This cable must be used with the MyChron 4 2T temperature sensors. They are 59" long and connect to the back of the guage and into the temp. sensors. There are 2 types of extension cables.
*Please check which patch cable your temperature sensor uses before ordering. (Note: Most H2O Sensors use the 4 prong patch cable, while CHT and EGT use a 2 prong patch cable.)
