I just did one on my 84. The green went to the HEI, the black went to a ground under the dash. The white went for lights but mine already had aftermarket gauges under the dash so I just tapped into the white wire there. For the red I had to use a male spade and I found a terminal that was hot with the key on. Plugged it in and fired it up and it worked. I`ll see if I can take pic tomorrow if you don`t have it figured out by then.
