This two-piece kit is intended for applications which require an extended lead from the engine to the dash (mini cup cars, for example). It is also ideal for connecting CHT thermocouples to the AiM TC Hub (Part No. MC-223, sold separately).
The CHT thermocouple cable has a male 2-pin flat (yellow K-Type) connector. The adapter cable has a female 2-pin flat connector on one end and a male 3-pin 712 connector on the other. Assembled together, the kit reaches approximately 6 feet (1.8 meters). Fits 14mm spark plugs. 0.7" thick sensing ring.
