Rebuiding Inside-out Options

[bkrantz]

The other half stays with the switch, which needs to be installed.

[bkrantz]

Here's the column control module, with the original washer valve, operated by the right lever. IMO not the best idea to route washer fluid into the passenger compartment, through the steering column, and around electrical components.

[bkrantz]

The CarMagic switch replaces the fluid valve, but the end of the switch plunger is narrow, unlike the head on the valve plunger.

[bkrantz]

I decided to cut off the narrow end of the switch plunger, so the equally narrow actuator has a bigger contact target.

[bkrantz]

To make this work, I need to get the switch to sit further into the module, and so drilled a hole large enough for the flange to mount flush onto the module surface.

[bkrantz]

With the switch mounted, I checked the function. The circuit is open, until pulling the lever pushes the plunger, and closes the circuit.

You’ve left no bolt un-turned!!!

[bkrantz]

Last detail: the mounting flange for the switch protrudes beyond the module edge. I trimmed this with a utility knife.

[bkrantz]

Just a small air gap in "resting" state.

[bkrantz]

And when the wiper/washer lever is pulled, it pushes the switch plunger all the way in.

[bkrantz]

Control module inserted into steering column housing, ready for future installation.

Very cool on the pump switch.
I have been making that mod to VWs for a long time.
I recently did it to the Pushbuttons on my Notchback. On my old Ghia I converted the flasher arm to work on the pump, high low beams are on the floor.
I know what I am doing to the 914 now, you are an inspiration (IMG:style_emoticons/default/beerchug.gif)

Yes, the original design here was weak, from sourcing pressurized air from the spare tire to the switch. It's a miracle we have survived for the past 50+ years

btw, great work. what is the projected completion date?

@bkrantz
just read your thread from wo to go over a coupla beers since new years been cancelled here.

my hats off to you.
incredible job.

if you want a detail, the air deflectors bolt up with the bolt from below.
only know this because i stared at them doing the "fool" lines on my car.
they have not been off my car.
not picking on you mate, just nudging your masterpiece.
its a beauty.

i cannot believe the level some of you guys get to with the cars.
and the level this one is being taken to.
its so good to see 914s given this level of love.

correction - you have got those bolts right, i just went out in the garage and looked at mine. i was having a beer induced dislexic moment probably caused by memory of viewing from hoist view below. i remember the flaps are weird, like the bolt goes into the rubber/plastic flap - because i had to undo one to mess around with a fuel line. could not believe no nut was involved.

ignore the idiot.

Thanks, guys. Fun and therapeutic to share (and I have gained much from what others have posted).

I hate thinking about completion dates, but still can't help myself. Some days things go well and quickly, and I imagine just another month or two. Other days, with problems or delays getting parts--or just uncertainty about how I want to do things--I see years of work ahead.

More rationally, I would like to be at least 95% done and drivable by Sept 1 2021. We have our annual big local car show on Labor Day, and it would be great to have my car ready.

A few days ago, I made more progress with brakes, after getting parts like the crush washers for the MC banjo connection. I also cleaned the paint from the front MC output surface.

[bkrantz]

I also got the angled grommets for the brake fluid supply lines.

[bkrantz]

And popped these in place.

[bkrantz]

Now I installed the MC "for real".

[bkrantz]

I also got and installed the circular retaining clips for the tunnel brake line grommets. Not exactly a tight fit.
