Default Advice removing c3 79 power antenna wiring

Hi, any thoughts on how to remove the wires to the power antenna?
i have it loose and antenna off but appears the wires are direct no clip to remove.

I removed the carpet to the door and there are no connections to the antenna... is it normal to cut (assume cut inside) and splice back in?

thank you

No connection

follow the wire from the grommet inside the car forward .if nobody changed the antenna motor in the past there should be a plug or a splice.

a splice would indicate a old repair

Seems i may be an early 79?


Remove the antenna from the car. Some guys feel it’s easier to remove the left side muffler. You can also remove the 4 bolts at the catalytic convertor and rear hanger and remove the entire Y pipe/muffler assembly.
I’ve found it easy to remove the antenna with the muffler in place, just have the car at a comfortable working height on a lift where you can reach straight in without bending and twisting your arm.
Disconnect the battery.
You’ll need to cut the green/gray/white wires as there is no connector between the factory antenna and relay under the center

Leave plenty of wire on the antenna. I like to remove the rubber grommet at the body and carefully slice it lengthwise to remove it from the cable/wires. That way I can resplice the cut wires and put the splices beyond the grommet inside the car body to hide them.

Did your car have a factory cb ? My 79 didn't.

If it is an early 79 style antenna, aluminum housing with a plastic fender grommet, there is NO plug behind the speaker.
You gotta cut and resplice the wires. Unless you want to remove them all the way to the relay(gotta remove some carpet).
Plug was added when the newer style antenna was introduced late 79.

No rivets on your early antenna.
LATE79-82 has the rivets.

No, that's the right side. Everything accessible from there. Carefully remove everything watching how it's installed and you will get to the broken nylon cable at the bottom.

Cable available from antenna source.com(formerly antennamastsRus)
I think they charge more for the NEW '78' style than the late79-82 style but the later one will work. That's what I always used.

Yeah, sometimes that section of the motor can be pretty corroded from the steel mast tube/aluminum connection.
