Doc's 76 Four Door Valiant
The wires running down through the ammo box are routed through a large grommet that was on the original 2009 RAM 1500 harness. They snake up under the power steering pump and then go under the intake manifold and out the back where they end up at the PCM mounted on top of the trans tunnel. I'll wrap the looms in black cloth Tessa tape and also cover the sections under the intake with a heat shroud to protect them from radiant heat.
All the wires in the photos that are routed down through the ammo box are required to start/run the hemi. The rest of the wires seen coming up and away from the ammo box are for headlights, horns, blinkers, wipers, door locks, etc. I will sort through those to weed out functionality that is not needed for the Valiant and find a way to route the rest so that very little of it will be seen in the engine bay.
