oil pressure gauge
trying to wire up my new aftermarket oil pressure gauge....
i have the sender (blue/yellow) connected from the back of the dash to the gauge.
The gauge reads max when the ingition is turned on but reads zero when the cars is started. Just like the warning light. I tried my water temp gauge and it does the same.
Tried the blue/green wire for the warning light so its not me getting it back to front.
you cant run two guages off of one sender because they are resistance driven. sharing the sender would increase resistance and give false readings.
as for the oil sender. you sure youve hooked it up the actual variable pressure sensor part, and not the low pressure switch ?
