1966 Radio Install

[pntrbil]

I can help you with the orange wire marked "ariel." That's for a power antennae. That way the antennae is only up when the radio is on.

You don't specifically need to use the brake light circuit for the hot either. Just poke around the fuse box until you find something that's still hot when the key's off. That'll work.

The circle connector ... just guessing, but it's good bet the red is power. Gray and green are left and right, or vice versa! One black must be ground and I can only guess the other black may be for a separate speaker return line.

I don't even know what the RCA thing is and I've never used an amp so I'm no help there!

The other is what I remember from installing stereo's on the weekends years ago. Hope it helps.
