Steve, the orange wire goes to J 910 (J10) on the system audio sq. board,
but it looks like
this is just a connecting point (Holding point) as it does not connect to
anything on that board.
J10 is just above the center of J6 which is a 6 pin strip connector at the
edge of the board.
There are two strip connectors on that side of the board, and J6 is on the
left when the second one J5 is on the right.
To the right of J5 are a bunch of wire connections H11 to H17
The interconnect page shows a dotted line from the orange wire that would be
on J10 to the
channel guard board J1001. I presume that this is a mod if you add channel
guard.
It is labelled as Channel Guard disable
I have quite a bunch of these MVP's so if this info doesn't help
I can open one up and have a look.

Hi John,

front panelwhere does it hook up there??

Subject: [Repeater-Builder] MVP problem
Hello all,
A friend gave me his MVP UHF repeater to work on. The audio squelch
board
was bad and I replaced it. I made what I HOPE was all the tracings and
jumper connections on this board by copying the old board. The problem
is
that there is NO audio on the transmitter output when the squelch is
opened up. I can hear squelch fine on the transmit output when I press
the
TEST switch on the front. The squelch control has no effect of course
on
the squelch while in the test position. There is an ORANGE wire that is
connected to this switch on the front but is not connected-like it is
broken off from the board. Does this have anything to do with the
squelch?
The repeater keys up fine when I open the squelch but no squelch noise
is
present-like it is being muted. When I press the test switch I can hear
my
audio on a monitor receiver fine when I transmit thru the repeater with
my
hand held. WHERE does this orange wire from the switch go? Is this the
problem?
Thanks for any help!
