Low Coolant light is on, and Temperature Gauge is not working.

What is your question?

Both were working until I removed the upper and lower intake manifold to repair a coolant and vacuum leak. I suspect I broke a wire somewhere, I tested the 3 wires coming from the coolant sensor to the harness connection near the Alternator, tested ok. I don't know where the wires go from the low coolant sensor and the coolant temp sensor to the dash. Thanks
