Oil Temp Indicator = Oil Temp Sender/Sensor? Options

[torakki]

I'm trying to track down a temperature issue on our 2.0L, and have replaced the gauge and sender. Temp still goes to red (about 280F), within 10 minutes of driving. Temp is actually around 165F from a laser temp reader. Only thing I can think of is wiring.
Am I correct, when I see the wiring diagram showing the Oil temp indicator is the same as the sensor? The diagram shows an "indicator" and a "gauge". I want to run some external, new wires to see if there's a difference. Thanks for any knowledge.

Looks like the new schematic from Jeff match's what I'm seeing in the car. And the sensor is a 200C which is what the original was that should match the gauge which matches the '74 car. I started stringing some wire and connectors together so if it's not too hot tomorrow, I'll play car tetras, get it in the garage and run some new wire. That's a good idea about getting the reading off the filter. Thinner metal should heat up quicker. I'll post updates when I finally get it tested. Here's the readings and it was about 2 minutes after shutting the engine off.
