Convert to Electric fan

I used a Mark VIII fan and DC Control
Works like a dream. But I do like that Ford Focus dual fan arrangement that Sharkinthewoods has.

Tell you this, I bought the kit with the dual Spals from DeWitts and I've talked to Spal and DeWitts about why the only time they will come on is when I jump a wire from the end of the thermostatic switch to ground. The problem appears to be unsolvable, I even bought a new thermostatic switch, no help. At this point they either don't run at all or they run all the time. When they are on, the engine runs cool all right. Sure would be nice if they worked right. You can chronicle my efforts in my other post:

Mighty expensive upgrade to have everyone stumped on the reasons for malfunction. Answer probably hiding in plain sight, but no one can see it so far.

I am using a dual fan setup from a 97 Camaro. Fit pretty well and was cheap. I am also using fuel injection, so the computer controlls the fans in two speeds.
Low temps or freeway speeds, fans off.
As it heats up, slow fans kick on.
Heats up more and fast fans kick on.
I picked up the fans for $100, relays for about $30. I already had the wire laying around and since it is controlled by the PCM, it just used the stock LS1 temp sender. You would need two temp sensors for the dual speed setup if you were doing it yourself.
I also have a manual override switch under the dash, so I can turn the fans on manually anytime I want.

I have thought of a simple DTDT relay and maybe a SPDT relay hooked up to have one sensor turn on the fans running in series with each other, and if needed run in parallel then by pulling in the DPDT relay.... each fan would draw only 1/2 the voltage and make 1/4 the power/air volume movement, but still maybe enough, then switch to high for a/c or temps....

I found a set of dual spal setup for $130 on CL. Dual 11", shroud, both harness, both relays and the temp switch. All brandnew :-)
I am needing pics of duals on a stock 1968 radiator. Can anyone post pix of their setup?
