OK,

I bought a car with a new build 94 single turbo that barley ran. I have the car running amazing now but still have a few annoying issues. The modified single turbo harness had a few electrical issues which I have been able to work out. All except for one that is. The darn coolant level sensor

As of now i have the computer on the drivers side disconnected so the alarm is turned off. Connector near the PS is not on the engine harness anymore. I have tried grounding the Brown/White wire from the main connector, which is the last connector, before it goes into the cabin on the drivers side. Nothing!

I have tried testing for connectivity from the Brown/White wire which is supposed to be the coolant level sensor to pretty much every connector that is in the cabin on the driver side of the car and nothing.

Does anyone know what wire inside the cabin is for the coolant level sensor? I have look through the FSM numerous times and there is nothing that explicitly states where this wire is in the cabin. I am to the point where I need to run the wiring for this sensor directly where it needs to go and the answers does not come up on any type of search that I have done.

Any help would be much appropriated.

 

There should be a white(maybe black-don't remember) connector near the power steering, since it's not part of the main engine harness which is removed when going single or stand alone. Trying running a new wire straight from the sensor to the brown/white wire(from what i remember those colors are correct)not a straight ground. Make sure there's water in there, drove me nuts with 1car forgot there was no water after a rebuild before first start up. Otherwise you're going to have to get the electrical diagram(not the FSM) and find out which wire it is on the back of the gauges. Run a wire from the level sensor inside and to the back of the gauges-you don't want to loose that light+buzzer. I'd find it for you but I have my manual at my friend's shop(300miles away).

 

This is the wire and connector that I described. I tested it by grounding it but my intent is to get the sensor working as intended. Grounding it did not stop the alarm as it should which is why I need to go derictly to the source.

 

the brown/white wire comes from the gauge cluster to the connector near power sterring side on the engine harness, from there it connects to a black wire that is on the emmision harness and ends at the connector on the coolant level sensor.
