Long story short---I have an Aerosance FADEC system in my RV6, I need to replace an egt probe which right now is intermittent.  Aerosance has sold out or dissolved to Teledyne Continental Motors.  In the past have gotten probes and splice kit from Aerosance, now TCM wants $450 for one egt probe and a splicing kit.  I think I can do better looking for a type K probe but presently don't know of a source for alumel and chromel pins/sockets to create a splice in the harness.  Also there is a 4 inch piece of braided crimp/heat shrink that goes over the splicing point.  I've not found anything yet--anyone got any ideas?

Unless you have a very high temperature difference across the connector/splice (unlikely), regular pins and sockets will work just fine.  Any error caused by the different materials is non-existent 

unless the two ends of the pin/socket connection are at significantly different temperatures.
