Pretending to make a '75 wiring harness a 1970 wiring harness, got a '75 wiring harness in a '70 chasis Options

[buck toenges]

So I went to hook up the fuel pump of my '70 914 and couldn't find the ground and power wires off the main harness. Car had carbs and I decided to go back to F.I. you know old school. Snooped around and found out I have a newer harness then stock. I also have a newer steering column then stock.

What I need to know is: since the relay board 14 pin plug is only using 12 pins can I just hook up 2 more wires and pretend it is a '70 wiring harness for the fuel pump to be back in the engine bay ? How do I reroute or change the relay plug to get a ground and power wire back to the fuel pump?

I want to keep the fuel pump back in engine compartment. I don't have a diagram that tells me how the 14 pin plug is wired differently in a 75 then in a 70. I just replaced the fuel lines with s.s. and just bought a new 3 port fuel pump.

Finally, can somebody tell me what is the color of the fog light wires from a '75?

Thanks,
Buck
