Hi Guys,
I stumbled upon this article while doing some research for my 64 Econo. I don't remember exactly how I got there, but I "discovered" something the Ford Truck guys have known all along. I did this upgrade myself this weekend, and it is exactly the same procedure for our vans.
The required parts are from later Ford Pickups - I used a switch and relay from a 79. I'm going to start stockpiling those parts as I find them, and make them available at my cost to whomever wants them.
Cheers,
Marlon
