Hey guys I need to know where to put a autometer temperature sending unit.. some one told me just pull the factory....well the car won't run with out factory sender telling the ecm how to adjust air fuel for the emissions effect....I was gonna weld a bong to the opposite side but now carious if that will give a correct reading knowing that it should be flowing the radiated cooled. So I'd probably have to weld it just beneathe the stock sending unit...if any one has any information where to put it without tapping the heads please inform! Oh btw I'm running an 04 mach1 alum. Block .. so if there's a drain plug that I can pull in plcace of an adapter that prolly work best if its closer towards the heads.....:beer:
