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

I went through this several years ago. I put a '74 harness and steering column in my '70 car.

While the main harness was relatively easy to put in, the steering column was not!

Turns out, the mounting subframe is different between early cars and late cars and it required some creative (IMG:style_emoticons/default/sawzall-smiley.gif) and (IMG:style_emoticons/default/smash.gif) to make it fit.
In addition, the steering linkage going down to the steering rack is also different between early and late and i had to re-notch several of the linkage connections to prevent it from binding when turned.

It was a royal pain in the rear ...
