High2by Posted January 5, 2020 Author Share Posted January 5, 2020 Well, between the sleet and rain today I managed to not fix the oil gauge or fuel gauge. I tried unplugging the oil sensor but the gauge didn't move, it was already pegged out before unplugging it. Then I tried to ground out the wire but all I got was sparks and the connector trying to weld itself to the spot I tried to ground it to. I'm not sure what the next step is. Any thoughts? As for the fuel gauge, I tried the old dash again and it still showed 1/2 tank but honestly I didn't drive the truck that much before I made the swap so I can't say for 100% that the fuel gauge worked correctly before. I think it did but now I'm not so sure. The current fuel gauge is also showing way past the full mark. Is there any test I can do on the gauge to see if it's working? I did check the foil on the back of the new dash and I couldn't see any breaks or bad spots in it. The warning lights "Brake", "Seat Belt" work. All the dash lights work and the tach works. The poor volt gauge shows not much life but I guess it's doing all it can. Link to comment Share on other sites More sharing options...

Remove Fuse (Gauges 7.5A) and try grounding the oil sensor wire again. Something is shorted. Link to comment Share on other sites More sharing options...

This is with the key off/vehicle off, correct? Just making sure. Link to comment Share on other sites More sharing options...

High2by Posted January 5, 2020 Author Share Posted January 5, 2020 Update and end result, I have a functioning oil pressure gauge. Having said that, I'm not entirely happy with myself for going through all of this all because I thought that the PO knew what they were doing. Does anyone know what this 2-wire harness goes to? It's on the passenger side fender well amongst all the other connectors. Power comes from the female side and both wires are constant hot. Solid Red and the other Red/White stripe. Both these wires come from the main harness from the firewall. I ask because the solid red wire was what had been plugged into the oil pressure switch. After not getting anywhere I knew something wasn't right so I went on a wire hunt and actually found the oil pressure sensor wire. It had been tucked up underneath the battery tray out of the way I didn't notice it till I really got to digging. That's why I couldn't get the gauge to react when grounding it out because it wasn't going to the gauge in the first place. I didn't find any blown fuses so I don't know what I hurt by shorting it out. This solid red wire goes to something and I don't know what. When it comes out of the male side of this plug it's a long wire that terminates into what looked like a female end. The Red/White stripe disappears into the loom and I lose it. Whatever the red wire feeds isn't getting any power but I can't find what's NOT working. I will also say that now my volt gauge is reading where it should be but I guess when you remove a dead short from the system, the gauge will read right.

Wire gauge looks heavy. Can't find anything in electrical manual. Link to comment Share on other sites More sharing options...
High2by Posted January 6, 2020 Author Share Posted January 6, 2020 It's a base Pioneer model and it doesn't have a hitch on it but that's not to say that it didn't have one on it at some point. It has the factory front bumper on it too, so I would say no winch. I was looking at some build threads and saw a wire that looked similar to the solid red wire and it was connected to an under the hood light. Could that be it?
