Oil Pressure?

[Lost815]

I bought a autometer oil presure gauge and it has an oil pressure sender, but I was wonder if any one new where I could find the wire that goes to the evic and gives the information instead of hooking that up, or if someone has already done this mod if they can give som info on how they did it. thanks

The evic display is driven by a module called CCN. The communication is sent across the Can-Bus so there aren't any specific wires just for oil pressure.

for 2.7L & 3.5L, the PCM use an oil pressure switch to determine if oil pressure is above/below a certain threshold. this switch simply grounds the signal wire from PCM.

the 5.7L & 6.1L use an oil pressure sensor to monitor oil pressure. the oil pressure signal wire is at connector C1 pin 20 (violet/gray wire) of PCM. this is a 0-5V circuit.

Hmmmm .... I have EVICS and under "System" I have oil pressure and oil temperature as displays. Interesting to watch the op change with acceleration. And the icons are sorta cool as well.

So can he sort of 't-tap' a pressure fitting in there to run his sensor?

WOuld I just beable to tap that wire to make the presure gauge work? or do I need to install the inclose oil presure sensure? Thanks guys and chkn, where do I find that wire that you mentioned?

[Lost815]

also will the dealer charge me a lot to have them install it? will this void my warrenty

[Rev.Hammer]

It wont void your warrantee and the cost depends if your dealership wants to be a tooth-pullin biutch or not...

[Lost815]

Thanks, but just l;ike it was said can I just tap the wire from the evic, if I can also get the location

[Rev.Hammer]

THAT is some thing that the Mighty FNKYCHKN can answer. I amnot sure about how that would affect the EVIC/ECU setup and whether or not it would be a useful signal to the oil gauge..

[fnkychkn]

first, i would need to know what you drive. YME (year, model, engine).

From past experience, you are going to have to plumb-in a sending unit applicable to the gauge you are installing. They are not fully universal. I like the VDO senders, because you can get "dual" senders that trigger the gauge and the "idiot" light. It saves a tee fitting in some installs.
