How to install Trailer wiring s10 blazer?

Answer 1

All S10 Blazers are not "simple plug in type setups.  Some require splicing in to the wiring harness located under the rear of the vehicle.  Depends on what year yours is.  Mine is a 1998 four-door and the manual tells you the wiring harness stub is at the rear of the vehicle on the drivers side. On a two-door, it is on the passenger side.
