FINALLY after 1.5 years added the VESS switch (like the European models). No need to pull the dash apart as you can do this thru the fuse panel door.
I would first like to thank mikeselectricstuff and KiwiMe for the schematics and helpful posts to get this accomplished.
So here we go: Begin by removing the connecting plug from the switch panel left side of steering wheel - low (push the interlock tab and pull out plug ) then pull enough cable to work with.
First image shows the proper wire to tap on to, pin 7 of the connector to the switch assembly, green wire - make sure to count from the tab side of the connector.
Next strip a small bit of insulation and solder a 24 AWG stranded about 18 inches long to the green wire, I kept the original green wire maintaining contact with connector (just in case). Not shown is the 200 ohm 1/4 watt resistor which is soldered on that new lead and heat shrink applied, basically new wire lead consists of (9 inches wire, then heat shrink resistor then 9 inches more wire)
Next use some good quality tape (scotch super 33 works well) and wrap around the soldered connection and continue the wrap up the existing sleeve for strain relief.
This is the momentary contact switch I selected - note it has a shaft about 5/8 inch long which will come in handy later. I crimped the wires with loops on the switch and on the lead that goes to ground connection (the one flagged with tape will be going to ground).
Next find a good ground to connect the lead off the other side of the switch - I chose a handy screw holding some module close to the area
Last is to mount the switch. The spot I picked is below the steering column on the right side. The material (plastic) is quite thick there so the longer shaft on the switch I picked works perfectly flush. I might advise to remove the insulation first behind the panel as it wraps around the drill bit

No worry I tucked it back up and all is good.
The operation works really well. The VESS comes on every time you start the car and can be silenced with a momentary push of the button. It can be switched on or off as you desire while in gear and driving as well. I liked the idea of the silence but the problem with pulling the plug at the front of the car is there is times when you do need it ie: backing up in a parking lot etc. This way you can leave it on in that situation and shut it off when you go forward if safe to do so.
Enjoy this mod and sorry it took me so long to come up with this.
