Power antenna switch

[BEMSTER 3]

Hello everyone. My Reatta is in pretty poor shape, but one of the few things that works great is the power antenna. I would like to install a switch on the wire that powers it so that it will not go up every time I turn on my headunit to listen to CDs. However, I cannot tell which wire powers the antenna. Could somebody tell me which one I should install the switch on?

Here is the schematic for the power antenna.........

I think the simplist solution is........ on the wires coming from the front of the car,  put a switch in the black wire (ground)  If you remove ground, the antenna will not go up or down.

I would need to do a little more research but you might be able to do that at the radio.....just not sure where that ground wire goes....

 

Update 6/10/18......the black wire goes to S315 which grounds in the front of the trunk...different spots on coupes and convertibles, so if you want the switch up front, you will need to run a wire.

i did this.i think that i might have looked to see what color was at the antenna and then cut it at the radio module. i used a piece of speaker wire to run to a switch.

I'll go out to mine this evening and look.  I know I spliced into the power wire for the antenna to use that 12V as a remote wire for my amp.  I believe it was the orange but I will edit this response when I go confirm.  If you don't already have one you should invest in a test light, or better yet a multimeter then you could test which wire went to 12V when the radio was powered on.  I know that in the long run you will definitely need one with these particular vehicles.  Takes a lot of guesswork out of troubleshooting the various electrical systems we have.

In the diagram above.......the ORANGE wire is hot all the time......the PINK wire is hot when the radio is ON

Yep Barney is correct. I tagged into the pink wire for my remote wire. So you could make and break that one or the ground which was previously mentioned.

I attached a toggle switch to the pink wire, and it works perfectly. Thanks guys.
