I finished the battery positive cable. There will be a couple of adel clamps securing this to the adjacent engine mount tube to prevent the terminals from carrying the full weight of the cable.
I also fabricated the engine ground strap. I used an empty hole near the oil filler neck which required removing all of the paint on the aft side of the boss.
Here is how the cable routes up to the grounding strap. You can also see the battery negative cable here. I can still easily remove the battery without having to loosen any cables.
I also put the fitting on one end of the starter cable. I left the starter cable a little long since I’m not 100% sure of the routing right now. It needs to pass through the same area as the mixture cable and bellcrank, so I want to have that in place before finalizing the routing. You can also see in this shot that I added a washer under the fuel fitting.
I moved the 45º fitting up to the top port in the pressure transducer manifold and installed a 90º fitting in the bottom one for the fuel pressure hose. I also installed a couple of polyethylene hose fittings in the top port. One will route manifold pressure to the Dynon MAP sensor just to the left and the other will route manifold pressure to the Lightspeed electronic ignition.
I also spent a little more time playing with the locations of the various boxes that will mount forward of the subpanel and I think I came up with a layout that I like. Here is where the Dynon EMS box will mount. I separated the sensor wires from the 37 pin connector into one bundle that needs to penetrate the firewall and one that doesn’t.
Here is where I’m planning on mounting the Lightspeed ignition box. This provides convenient routing of the primary ignition wires which will run alongside the battery and main bus power lines.
And here is where I’m thinking of installing the voltage regulator. I can still easily reach the voltage adjustment screw in this position. The only disadvantage is that I need to drill a few more holes in the firewall.
