12v + for oil light

Post by Stevejoy5 » Tue Apr 28, 2020 12:58 pm

hello guys im fitting an alarm with auto start and am looking for a 12v positive (+) from the oil pressure sensor. As its currently raining im not outside but guessing the wire on pressure switch is (-) so my question is on the dash the oil light must have a + and a - so does anyone know under dash which colour would be +. Im sure i could find it eventually with multimeter but if anyone knows that would help me greatly.
Cheers guys. #lockdownentertainment

You don't say which engine so refer to the wiring diagrams for details and colours for each engine;

Hi sorry its a v6 petrol.
I cant seem to open the diagrams for some reason. I have taken the dash out this afternoon and come to the conclusion that its a constant 12v to all bulbs on dash and its the earths that break so i might be up the creek without a paddle on finding a 12+ from the oil sensor.

Yes you need Flash installed and if using Chrome then google do there best to make it awkward to use and you have to enable the site before it will show you the pages, any other browser is fine.
