I had a crazy time putting a 76 cab on a 78 chassis. I came up with a couple different diagrams. One like that one, and this one for a 78, it shows a couple extra wires.

On my swap, after I got it wired up it still wouldn't fire. I was going nuts trying to find out why. Then it occurred to me, the neutral safety switches are different. Up to 76 or 77.5 they are on the column, 77.5-79 they are on the trans. On my 76 cab I found the NSS under the dash, the harness connector is the same as a flat 4 Trailor plug in. So I found a spare Trailor plug, plugged it in and spliced wires till my ignition got voltage. Now I have it taped up, and use it as an antitheft devise. I just pull the plug and it won't start.
