Low next to the toe boards on the firewall (not actually through the toe boards?) on either side for the light wires and behind the distributor up higher for the engine harness?

I was only thinking about the engine wiring right now (don't have the rest of the wiring right now anyway). I have a chevy, but the distributor isn't where it should be its on the front of the engine , but lower under the water pump...not the like Fords . so if I run the engine wiring up there it will be a huge eye sore hmm..
