gday all ,anyone got a diagram of where i can find tcu in my girlies 92 TR??the ecu has got three plugs into it,its not in built in that unit by any chance??also the diagnostic plug next to the fuse box-how many pins should i see by looking at it front on???any comments appreciated.good bunch of witty,informative guys&girls in here 2 i might add. :D

Engine ECU is located on the LH "A" pillar under the glovebox.

The auto trans TCU is located under the heater box on the floor of the cab,
To get to it remove the trims under the console sides, (elec plugs are on LHS.)
To remove it undo the 8mm head bolts underneath between the backing plate and module (not the 12mm head bolts for the plate to the body)
