Yes, that was him. I can't remember exactly how he did it. I came up with attached but I'm thinking there was a little simpler way. One 5 pin relay would make it easier, maybe...

So I looked over the one 4 pin and one 5 pin setup. Makes the hook up much simpler.

Here's the 4, 5 pin that I came up with. Change around a couple pins and make a couple wires and you're done. Eliminates the stock relay.

After figuring out how to use the VB harness I became a bit obsessed with one that will work with the 69-70 and just plug in. I made up the relay portion last night. After I spend some time on the harnesses I'm building I'll make up the headlight and power portion.

This relay plugs in to and replaces the OEM relay. Then you just hang the hood portion, hook up the power and plug it in to the relays and headlight plugs. When I get done I can make up a how to if you want to build your own. More work than just buying VB one though.

So if you want to make your own harness here's what I made with a modern ATO fuse. Needs tape still. 12 gauge and 14 gauge wire.

I believe I have eliminated all the errors from the drawing. I tested it and it works great.

I second that. I just spent some serious time last night downloading all the wiring diagrams that you have up for 1970. Holy crap. This is an invaluable fountain of knowledge for roadster owners everywhere.

Found them all did you? I aim to please. Wiring problems are a big enough PITA as it is and made 10 times worse if you can't tell where those damn electrons are supposed to be going.

Schematics have their limitations. In high school electronics class it was here's a schematic, now design a circuit board for it.
