For anyone interested, here's a past thread on these Forums related to the Solar Throttle Controller:
Install was pretty easy, dropped the wires behind the carpet but wanted to mount the controller somewhere that I could see easily. Below the start switch I couldn't see it without turning the wheel (not necessarily a good idea while driving) and in the centre console didn't seem great as I would...

I recently installed one in my 2023 C8 Z51 and I'm enjoying it. I had fun with one part of the install and figured out:
-it was LOTS easier to access and work with the OEM harness behind the gas pedal assembly, by removing the gas pedal assembly (10 mm bolt, "hidden" below a small squarish rubber cover next to the gas pedal). Once the bolt was out, you pull the base of the gas pedal assembly towards the rear of the car, to detach the pedal assembly from the floorboard area
-***to pull apart the OEM male/female harnesses, after pulling up the red "locking tab", ***you needed to press down on the black "tab" which covered the small red locking tab mechanism***. That was the key for me, allowing me to pull them apart. I also found that first practicing on the male/female harnesses supplied by Solar, was helpful (ie. joining them together, then pulling them apart, before working with the OEM harnesses)
-like many others, I didn't leave the small screen installed in the vehicle. I used it the one time, to "pair" the throttle control to my SmartPhone, then since then, I use the phone only
-I hid all the wiring and related components, by stowing them in the cavity behind the gas pedal assembly, which you access through the cut in the carpet
-others did the same, however I noted one person who ran the wire that hooks up to the screen, under the carpet, exiting just to the right of the driver's right knee. That way you could later easily hook up the screen to the wire, if your SmartPhone fails and you need to reprogram it or if you want to sell the car with the Throttle Control and allow the buyer to pair the Throttle Control to his/her SmartPhone. It saves you removing the gas pedal assembly, then fishing the wire out of the cavity. The only downside is having the wire connector visible near the driver's right knee, if someone were to look in that area. So if you want the Solar Throttle Control to be totally "invisible", you tuck 100% of the wiring out of sight.
I've set mine at "Sport 5" and so far, that's working well for me. Hope this helps anyone looking to do this install. Cheers!
