Wiring, wideband sensor and intake manifold

Wiring:
The hairiest tasks of all are probably the wiring. Here are some progress pictures from behind the driver's seat:

Oh gosh...

Looking better already...

Here is the completed wiring to the ECU, nicely integrated:

A little bit about the Wideband 0₂ sensor: The purpose of the digital wideband 0₂ sensor is to provide a real-time feedback signal to the MS-3 Pro ECU so it can adjust and provide the perfect air/fuel ratio for any given load. Ed selected the LC-2 wideband sensor from Innovate and I can see why: A review concluded that: ”The Innovate LC-2 has proven time and time again to the be the most accurate, while maintaining amazingly fast response times to changes in air/fuel ratio.”

Passenger side:

The fuel pump relay has been reconfigured with an added relay for the intercooler fan. The coolant temp sensor is also integrated into the MS-3 Pro 3 and the A/C condenser fans are triggered by the A/C like they should:

Engine compartment:

Sensors and boost solenoid have been located behind the stainless cover (not installed in the picture) for a really clean look. No components are added on the firewall (unlike that eye sore of a Delorean starter resistor - ugh!!). Nice and clean! You can also see the little heater hose reducer to interface the car’s heater hose to the engine laying on top.

Intake manifold:

The intake fabrication is coming along nicely. Esthetically speaking, this “round tube” design is much nicer than the square d:o that Ed made for Jeremiah. At least I think so (sorry, Jeremiah J):
