As another example of how everything is interconnected, the arbitrary goal is to start the engine, even if for just a few seconds. To do that requires all the engine wiring, which means shortening the harness and placing the ECU, but it would be good to have the fuse block in place, which is to go in the dash somewhere, dictated by where the instruments are not. That requires figuring out where the instruments go, since their placement is more important than the fuse box, and on and on.

Laying out the instruments consumed the entire day. It’s pretty cool how little room the flat dash consumes. In addition are the usual switches: lights, turn signals, wipers, ignition, hazard, horn, fan, fuel pump, and a couple spares. The cross-hatching is area either blocked by the steering wheel or unavailable due to the support frame. It ensures everything is both visible and easy to reach. It’s hard to see but most of the switches are in pencil to the right of the steering wheel. Not sure where to mount the big heavy duty battery switch. It may go just below the dash and ahead of the shifter.

The right side of the dash is left blank for a real, actual, working glove box. Inside it will be the fuse block, relays, and space for glasses, papers, etc.

My buddy Cecil dropped by and asked how I was going to install the dash cover without risking cracking the paint. I don’t know. Worst case, the split in the dash, which currently allows slipping it around the tubes, can be extended all the way across, making the dash three pieces. That makes it trivial to install, but leave two odd-shaped end pieces that I’m not sure how well will integrate.

One solution is make the dash cover in steel and weld it in permanently, not sure why I didn’t think of that. It avoids needing rivets at all, but also means the dash will be the same color as the tube-frame chassis and I’m not sure builders want that – I don’t. Still, it would make things much easier, though there’s always concern about paint coverage in the corners and overlaps.

Anyway, in other news, the A-arm patterns are being made – that’ll save a bunch of time on setting up the fixtures.
