The throttle position cable then joins a bunch more wires under the hood to pass through the front firewall bulkhead via an autosport connector and into the cabin to the Motec M150 ECU. The other wires splitting off from the bulkhead connector are responsible for brake and clutch pressure sensors, power and ground for the radiator fan, intercooler pump, air compressor (air lift), and tire temps.
This shot is taken under the dash on the passenger side. The HVAC motor was removed from under the hood, exposing a large rectangular hole into the cabin. The silver metal bracket centered in the photo houses the OEM alarm, airbag, and ABS modules. We removed them to access the firewall to drill the hole for our bulkhead connector (pictured) to pass through.
We have now completed the installation of the Motec M150 and the custom wiring harness from the Zelaya Brothers. The mechanical throttle assembly has been removed in favor of the OEM 1995+ NSX Drive-By-Wire pedal and sensor assembly, and we are ready to turn our attention towards designing a custom crank position sensor and adapting the an 80mm DBW throttle body sourced from a Mustang GT onto our C30 V6 engine so we can finally get it running on this new setup. Stay tuned!

Another Billy cutting-edge NSX project! DBW opens up tons of interesting control possibilities!
The mid to late 90s in between/early years of DBW had so many weird contraptions. I would love to hear about why certain decisions were made for so many parts on cars!
i was thinking the same thing as he was going over the new DBW pedal.
Excited to see this paired with the ECU Master PMU16! Modern brushless fans and pumps are awesome, both in low power consumption and control capabilities. Let me know if you want another set of eyes on your turbo plans.
