Ahhhh, freedom at last.

And, while I've never owned a LAB-X1 ... I think it's possible to cut the trace in-between the header rows, to isolate the pin from the peripherals. Then the peripherals can be wired to any other pin as needed.

I've seen it done before to allow using a 16F84 on the Lab-X1. (ICSP pins are different)

For RC3 its P2 pins 15-16, RC4 is P3 pins 15-16.

HTH,
