I connected the bulk head connector to the firewall and mounted the fuse box to the driver fender. I thought the hood was going to hit it when it closed, but it looks like that won't be a problem. I laid out the wiring around the front of the Jeep and it looks like things will all work out.
I then laid out the other harness. I thought it would be easier to work backwards, so I connected the "ends" of the harness first and worked from there. The end of the driver side is an AC plug, a ground on the Power Steering bracket. Then I connected injectors and throttle body plugs. On the passenger side, the end is the various connections to the alternator, followed by injectors. Once that was all laid out, I settled on a location for the trans control module, which will be bolted on the passenger fender. I still need to connect the 10 million plugs to the transmission and transfer case, but it is all laid out.
On one hand, I'm excited because this is a major step toward starting this thing. On the other hand, I'm disappointed because my clean, clutter-free engine bay is not a wire-filled mess. Oh well, such is life. It is only going to get worse once I add a battery, heater hoses, AC hoses, vacuum lines, etc.
Next order of business is cutting the floor so I can install the gas tank and then tackling fuel lines.
