Recently, I added a late model power antenna to my 66 GP. I wanted to keep my stock switch on the dash, and this antenna was wired different than a 66 antenna is. Using a couple of relays, it's easy to do. I am not an electrician by any means so it took me a bit to figure it out.
A little while back, on a different Pontiac forum (out of the US) someone asked if it was possible to do what I had done. I replied that it was easy and I could help him. However, when he told me how the antenna was wired that he had purchased, it was different again from an original antenna as well as different than the one I had done. Again, it was just a matter of some figuring out on how to wire it with 2 relays and yesterday I was able to tell him how to get it working.
For you guys who do electrical just 1-2-3, this will be basic and boring. I enjoy this stuff, but I'm slow at figuring it out. I'm posting this for the guys who are intimidated by something that requires wiring changes to make it work.
___________________________
Style 1 antenna is easy. The body has a ground wire, a wire for up and a wire for down. This is how it was in 66 and I know a lot of other years of Pontiacs as well. They are simple. Ground the antenna, feed the white wire from the stock switch to one antenna wire, black from the switch to the other wire and it's done, it works.
___________________________
Style 2 antenna is a bit tougher. It has only 2 wires, and no ground wire. If you hook up the 2 terminals on a battery, it will go one direction. Reverse the wires and it will go the other direction. To use the stock switch on this one, you must use 2 common auto parts store 5 pin relays like this.
Wire the 2 relays up like this-
If you are looking at the relays, that equates to-
LEFT RELAY
Pin #87 12 volts (fused)
Pin #87a ground
Pin #85 ground
Pin #30 white wire from antenna
Pin #86 white wire from switch
RIGHT RELAY
Pin #87 12 volts (fused)
Pin #87a ground
Pin #85 ground
Pin #30 black wire from antenna
Pin #86 black wire from switch

Style 3 antenna
This one was tough for me to figure out, easy for you electrical gurus I'm sure!
It has a black ground wire, and in his case, a red wire and a blue wire. First, he grounded the black wire. Then he powered the red wire, the antenna went down. When he powered the red and blue wire at the same time, the antenna went up.
That requires doing the relays this way-
If you are looking at the relays, this equates to-
LEFT RELAY
Pin #87 to antenna "down" wire"
Pin #87a blank
Pin #85 ground
Pin #30 12 volts (fused)
Pin #86 "down" wire from switch
RIGHT RELAY
Pin #87 to antenna "up" wire AND a jumper wire to pin #87 on left relay
Pin #87a blank
Pin #85 ground
Pin #30 12 volts (fused)
Pin #86 "up" wire from switch
Hopefully someone can use this to keep their original interior still looking original by retaining the switch.
I did this because a decent affordable original 66 power antenna is a tough thing to find.
Please let me know if I have made any errors on this. I proof read it and I think I have it right, but I picked up an ugly cold once again and my head has not been the clearest.

I was just thinking how cool a remote control power seat would be, or a wireless remote control fold down license plate for those red light cameras, or .....................
Sky's the limit!
