Hi knowers, i own a 77 Blazer K5 and i am seaching for the electrical cable for the antenna Motor. Where does it enter the cab an which color is the cable? Thx

 

The antenna should be integrated into the windshield (center bottom should be a snap like connector) and would not have passed through the firewall into the engine compartment.

If it has been converted to a fender mount, you'll need to follow the current cable to see where they passed it through.

If it hasn't been converted and you want to move to a fender mount, you'll likely need to drill your own hole and procure a grommet to protect the wiring. Anywhere under the HVAC box should work, but make sure you check for obstructions on both the inside & outside before drilling.

 

Thanks for the fast reply
