autometer gauge problems

[camaro427-69]

just rewired my car (autowire classic update for 69 camaro) and put one of the autometer console bezels in. i use water temp, oil pressure, oil temperature and o2 narrow band. they are all electric sender but act funky. water temp shows high 150 when ignition on and goes up to 180° when car is idling and stays there unless you revv. oil pressure walks up to 50 psi and stays even when engine is hot. oil temp and o2 are not hooked yet.
thanks,
pat

First thing I would check is the ground then I would make sure you are not running the gauges off the wire that's for dimming the interior lights.

hi larry. i checked ground with my multimeter and all the American autowire wires got the function printed on them. i´ve got the interior light on the bulbs, ignition 12V on the + and the sender wires on S...........
