Craig, with some heat in the manifold wiggle the stiff shielded wire coming out of the probe and watch the guage.If the guage moves the wires are broken in the cable. On both my 99 Burb and my 2000 K3500 I came out of the manifold and made a 90deg turn then tie wrapped the cable to a coolant hose that ran along the inner fender nice neat job! So I thought the short length of stiff cable could not handle the engine movement and vibration and the wires inside broke and I lost the EGT guage. When I replaced the probes I tied the stiff wire back to the engine and used the soft flexible lead wire to to handle to movement. It's bad enough I did it once but I did it twice!!! So chalk it up to experience! EXPERIENCE = a whole bunch of mistakes.. Hope this helps Good Luck
