Not sure I'd pull the dash solely to redo the foam, but my vents were spitting out foam crumbs, so it will be super nice to be done with that. I tried to look inside to see if there was anymore hiding in there, and didn't see any, but couldn't say with 100% confidence. If you want some of dr bob's thin foam tape for the upper flap, just let me know.

Do you have enough to do another box?

I have plenty of the dr bob thin foam tape. I can pass it along to you if you want. There's enough on the roll for you and the next 5 guys that want to do this. I don't have any more of the 1/2" foam, but that's much easier to find on Amazon, etc. Not sure if the cloth tape I capped it with is really necessary, but I have a lot of that too. The factory used something similar and it keeps the foam all together. Let me know if you me to send....

I'll sleep better now.

Very professional !!!!

Thanks. I just wanted to get rid of the rat's nest, but may have gotten carried away.

Awesome thread! Love the haircut you gave that power lock box.

Looks great Tom

Thanks and welcome aboard. (Happy to answer questions on the speedobooster too....)

I checked out your speedobooster youtube vid. Very cool device. Do you have to splice it into the wiring or does it go between an existing connector or two?

Also, I've been playing around with arduinos a bit and would love to see the code for the input box with the knobs that you made to get the gauges to move - if you'd be willing to share that. I understand that the code for the speedobooster would be proprietary and I'm not asking you to share that.

I made a device using arduino and wifi module that recognizes when our dryer starts, then after 15 minutes it will send a notification to our cell phones and every 5 minutes thereafter until the dryer stops - this is so my wife doesn't forget that she has clothes in the dryer and therefore doesn't get mad that she just shrunk some of her favorite clothes. LOL

I posted the installation instructions for the SpeedoBooster here:

As you will see, I spliced the wires. If you have an all-original car and didn't want to splice, I'm sure you could come up with some way to intercept the speedometer sensor wire with factory-compatible connectors -- probably right at the sensor. My car is a bit of a test mule so I had no concerns about splicing yet one more wire....

The signal generator box I made is super simple. I'll look, but I'm not sure I still have the code. For the speedometer signal, it's literally the 'blink' example (or maybe blink without delay, I can't remember). The knob is a pot that the Arduino samples to increase/decrease the interval between blinks, if that makes sense. The boost gauge driver is a little more complicated, because it runs on analog voltage. The pot for it is used to create a 0 to 4.5v voltage via PWM and a low-pass filter. Importantly, you need to send the 0-4.5v signal through a 4k resistor (actually 1.9k and 2k in series with a small capacitor in between to ground, which replicates the KLR circuitry). If you want to make one or either let me know and I can help. I also sell the SpeedoBooster if you just want one without the effort. But, if you can make a wireless laundry monitor with text alerts, you can make a SpeedoBooster and gauge signal generator...

How many volts does the blink program send to the speedo? I understand that the more frequently the pulse is generated, the faster the speedo will read but is it just 5 volts for each pulse?

The reason I am interested is I would like to try to make a similar signal box as you have to test cruise control computers without having to put them in the car and go for a drive.
