I,ve recently purchased a 80-87 short bed k10 with a new crate lt1 engine and a rebuilt t350 tranny and both axles werew rebuilt with possi . Also new sheet metal 8yrs ago and the past 3yrs it was parked in a barn to rot.It runs ok but starting to have problems now ,first the rear lights went out and found bad wiring from last owner but it is all working good now and properly wired.
Now my horn does not work found 2 horns on the rad support and tested them ok ,the fuse is good ,is there a relay for the horn ?
