Peter,

IF and thats a HUGE IF your thermostat is wired correctly/to the acceptable
standard Red to anything turns that portion of the system on.

Example:
Red and Green = Fan
Red and Orange = reversing valve if so equiped, could be eiter heat or cool
depends on the system.
Red and Yellow = 1st stage cooling
Red and White = 1st stage heat

You should be able to look at your thermostats subbase and confirm that it
is wired correctly before jumping anything. You should have:
Red to Rh and Rc (your 24v feed from the transformer)
Green to G (feeds your fan relay)
Yellow to Y1 (feeds your first stage contactor/time delay circuit)
White to W1 (feeds your gas valve/gun/thermodisks etd etc)

If it's NOT wired like that to a subbase call someone, don't mess with it.
In addition, it appears that you don't know what your doing and you should
stop and call a pro, plain and simple. You mess with it your looking at
several hundred and could be upwards of 1000's (depending on the system) to
replace the components you fry. Simple solution.....place a call to a local
company for probably no more than a cnote will get you someone out there for
this and they will make sure it's done right.

Peter,

I think he answered the question.
C Black/Blue - Common of 24 VAC transformer
G Green - Fan relay

I have yellow, green, white, red, blue wires. The blue wire is not
connected to anything. There is no black wire. That leaves yellow,
green, white, red.

One side of the fan relay is the green wire. The other side is ???
(yellow, white or red).
