Can I extend the wires to get it up to the front of my diesel motor home?

Asked by: Tractormel
Hi there, thank you for contacting us. Anything beyond the 10 feet of probe wire that comes with the 3344 would require a special extension module, model 5257: https://www.autometer.com/module-wiring-extension-for-stepper-motor-incandescent-pyrometer-gauges.html Please note if this is an older existing gauge, you may require extension module 5256. This would be used on the earlier style gauge that features a single red and black power wire coming from a grommet on the gauge as opposed to a black, 10 pin removable plug that incorporates the power wires on the current style gauge.

bought this gauge for my gm 6.2 diesel w/banks turbo the threads on the probe arent the same as the thread in manifold. what thread size is the probe? if I bought a thread adapter would that affect the accuracy? thanks

Asked by: mowerdave
Hi Dave, thank you for the question. The thread size of the adapter on the 3344 Probe is 1/8" NPT. An adapter could be used as long as it still allows the probe end to protrude into the exhaust.
