I left off today essentially as you see it above. Engine and radiator in and a lot of stuff hooked up. Next thing I'll do is raise it and install the transmission. I may rework the transmission crossmember. It works fine as-is but if I was building the car today I'd do it differently.
The tedious task on deck is modifying the harness and cleaning up the wiring in general. Again, if I were building the car today, I'd do it differently.
As it lays now...

Red is the bundle that went through the firewall (at purple circle) and tapped into an aux fuse panel as well as things like tach feed.
Orange is the ECM connectors. It was mounted just behind the driver's side headlight.
Green is CTS, knock sensor, and oil pressure switch.
White is all the misc. throttle body sensors.
Blue is injector harness.
Yellow is the coil and ignition module.
The two relays are fan and fuel pump. Note the lone blue wire that feeds the pump.
The way I'm planning to change things is by mounting the ECM below the glove box and running injector harness and throttle body related through a hole above the gas pedal. The coils and CTS bundle will go through a hole on the passenger side way high and close to the fender. Should clean up the underhood area considerably. The rest will live under the dash.
The body harness (lights, horns, wipers) is what's wadded up and stuffed inside the white grocery bags on the passenger fender. That will get rewrapped and routed in the factory location.
When the only tool you have is a hammer every problem starts to look like a hippy.
