You really shouldn't use that cable with an XLR connector, but if

to pins 1 and 3. Be sure to turn the switch on the mic to M or L.
Then plug it in, and when you hear how bad it sounds, you'll have
second thoughts about whether it's worth the time and trouble to
make
the proper cable.

He'll still want it on H because that's only about 150 ohms anyway.
M
and L are something like 50 and 25 and those positions really DO
sound
terrible. If you add some HF eq, the mic sounds a little better.

The Shure published documentation refers to the
"rated" impedence as:
L = 38 ohms
M = 150 ohms
H = 40,000 ohms
