Stupid Question - Oil Pressure sending unit

[rdoimages]

After relocating my gp controller/relay and the associated harness, I found I had an engine light on and no reading on the oil pressure gauge. Found that the wire from the sending unit had at some point in the past gotten pinched between the block and the bell housing and when I pulled on the harness the already fragile wire broke. So, thinking to myself "well self, that's no problem, you can just fix the wire with an added length of wire since you moved the harness" so listening to myself, I did just that. Of course, looking around my disaster area of a garage, I couldn't find any wire of the exact same gauge, so I used one size smaller. Of course I still have an engine light and no reading on the gauge. Could the size smaller wire really be the problem ?

Probably not.
You need a real gauge anyways.
The factory one is a glorified idiot light. It doesn't read pressure. Once it hits 7 psi it moves the gauge and that's it.

It was working until I broke the wire. I guess I could put a real gauge in the pod on my dash and get rid of the non functioning air filter restriction gauge

Sad truth is our dash gauges really never tell us what is going on. Just ask yourself how warm is my coolant when it reaches the "R" in the word NORMAL. At best our dash gauges are a feel good gauge. Best to get some after market gauges like the 270 degree sweep isspro ev gauges. They are made in electric or mechanical. I ran a mechanical oil pressure on my dash for many years. I now run only electrical gauges in the cab.

Just wish there was a way to do gauges in the dash without cutting it all to bits or having gauge pods all over the place. I saw someone's mod for in dash gauges but that's a bit beyond where I'm comfortable going.

Is there anyone here that can tell me what the set up is on the AST 088 turbo as far as the fittings that are there. I prob need to post a few photos and see if anyone can ID them.

here is my gauge set up. I still don't have a oil pressure gauge yet.

This is what was here when I got it. The pyrometer is non functioning, the boost works, the trans temp appears to work, the filter minder is??.
I could fit a oil pressure in and perhaps one more. It's kind of ugly, but it's a farm truck.

Ugly??

Form follows function and in my eyes its awesome..

Cant get those any more sadly

I think it looks good too.

Maybe I should paint it blue to match the dash and get all my gauges to match brands

Still unable to get the oil pressure gauge to register or get the engine light to go out. It all worked before I moved the harness. It's making me a little nervous.

I think you can just ground it. Lol

Ground the sending unit?

Isspro and auto meters are great gauges I'd mix them.
Oh and a CD player in a farm truck.
