I cannot but I did splice the big power to glow plug wires together outside of the connector. And I have the glow plugs on a switch inside the truck so it still runs I just have no gauges.. oil pressure or coolant sensor and I think it’s messing with the cold advance and just all the wiring to the engine

Best way with that plug is outside the connector with the large wires.
Have you checked all your fusible links?

The Oil Pressure sender is on the back of the engine on the drivers side. Has one wire connected to it.
Temp sender is on the front drivers side.
At the end of the GP Harness (drivers side) you will see two single wires that split off to a sender. one is the temp sender for the gauge.
Sender could be bad or wire disconnected.
