We got the motor in.... but have some problems now
We got the 13B n/a into my 1990 FC last night, it runs fine, timing is dead on, but i do have a couple of problems....
1. There is one connector that we could not find where it went. It is a round black connector going to a green wire with a black stripe. When we took the car to my buddy's shop, and pulled the code 9 that the engine had thrown, we found out that this was the thermosensor for the ecm... however, we cannot find anywhere where this would plug in, not anywhere around the water pump.
2. We have a coolant leak.... possibly related to the sensor problem, as it is coming from somewhere on the top of the motor. We're pulling the top end off again tonight to find out where exactly...
3. Speedometer doesn't work...... ?
4. Fuel level gauge doesn't work either... upon searching it seems i have to reground the tank?? How is this done?
thanks guys

The ECU thermosensor is a completely different beast, not related to the fan thermoswitch at all, other than being in about the same location. If you have an error code for it, make sure the connector is secure. Follow the procedure for that error code in the FSM.

You about the one millionth person to ask about this... It's for the thermoswitch on the back of the water pump, next to the ECU thermosensor. It controls the auxiliary electric fan in front of the radiator. If the car didn't come with the fan, then it won't have the switch either, so the connector is unused.
Don't even know if it works, because the tank was empty when i got the car a few months ago, and the engine was blown.... this is the first time it has ran for me... the fuel pump works fine though

Some people claim to be able to reach around and undo the gauge-end connector but since my hands are three dimensional, I can't. Undo the cable at the transmission and push some slack through the firewall and the cluster is much easier to disconnect.

The water thermosensor has two wires. One is green/white and the other black (in some cases brown/black).
The grounding of the fuel tank was a hoot.
The auxillary fan would be located in front of the air conditioners condenser or in front of the radiator. Small six to seven inch fan. Electric.
And I put some suggestions on your other thread in the other forum.

The sending unit for the water temp gauge is on the driver's side of the engine, very near the oil pressure sending unit. Look just in front of and below the oil filter pedestal.
The speedo cable is what is hanging you up- NOT the electrical connections.

I'll check it.... i tried to pull the gauge cluster out yesterday, but it doesn't come out far enough? I'm guessing the wires are at their max length behind the cluster...
... is there no way i can get behind the cluster without taking the whole dash apart?
