Blower will not come on during AC

I just replaced the furnace blower in my Lennox G8. The fan blower comes on when T-stat is turned to heating. However when I turn it on AC blower will not come on. The Trane unit outside is running but the blow won't.
The relay is a Idec SHIB-05.
I think I may not have one of the wires hooked up to the relay right.

G8 ? G81 perhaps?
Very old. Standing Pilot?

Could you post close-up pics of the main controls and their wires?
