the question is will hooking up the aftermarket temp gauge effect the truck in cold weather / i live in Michigan wear it was just 30 below out any ideas ?

 

no it will not ... its not like a computerized truck ... I run both ...

the electric one in the drivers side head, and the factory gauge temp probe is drivers side just above PS pump on block .... keep in mind ... if you want a better feel for temps ... put the electric temp in where the factory probe spot .... as when I tow I do see a higher temp due to being in the head ...
