The brown and brown/yellow wires were unconnected in the left sided kick panel (where the ac amplifier and relay reside). According the schematics, it’s for the water temperature transmitter and travels to the ac relay and the 15 way block connector. I don’t see anything that it would connect to. Does anyone know where the water temp transmitter resides, what it looks like and what impact it would have on things if not connected.
My problem is a no low or intermediate speed fan. I have continuity in the resistors - so I believe it’s the relay. I haven’t removed the relay yet. But found these wires and decided to go down the jaguar hole.

The brown and brown/yellow wires were unconnected in the left side of the lock panel where the ac amplifier and relay reside.

Does anyone know where the water temp transmitter resides or if I can bypass it ?

 

Also -- for those observant ones who see the cut wires, I did the mod with the aftermarket ac amplifier that relies on the position of the thermostat to determine the AC and Heater role rather than air temp

 

The temp switch is mounted on one of the pipes going to the heater core, part #RTC672 in the illustration below.

The dangling wires with the gray connectors are supposed to be dangling. They're test leads. Jumper them and you'll bypass the switch

Doug to the rescue -- this is a great diagram and I've never seen it before. Test leads? Damn -- I never would have guessed that in a million years. Those are the leads I was referring to.

 

If you want to restore fully automatic climate control, I have developed a cost effective replacement for the amp.
