In-Line Mute Switch - TA3 configuration - need advice

I'm sure many of you have been in the situation where you weren't consulted before a purchase, but asked for advice afterwards.  See if you guys can see what's up here.

Our athletic department purchased this UHF wireless system with the intention of using for mic-ing the referees at football games.

It's not a bad unit for the price.  The bodypacks have a mute switch obviously, but the refs want something a little easier to mute/unmute when announcing penalties.  

This is where I was consulted.

The GTD bodypacks use TA3 plugs, and for the life of me - I could not find an in-line mute switch that used the TA3 interface.  (at least not one that wasn't exorbitantly priced)

So, I decided just to find the mute switch I wanted and see if I could make it work with our bodypack and headset mic.  I purchased the Shure WA360 which uses a TA4 interface.

I found the correct adapters to get this TA4 mute switch plugged into our TA3 equipment, and not surprisingly, it does not work.

I suspect the problem is with pinout.  I have discovered tonight through a little googling that pins 2 and 3 are reversed when going from TA3 to TA4.

So - what do you guys think my next step should be here.  I have choir classes to teach this week and broadcasts to produce, so I don't have a ton of time to devote to this - but I would like to try and get this working by the next home game on 9/17.

Braintrust - what say you?

Yes it is a wiring issue. I'd recommend buying or rewiring the lav mic to TA4 and then building an adapter cable that goes from TA4 to TA3. 

This link on Shure's site allows you to select what type of cable you need and provides you with wiring info

Also the User Guide for the Switch shows you the correct wiring so you can just compare it to TA3 Lav mic and see what you have to do

If your still having issues call Shure Support they are quite helpful 

When this system fails though due to low cost I would suggest to the School a Lectrosonics system which then can be used with the MUTE switch that turns mic off at input it is also super robust but only works with Lectrosonics Transmitters
