I have the G61MPV series furnace.
here is the wiring diagram that is in the furnace manual:
tstat control term. strip outdoor unit
w------W1
r-------R
g-------G
c-------C------------------c
Y2
y-------Y1-----------------y
That is how I have it wired up
The wiring diagram for the outside unit should be in the outdoor unit.....
Maybe your superviser needs to read the manual..

According to the Lennoxdavenet.net , You have to have FOUR wires for the outdoor and indoor to work properly!!!
There is a blue wire in the outdoor unit that tells the A/H it is in second stage. If it is not hooked up it won't work!!!

I will tell my supervisor to get me a 2 cool 1 heat thermostat with dehumidification control. Then the customer will be getting what they sold him.

according to this diagram http://tech.lennoxintl.com/PDFs/535286wia.pdf
there are only 3 wires to hook up on this unit.............
he is working with a gas furnace and straight a/c right?????
you may be thinking of a xc21 unit with the protection module, they need 4 wires.

the guys who done the trim on it were not communicating well with each other. (that is a little obvious though) When I first got there they did not even use the same colors. So, I had to rework all the wiring. I guess I still need to rework all the wiring. This house has 4 units and they are all the same type. So, when I get it figured out I should be able to get the others one right away.

The link I found said 4 wires. But it didn't list them. I found another that did. C, Y1, Y2, and L. L is not used unless a communicating stat is used. Sorry!!
XP16 has the blue wire I was thinking of.

If you don't know, then don't do. If you don't know and still do, then be prepared to pay someone else a lot to undo what you did and then do it right.
If you do know, then do. But do it right. Otherwise, you may not be doing it long.
