That connects the control box and feed to the long duct on the left.

And another on the right. That completes all the heat system ducting, at least under the car.

Another detail: sealing boot for the clutch cable.

While under the car, I was reminded that the speedo cable did not have a boot, so I got out some 3M rubber sealing tape.

Another new boot: for the shift rod. The old one was essentially rigid.

To get that installed, I had to detach the rear shift rod at both ends. Hope this is worth it!

Time to start another task: filling and bleeding the brake system. I bought almost all components, including new stainless steel lines and rebuilt calipers from PMB. The system has been on the car complete for a year, but not filled.

I started with a simple plan, and tried gravity bleeding.

Here's the gravity bleed hose set up on the right rear caliper, with the free end of the hose higher than the reservoir.

I filled the reservoir, opened the caliper bleeder, and...nothing.

I gently pumped the brake pedal a few times and the level dropped a little bit, but then stayed the same.

So, I next got out the power bleeder, that has been part of my garage kit for about 30 years, with the Porsche reservoir adapter.

But the hose is showing its age. For today, I cut off the end with the split and re-attached the cap.

Then I could pump (just air) and pressurize the reservoir to about 25 psi.

Next problem: a puddle on the floor under the master cylinder.

At first I expected to see the supply lines from the reservoir leaking, but they were dry. The (main) leak was from the fitting where the front right line attaches to the banjo fitting. This was actually just finger tight--my bad.

So I tightened that loose fitting, pumped up some pressure, and found more leaks.

Now I was worried. I started tracing all the lines and connections, starting at the MC. None were "loose", but I was able to tighten all of them a bit more. When I installed all the lines I tightened them the way I would for "normal" steel brake lines. I think the SS lines need more pressure to seat fully.

That included the junction fitting inside the tunnel.

I was able to stop all obvious leaks except for where the line feeds into the right rear caliper. Even after what felt like too much torque it still weeped. So I removed the line.
