Im trying to remove the ect gauge sending unit. The sensor seems fragile, and the covering is cracked at some areas.
How do you remove the cable from it ? Simply by pulling it ? I want to make sure before pulling too hard.

 

That is the temp gauge sensor and yes you just pull it off. It's a 1 wire connector, pops right off. The ECT is actually the 2 wires sensor to the right of the 1 wire you are talking about. The ECT tells the ECU the engine temperature. While the 1 wire only operates a gauge in the cluster for the driver.
