I've been wrestling the wild EMU and need some help!  (actually, it has been pretty easy, and fun, in a wierd sort of way).

I purchased the EGT probes with the weld-on bungs from ACS.  The problem is the leads are only about a foot long and they have ring terminals on the ends.  Do I cut these and solder (or weld) extensions so they will reach the EMU box?  Would a standard terminal block work?  Any other solutions?

For the CHT probes, I have drilled a 1/8" hole in the web next to each leading spark plug.  The bottom of the hole stops at the steel liner of the center housing.  I have ordered "J" type thermocouple wire and will tig weld the connections.  My question is... do I need to insulate the junction to prevent it from making contact with the metal housing, or does that matter?  Should I pot these into the holes, or just stick them down into the holes and leave it go at that?
