A sheath containing a white wire and a white with red (or orange?) stripe plus a seperately bound green wire extends into the engine compartment from the front valence near the coil. The white and white w/stripe have right angle connectors at their ends. These wires were not connected to anything when I bought the car. What are they for and where should they be connected?

Are you sure about the colors? I just took a look at mine, and there is a green wire with a blue stripe (very subtle color difference), a white, and a grey with a red stripe. The green/blue goes to the temp. sending unit; the other two are for the electric fans (sending unit on side of radiator).

The blue/green wire is for the temp sending unit.(front of the manifold next to the thermostat housing pointing forward) The white and white with red stripe go to the fan switch.(mounted on top of the manifold just behind the thermostat housing/water neck pointing up). There are two fan switches. One on the manifold and one on the radiator. One for low speed. One for high speed.
 
Re: Mickey Richaud

Mickey, thanks for the reply. You are right about the colors. The green/blue does go to the temp. sending unit. I can find the radiator sending unit on the driver's side of the radiator, but the wires are already there and the two in question are too short to reach. The wiring diagram shows white and gray/red going to "A/C high pressure" switch and also "high temp manifold switch" but I can't find any such switches within reaching distance of these two wires. I have an Offy intake manifold; could the original have the high temp manifold switch? If so, could these two wires be connected to a manual switch to operate the left radiator fan?
 
Re: tr8todd

tr8todd, my Offy manifold doesn't have the switch behind the thermostat housing; it does have a nipple with a hose attached going to the coolant expansion tank and the temp sender switch.
 
Re: tr8todd

Sorry - my earlier post wasn't clear. (Must have been turkey overload!)

The stock carb manifold has a two-terminal switch near the front, on the top of the manifold. I believe that's the one Todd mentioned. That's where those two wires hook up. The two wires control low and high speed on the fans. Mine is the Edelbrock manifold - no place to mount the switch. So what I did was hook the slate/red and the white wires to the wires coming off the switch on the side of the radiator - spliced the slate/red to the light green/white, and the white to white. This way the fans run at high speed when called for.

Thanks, Mickey, that makes sense. Looking at the wiring diagram, I think only the slate/red needs to be spliced in to the light green/ white; the two whites both come from the same source, the ballast assembly. The choice seems to be either run both fans together off the rad switch, or connect the left fan to be run manually with a dash switch.
