few ways to go about this.

It depends on how it was done.

Did they just remove the bulb?
Did they tape it?
Perhaps the bulb really is just burnt?
Did they cut a wire?

Those all play into how you start to resolve this problem. How long have you owned the truck?

 

almost a year now
