DOES THIS LOOK RIGHT ? Neo 29 CAB JAMMA/MVS switch.

Ok, the seller of the cab I own now a NEO 29 called me back after I left him a voicemail.
He Provided me the PDF of the switch he wired in for the option of JAMMA or MVS.
Now I do understand this dosen't cover the -5v I will be installing that connection myself.

But does this diagram of what's installed on the machine LOOK CORRECT?

(sorry due to PDF size, I COULD NOT HOST IT HERE AT KLOV)

Is there any issues which COULD cause JAMMA OR NEO failures or any HARMFUL issues?
Or does this look like a great idea?. I will upload a couple of pictures that i took today and Let you see the switch in place..

I just want to make sure I can hook up Jamma WITHOUT DAMAGE ?? and NO DAMAGE TO MY NEO BOARDS TOO..

The seller is a nice guy and he is also sending me another joystick because my 1st player one gets stuck to the right. and this is his Handy work or he had it done for him, I just want to make sure this has no design flaws which can cause damage..

PICS coming up.

Nope.

Take out the JAMMA part of the circuit and draw it with the switch replaced by jumper wire and you'll see how the right speaker isn't in the circuit when in MVS mode.
 
Damn it.

Ok, Crap. cause thats what they wired as of now.
i will have to look at what your talking about and rewire this damn thing.
Its been a pain trying to trace every run so far..
and thats what I was afraid I would hear. that it was done wrong :(
I like the idea. but I wanna make sure my cab is done right.
No exceptions I want this thing to last and not kill any boards either..
Damn damn damn damn damn damn damn
Its been a heck of a while, I'm trying to remember how to read the
diagram and trace it to the wires..

wow, even typing that I think wow, I haven't read and remembered how to read
diagrams in some time, and am out of practice. =(

Anyone have a update corrections? options I could do to salvage this set up ?
or is this a Should reconnect everything and start from scratch?
I'm so out of practice and willing to listen to suggestions, input, advice.
HELP! :)

Look close at the board... the traces for all the power connections are passed through from the card edge to the socket, including the -5v power line.
 
ok cool

ok. that's good news so when I get the wire probly tomarrow I should be able to install it. and end up restoring the wire. well solder and heat shrink I guess =)..
now I need to study this thing and find out which wire is supposed to go where when restoring the harness to orig.

Ok Ordered

Ok, I ordered my Jamma adaptor.
now some questions and thank you for the help as well.
For the sake of converting text to a visual that switch Diagram
Numbering the circles left to right
1 2 3
4 5 6

And to make sure I'm doing this correct and thinking of this correct
It should end up as
Wire from Pin 1 (L) on the jamma to Left speaker + side?
Wire from Pin 2 Should connect to (L) But also shows a connection on the diagram to Jamma connector 10?.. Do I remove the Link between Jamma 10 and Left speaker?
Wire from Pin 3 Should connect to Jamma 10 ?
Wire from pin 4 connect to wire on Pin 5 ?
and pin 6 Is where i get a little lost. there is one trace shown on the chart, Yet 2 pink wires in the picture?

does this make any sense at all?.
Trying to follow along, and make sure before I start cutting soldering and heat shrinking that its ok. don't want to start hacking soldering just to go whoops something isnt right.


Easiest way is to restore the cabinet to the proper MVS wiring and use this:
