The THP2.5 uses a regular 15-pin D-connector, whereas the K3 uses the 15-pin HD D-connector. Nothing special needs to be done, other than finding the pin outs from the manuals. The THP 2.5 even has pull-up resistors so early K3 radios will drive the band data input just fine (NOT the case with the THP 1.5, where you need the K3 pull-up mod). If you plan on using ALC, you do need the K3 negative-going ALC mod if you have an early K3.
