Here is 71 Cuda resto-mod that I did for a customer,
Having a big o fat Hemi helped to hide everything.
I ran the front body wiring under the drivers fender and the motor harness through the firewall right behind the motor. Controllers went under the dash. I made all the harnesses.
A/C lines I ran down along the frame rails.
Heater lines across the top of the intake manifold.
Has Fast EFI and ran the fuel lines up the backside of the motor.
