Front wheel speed sensor retrofit ideas?

I'm guessing that means the 6060 doesn't have a speed sensor? I waffled on buying one of those way back when when I swapped the T56 into my car since the T56 had a sensor. The main problem I had was that I wanted to keep the stock speedo and $300+ for one of those boxes just seemed like way too much to me. I'm a tinkerer by nature, so I figured I could build one myself way cheaper. It only took me probably 5+ years and maybe 7 different designs, but I finally got one that is working well that I'm happy enough with and was pretty cheap. It's basically just a tiny motor, an encoder, and a motor controller. I run it off the Raspberry Pi I have in the car that I use like an infotainment system, but you could run it off of a new Pi Pico just as easily if that's all you needed it for. Pretty much right at $100 all told. Motor is ~$25, $8 for the encoder, controller is $60, and a Pi Pico is $4. I think it was another couple of bucks for a cable between them. The motor is small enough it plugs right into the back of the speedo with a 3d printed mount I made. I feed my speed signals to my Megasquirt though and use an output from it to signal the Raspberry. I originally had the Pi reading the signal directly from the sensor before I upgraded my Megasquirt though. All that said, a nice clean box like that is certainly a good solution. I probably spent enough over the years trying to make things work that I could have just bought one to begin with and been done with it.

Sweet!

Correct, the TR6060 does not have a speed sensor. After I asked the question I found that the TR6060 doesn't work with an A-Body anyway unless you either A) convert it to an LS input and midplate so you can use a DS starter, or B) swap to an aftermarket front suspension. Still kind of thinking about a TR6060 with the LS parts but not sure.

What about knocking the spring out of the spededometer and using a stepper motor? Would that make it better? I like the current setup though.

I am planning to run an OEM controller on my 5.7 and have looked at using the built in cruise control logic. Prelim research suggests that the clock spring in the steering column converts the button inputs into messages on the canbus network, so I am thinking about setting up an Arduino chip to convert the inputs from my stock CC buttons on the turn signal into the same messages. I would also use this chip to read the speed sensor (wherever it ends up being) and putting that on the canbus network at the same time. The only other inputs the PCM needs is brake and clutch. After that (in theory), the PCM would control the speed just like it does in the Challenger and much simplify the underhood appearance as no CC canister would be needed.

My other idea had been to also feed the speed signal to either a canbus speedometer or maybe to the Speedbox I linked above. But I like your setup lots more, and not just because it might be cheaper.

Does the Pi Pico need a power down sequence? I was leaning towards Arduino just because there isn't a bootup/shutdown sequence required, as far as I understand.
