I worked with Technica Race wire to fabricate a harness to my spec and to have future expandability as I play with stuff.
I have designed and fabricated harnesses in the past but am starting to learn that I need to improve my time management and Technica was a joy to use. Anytime I need another harness they will be my go to by far.
I spec'd the harness with a size 24 shell Amphenol "mil spec" connector and booted with Raychem 90 boot on the cabin side. Since I wanted to keep the rear seats and also wanted a fire wall quick disconnect I fabricated a firewall recess out of aluminum to take up the space of the 90's radius. The harness now runs parallel with the firewall and the rear seat backs are retained.
I could have 3d printed it as an easy way out but I wanted to retain a full and true fire proof/resistant firewall and plastic would not have kept that ethos. I did however use it to mock up some designs and after that proof of concept I got to work making it out of aluminum.
The push to connect fitting is there to provide the on board MAP sensor on the Maxxecu with the MAP signal from the intake.
I designed the recess with a plate that provides threaded inserts and the actual recess with the through holes for mounting along with fuel and oil rated, and high heat rated rubber gaskets on both sides to sandwich and seal the firewall access.
Please excuse the mock up phillips head hardware on the photos of the recess. I promise they where not permanent.
