hello drivers so i need some help with my 1984 nissan 300zx, i am installing some gauges and i was connecting my oil presur gauge and when i connect the 12volt power the gauge gos over 100psi and the stock gauge dropps. i connected the the cable to the wire nexted to the oil filter and thats wat it does, i have the digital gauges so i was woundering if i have to run new lines or wat PLEAS HELP thanks

 

With the aftermarket gauge, you have to use there sender.

 

whats wrong with your stock digital cluster?

 

im changing them to aftermarket gauges, and when i connect the sender line from the gauge to the oil pressur sensor (next to the oil filter) the dash reads 0psi and the aftermarket gauge will read past 100 psi. does any one know how to connect aftermarket gauges or has a diagram on how to connect. i have the diagram from the autometer box but its not specific enough.

 

You HAVE to use the autometer sender. run a keyed positive to the positive terminal on the gauge and run a ground and run a wire from the gauge to the autometer sender.

 

wont work i tryed that already, do u think that the gauge has ben damegged or is it that im just not doing it right

 

so you have taken the stock oil pressure sending unit out of the block and replace it with the auto-meter pressure sending unit? was it still reading high? the instructions are all pretty much straight forward.

 

its got the stock oil pressur sensor should i replace it with an aftermarket one to
and if so do u have any suggestions for wat kind i should get.
