MS123 Crown overdive computer location

[toyobimmer]

HI Folks!
Can anyone tell me where the overdrive computer is located on this car.
It is an early 1984 without an ECT.
Any help appreciated.
Have a good day!

something that old would prob not have an ecu
i know some hiluxs had a transmission relay
basically all it did was convert a neg trigger signal from the overdrive button
to a positive signal down to the overdrive solenoid on the gbox
some hiluxs also had a temp sensor on gbox which would not let overdrive engage
till the auto trans oil got to a certain temp

As said, overdrive is simply turned on and off with a switch, which usually has a temperature switch in series with it to stop the auto using overdrive when it is cold :-)

Cheers
