Contact the instrument manufacturer. With some CHT and EGT gauges the wire itself is part of the sender and cannot be shortened or extended without affecting the accuracy of the gauge.

I'm installing (with the oversight of my A&P) an CHT gauge and need wire to connect the gage to the probes. Aircraft Spruce sells "Falcon EGE" (engine gage extension) wire and they can't tell me if it's the correct thing to use! I couldn't find any tech info on their site and nothing under Falcon. It's my understanding the wire connecting the probe to the readout instrument is sensitive to temperature and that special wire construction optimized for this application would be the best bet. And while I'm asking, what's the best type of wire to use for hooking up instruments? Shielded, unshielded, tefzel, shielded tefzel, etc. Am I asking too much for a generalized answer? Aircraft spruce offers many choices without a definite guideline for making the correct choice. Darick
