Thanks, Glenn... MOST helpful. I have everything but the pins that go inside the C7. My (tiny) Radio Shack doesn't carry the box header... may have to scrounge at the elec. supply warehouse for that. The vision of having ALL the ReplayTV codes mapped to my C7 is driving me onward!

Has anyone tried an alternate connection inside the C7 besides a 3x2 pin header? I wondered if a "surface mount 6-connector phone jack" (like you see inside a modem) could be bent and/or mangled and made to fit inside that hole where the pins are... enlarging the hole if necessary? I've also considered soldering a short 6-wire cable with a 6-connector telephone plug to the 6 holes in the C7 and stuffing the cable/plug into the hole where I could "fish" it out when I needed it? It could plug into a 6-connector phone jack on the JP1 box. Etc. Just curious, as my anxiety to complete this project grows a little every day.
