I'm having a problem with my coolant buzzer. I can't locate a leak anywhere and figure that one of these wires is the culprit.

Basically put, my car is a hack job. These random loose wires being pictured are as I've found them. I have no clue as to what they are for or go to. Please help!

Does anyone have any insight? I'm looking at my manual and trying to figure out how this is wired. I'm pretty sure my coolant buzzer wiring was disabled somewhere since the above picture shows that it isn't connected. I was wondering if one of the above pics has that wiring? Or any clue as to what those wires are for?

The car is down until I can figure this out. I may just take it to a shop and have them clean all this up (if they are able to).

Picture one: black with red is your coolant level sensor wire. It connects over by the power steering into a black connector not the white one. The other is your thermoswitch that connects behind the waterpump housing right below the coolant temp sensor.

Picture two:

The black with red connects to picture three. you will need a new sensor as it doesnt seem to have any wire on it. Basically it connects from that sensor to the oil neck and power steering area. It connects on to the Battery/starter harness.

Picture four:

Not sure.

Picture five:

Knock sensor i believe, or power steering.

Fantastic, thank you very much!

The buzzer/light only came on recently, so I'm led to believe that this connection has been bypassed and has somehow failed.

Does anyone else know what these connections are for?

Last pic is the knock sensor. The female side should be somewhere behind the alternator and oil fill neck.

Thank you very much everyone, I've reconnected the knock sensor.



In the process I discovered (what I believe to be) the other end of the coolant level sender off the harness. The female connector is semi-melted. Where does this connect to? Even if I reconnect the sensor side of it, I doubt it'd work:






Regarding the thermoswitch connection. Instead of buying a new sensor and reconnecting it, should I re-wire to a steady power source to keep the fans constantly on?

SO it connects to the sensor on the water pump housing then over to that connector in your hand.

Someone Jakelegged your car !! The wiring you are working on is on page Z-44 of the green manual. You need to restore the wiring properly. Looks like your coolant level sensor wire broke off - get a new one from Ray and re-install it properly.



This wiring you are working on is extremely simple. If you don't have a manual - get one

I had to deal with many customer cars that were that tweaked, I'd recommend you just bite the bullet and replace the EM harness. Last I checked it was ~$800 from mazdatrix and they had a few in stock.

I find this offense lol because my name is Jake....

I'm a bit confused. From my understanding (1) and (2) are supposed to connect to one another. (3) is supposed to go where?

The black plastic connector you've labeled "3" connects to a black plastic connector that is a pain to get at. It's near the power steering pump, you should be able to find it by tracing back the wires that plug into the ignition coils, from what I remember it branches off from the same harness. That wire eventually makes its way to the coolant relays.

I've figured it out. Thanks everyone for the help! It turns out that the last connector (3) for the coolant level sensor was supposed to go into this wire:



That extra ground wire (blue) bypassed the whole system and when it came separated, the buzzer/light came on. I'll be replacing the sensor and reconnecting the loose ends.

As for the Thermoswitch, would it be a better idea to buy a new sensor and reconnect it? OR to put to a constant power source to keep it on at all times?

you can put a spade connector on the thermoswitch wire. It should just plug back into the sensor. That is if the other part of the spade connector isnt still in there.

the sensor on the front of the waterpump housing is supposed to have a white connector that connects at the top of the waterpump housing to another white connector. Then the wire travels over by the power steering and connects to that black connector.

Thanks Twisted7. The sensor is pretty thrashed. It makes me wonder the car's current health with so many sensors undone.

Now I need to figure out my exhaust leak... I don't think I want to try taking off the stock twins. It looks complicated.

Actually, come to think of it. Is there some sort of limp mode that the car would be thrown in if the car senses that it has low coolant?
