Stepper motors allow driving the original analog gauges. Custom board can control 4pc X27.168 steppers. I'm thinking fue-... battery level, EV motor power %, at the least, maybe something else. Speedo is still analog by cable.

Soldering progress 95% 😊

Procrastinating from making actual progress I accidentally designed a stepper driver board for the instrument cluster with... some additions.

We'll see what comes out of this. 😄

"Dear (public) diary. Today I finished wiring the bus..." 😊

12V system up and running, completely rewired (although based on original schematics).

Custom fuse & relay box installed. ⚡

Printed the outer frame in PETG and used PC for the relay holders for better heat resistance.

Fits in the original location and holds:
• Eaton fusebox for 20 blade fuses
• 5 relays (standard 4 or 5 pin)
• headlight dimmer
• turn signal flasher

Inverter mounted ⚡

Next to find some thick orange cable...

⚡ in finnish we'd say "johtohommissa" 😅

Wiring the main 12V harness.

Of course there's a way of making everything complicated, so in my obsession of avoiding unnecessary splices and connectors I went and bought 90deg "flag" spade connectors for H4 sockets only to find those can't be crimped with normal pliers.

Luckily pliers are cheap and nowadays I know how to use an angle grinder.

Minor progress update again. :)

Got the leaking steering box finally sealed and reinstalled. Steering is working again! Then went on to powder coat and bolt down the gas pedal mount, brake fluid reservoir and finally installed bunch of plugs and made some lasercut cover plates to cover all the (now) unnecessary holes in the floor.

Meanwhile been planning the motor phase connectors and inverter placement. I don't have enough room to comfortably pull the phases out from the top as they normally do, but I *think* I can connect to them from the side via a small maintenance hatch instead. 😏

Sneak peak. Waiting for some parts to arrive, so woodworking for a change meanwhile.

I want a warm wood finish for the interior instead of the original vinyl leather look. Took measurements, lasercut out of baltic birch plywood. Might still add one or two more coats of oil, but already looking a lot like what I planned! 😊 You really learn a lot when doing all on your own! ...but it's a very slow progress. 😂
