May not be possible at this time of year with the lack of sun/warmth outside, but if not, I usually use a heat gun at a distance on the backside to soften the carpet as I am working it, especially around the tunnel area and even more so for cars with 4 speed hump.

Regarding the radio wiring, I found these two articles, don’t know if they might help, but may be worth a look.

* Note: The brown wire may be for an optional Bluetooth module I have seen. It would be nice to have the radio lose about 25 db when the phone is being used. At least, I now know where to go to find the answers I seek.
