It's time for the conclusion of the Vintage Air installation on my '76 Mazda Cosmo. Yep, it's episode 31! Part 1 and part 2 covered the mechanical components and plumbing. Part 3 concentrates on wiring up the system, installing the ducting after adapting the stock Cosmo dash vents, and then powering up the system for electrical testing. I also explain a bit about how the MegaSquirt MS3-Pro handles the A/C system. It sure feels good to have it all done and I'm happy with how well I was able to integrate it into the car. Of course the final testing will have to wait until the system is charged and the car is running. Included in this episode: wiring the Vintage Air system, modifying Vintage Air harness to work with EFI/MegaSquirt, WeatherPack connectors, modifying Cosmo dash vents using Vintage Air adapters, cutting/bending/forming aluminium, electrical checks and testing.
