Has anyone wired the 2004 Blazers for a trailer... It doesn't appear to have the towing package...

 

Easy to wire up a four flat plug as the wire "should" be dead ended near the bumper but a bit more entailed for a seven round. For the seven round you will need to tap into the brake switch and to 12 volt power.

 

thank you

 

Has anyone installed fog/driving lights on 01 blazer? I am having difficulty figuring out how to get wiring through firewall. I found a small plug just above the gas pedal with no obvious receptacle. I has a green and white jumper installed. Was hoping this went to the engine bay somewhere. Just need control wiring no power.
