Have I been punked? Where are the oil sender and sensor?
I have a slow newbie rage building because every time I do research regarding my 86 4x4 22re Pickup, often nothing matches the pictures I see online. Please look at my attached picture. Apparently I'm supposed to see an oil pressure gauge sensor in that photo, but I see nothing. Could somebody please show me (not tell me), where the oil pressure sensor is for my truck?
Sender vs sensor is one is for a "dummy light" on/off function, and the other gives an actual analog reading (psi etc). Which version you have is based on the gauge cluster you have. If I remember things right, the sender/sensor physically is installed in the same location and uses the same wiring. When people upgrade to the SR5 style tach gauge cluster, it uses the analog oil pressure gauge, while the other options it was just a light.
As for physical location, I don't know off the top of my head, but that bolt in the photo I think is for draining the block for coolant, but I could be wrong.
I'm sure someone else will chime in with a photo. I have an 86 2wd w\o tach, but it's dark atm.
Thank you. I have an actual oil pressure gauge in my dash, but who knows where that dash came from and, for that matter, who knows where the engine is from? I received vague information about my truck at best. Hope you are correct in that others will weigh in. Cheers.
I see, one of the sepcs I see missing in your sig is if the truck is base, DLX, or SR5. Under the hood on the fire wall there's a tag, that has the code to figure it out. I don't think any base truck came factory with a tach, I've seen DLX both with and without tachs. Normally the tach is called an SR5 style cluster, so I suspect most or all SR5's had them. Either case, the tach version is the upgrade, and the actual analog display gives more info than the basic light. I could take a pic of my truck if I remember to. I can probably dig up the wire diagram and see what it says for the sensor vs sender too.
Thanks for the reply, but as you can see from the new photo, there is nothing at all to the right of the oil filter.
That large orange connector leads to a 110 V wall plug, so I'm assuming that's a block heater or something. Also attached is a picture of the oil sensor. So where does it go? In that empty threaded hole to the right? Thanks.

Reason: I used the word "outlet" when I should have written "plug".
Thank you very much, but that doesn't match at all what I see near the oil filter. If you take a look at the first picture I took (looking up at the filter), the only thing that seems like a possibility is that bolt that is partially threaded into that hole directly underneath the filter. My apologies for my slowness here - it should take 20 seconds to find the location, but I'm into hours now on this.

That does look like a pipe Plug at this point what do you have to loose.
The down side is if that plug was forced in the threads might be damaged
Thanks for that, and that leads to the next question. The oil pressure sensor has a tiny little circular top on it, and I have no idea what its connector should look like (Googling it was hopeless). There doesn't seem to be anything dangling in that area. Can someone show me what the connector for that looks like? Thanks.
When it came from the factory it was a single wire connector that slides over the contact on the sending unit and clips in place.
The Connector is a milky white color the wire should be Yellow with a black stripe The yellow/ black wire goes to the gauge in the cluster if you need to make one.
I cleaned the end of the connector and in fact it's green. There are unconnected connectors dangling all through this thing, and also wires with nothing but bare ends and gauges that don't work. I'm afraid I've bitten off far more than I can chew as a beginner. No sense trying to make Thanksgiving dinner if you're having trouble boiling water! Thank you everybody for your help.

It is possible since that plug was in the port someone may have had a Mechanical oil pressure gauge installed and pulled the line and gauge out.
These things take time we will get it figured out .
The joy of not knowing what work the last owners did.
Where do you live real time help could be close at hand If you were close to me I would be glad to help .
I am in eastern Pa close to Allentown Pa.
I will see if I can get a picture !

Reason: because I can!
I appreciate that offer of support very much, but I live in Canada. After many consecutive and unproductive days on this, I think I need to walk away from it and clear my head for a little while. Then I'll decide which direction to go. Thanks again for the assistance!
That connector could be from the AC pump if you have one, it goes to a small sub harness if that's the case. I just started reproducing them, so it's the first connector I saw xD.
It looks like I have the oil sender but nothing plugged into it, I wiped the round top off to make it stand out. My truck is together, so a little hard to get pics.
Better photo, mine has sensor + sender, but sensor plugged in. I do not see the connector for the sender. Toyota likes to use harnesses that work across several options, so your truck has the AC wiring even if it didn't come with AC, same with the california emisssions (EGR etc). At mass scale production, that's normally the cheaper way to design things.
Maybe someone upgraded the cluster in your truck, but didn't hook up the oil sender because it doesn't have the wire for it.
The connector for the sender I'm pretty sure looks like a ring terminal with the tip cut out to "clamp" onto the round surface. Nope, looks like i'm wrong, unless this is a DIY hack to make it work.
I looked up the wire diagram, it does show a connector like that.
The wire diagram doesn't say which trucks used which sensor, but the wire on both goes to the same pin on the gauge cluster, so the same wire is used to convert form one to the other. Note the pin 3 usage for 22r, 22re. Factory analog oil pressure was only optioned for 22re stock trucks it appears like, just a nice little foot note from that diagram. The wire color should be yellow with black stripe that you're looking for.
Here's the connector if the truck didn't have a factory analog gauge.
It looks like I found another adapter harness to build, I wonder how hard it is to get that "J" connector.
Anyway, hopefully the pics helped, no point in giving up quite yet, you're so close to having this figured out and this is a good thread for anyone wanting to switch gauges. The best way to learn is from experience, if you keep going, you'll learn and become better with working on your truck. Most of this stuff isn't hard, but knowing what to do and knowing what things look like etc can be the hard hurdle to get over. I'm learning right along side of you with the help of some google searches and the manuals I have access to.
Looking back over the photos, your connector looks to match mine, I bet someone swapped the gauge cluster in your truck. Not really a bad thing, but it explains a lot too. The faded oil stained wire looks like it should be white/black but the manual says it was yellow/black when new. Here's a bit of a hack adapter, but looks like it would work (might pull off easy though). The image is near the bottom of the page. I'm looking to make the same adapter, but with the factory style connectors so it's more proper.
Sadly my toyota connector manual doesn't show that connector, I'll have to dig around and ping my connector supplier if he's ever seen it before, the DIY home made adapter might be the only option, or find a truck with it factory and get the pig tail to splice on your harness (or put the male terminal on for an adapter harness).
Update, I found a guy making kits for landcruisers, the connector housings must be made yet. The terminal is a perfect match to one I have on hand, I just need to find the housing and I should be able to make the adapter.
I assume you're in Tofino? I'm on the South island, in Sooke, just outside Victoria. I don't make it out that way very often(the last time was just after high school... like 15 years ago.. uh oh, I'm getting old..), but if I do I'll let you know, I'd be happy to lend a hand.
