One of my future projects. I plan on buying that same unit. Maybe you will inspire me to pull the trigger. Keep the tutorial coming.

Considering how many hydraulic brake light switches I have replaced through the years that is a pretty nice mod right there even if one is not installing cruise control.
I did a similar switch on one of my other cars that uses a stock hydraulic switch -
The switch I used came from Amazon -
https://www.amazon.com/Standard-Motor-Products-SLS...dard+volvo
On the van my cruise cut-out is connected to the brake light itself - only advantage in that is that I can tell when the hydraulic brake light switch has failed because the cruise cannot be shut down by applying the brakes (yikes). I like your approach better. |

I think you'll like it! I'm going to make a final suggestion to go with the wireless switch. Using it allows me to adjust the CC w/out moving my hand from the steering wheel. It makes a convenience even more convenient and I've had years of reliable experience with it in two cars.
That said, it's your van and I'm sure you'll do what's best for it. 
Enjoy!

Jim, thanks for the RF control recommendation but my die is already cast with the wired dash unit. The wired unit will be here Monday.
GoWesty suggests mounting it under the 4 way hazard switch but I have installed a switch there that I use to use to cut off my A/C compressor which allows me to use the rear A/C fans to circulate air without cooling.
Anyway, I plan to mount the wired switch on the left side of the steering column just forward of the Turn Signal switch.
It won't be easy to see the buttons while driving, but there's only two, it can't be too difficult to operate blind.
This grainy photo shows the intended location using green tape.....
I also see that GoWesty has their Speedo mounted VSS back in stock.
I'm sticking with my magnets, in part I have them already, second because my speedo needle jumps so I have concerns about having a jumpy VSS reading as well.
Dave

That looks like a good spot and possibly a bit easier to get to than on the dash.
I've posted this pic elsewhere, but you can see that the buttons aren't visible to the me but I have no problem knowing exactly where they are. For some reason, I think Ford once put buttons on the back of steering wheels (I'm not certain about that though).

Interesting comment about the jumpy needle, my Syncro needle is jumpy and it throws off my Factory cruise as well. Sometimes to the point that it will not engage. Good call on the magnets, I have used them on previous C/C installs and they work great and really do not shift around.
Why not just use one of the two brake light switches as your cut off for the cruise? I can appreciate why VW uses the 2 switches, but most people who own and maintain their Vanagons don't let their brakes not work.
I have never seen one of those fuse taps, a very simple way to get power and not make a mess of your harness.

that spot on the instrument cluster is really nice. I had my Rostra controller there before GW started carrying the unit.
Why not just turn the temp all the way warm while having the fan on?

16CV, Stacy....
I'm using the add on mechanical brake light switch so I don't cut into the factory VW wiring harness. Though I Imagine I can just pull the terminals and piggy back off of them without cutting wires on one of the hydraulic switches.
I may use both, add redundancy disconnect into the system.
Thanks for verifying what I suspected about the jumpy speedo and accurate cruise!
Vanis13, the switch probides a solid shut off of the compressor, be it pulling a long hill or whatever. I imagine the thermostat would work to shut it off to a point depending upon ambiant temperature?
Anyway..........
Step #1
Cut threads on the actuator cable.
Rostra sends some hardware for the cable, two nuts and a "P" ring. These three items are cut with 1/4-20 threads.......
Instructions say to run the nut over the plastic cable to make threads but that seemed laborious, I used a die that tended to mash in threads instead of cut threads.
I also dropped the spare tire carrier and pulled off the spare to gain access to the throttle cable linkage under the pedal.
It has a plastic debris cover over the linkage held on with three short sheet metal screws.......
Remove the screws, the cover slides back on the accelerator cable exposing the linkage..... (White plastic pipe is the accelerator cable)......
I Will be fastening the actuator cable SHEATHING to the accelerator pedal attachment point using the 1/4-20 thread "P" clamp. The threads will give me adjustment.
Just an FYI....... I totally took this mounting to the throttle idea from GoWesty.......
Give credit where credit is due........ I'm not that smart!
Dave
