Engine wiring diagram for 97' Dodge Cummins

[Justinb]

Hello all,

Any one know where I can get a engine wiring diagram specific to the 1997 Dodge Cummins? I have looked at Google Images and I cannot find anything specific to that truck.

My oil gauge stopped working in the dash when I replaced the power steering pump and broke the old sensor and when I replaced the sensor it still doesn't work. So, I need to find out what the circuit is doing and what wire is a ground if at all. I started tracing the wire down and found there is more than one sensor on the same circuit so I need a schematic. Any help would be appreciated.

Cheapest is to sign up for a monthly subscription to mopar1973man.com and it's in the download section.

Cost like $5 a month you need to be a paid member for that area.

Or purchase one from Geno's Garage, Amazon, or Tech Authority.

Ok thank you

I looked through my Chilton and Haynes manuals for the 94-96 models. The Haynes manual has a schematic, but I do not see the oil pressure sensor cited.

If you're planning on keeping the truck I'd look into a set of these.

They also carry the CD version for $36.00

Also going by memory there are 2 types of oil pressure sending units. But obviously if you got the wrong one by accident, it wouldn't jive with the plug in harness.

I'm pretty sure it's something simple.

The 5vdc supply wire taps off to other sensors but the reading wire is seperate.

Yes I did buy the wrong oil pressure sensor at first but genos garage replaced it at a discount for me. So it’s actually plugged into the harness and it still doesn’t work. Need to figure it out. Thanks guys

Now that I think of it I don't think you can PM since the site upgrade. I believe now you have to start a conversation. Same thing, click on the user name and select start a conversation.

I tried to start a "conversation" with JustinB a few days ago to share a Service Manual with him but don't think the message ever got through or someting else. I couldn't add a link to the manual in the message, so just told him to send me his email?
He should still buy a paper FSM from Genos. IMO there is nothing like being able to turn pages when in the shop, greasy fingerprints and all. You can always tell what problems / mods I have had with my vehicles by the pages with the grease marks. No library queens in my shop!

I learned the hard way that when you make a revision in wiring, MAKE A NOTE OF IT!!!!!! I got tired of having to run through a cycle LONG ago just to roll down, or up, the windows. Still know what I did and what revisions I made. When I photocopy it for a friend, the revision goes with it.

Yep, I have both the paper, and the CD version. I would hate to part with either.

Looks like the moderator finally approved my link to the 97 FSM, it is now active in post #5, if anyone is looking. I didn't create the file or link site, so not sure how long it will be around.
