Where Is The Auto Trans Computer On A Series Ii R31?

[busboy]

Hello, help needed please.

The conversion of my Toyota Coaster to RB30 power is going well, but I can not find the computer that controls the auto.

I have a series II 1988 Skyline for a donor car, and i have the engine and trans out and sitting under the bus. Got the eccu computer and wiring loom out cleanly enough (and remembered to label most of the connections so I have a chance of reconnecting it again) but for the life of me I can not find the computer that controls the auto.

According to the Gregory's manual I have, it is under the passenger seat. Well, if they are right is must be the size of a pin, or somebody pinched it. If it was pinched then all I can say is the auto worked pretty well without it!

I traced the wiring from the auto into the panel work at the front of the car behind the battery, but i can't see where it goes from there without using an angle grinder to get behind the panel. (A bit rusted on.)

Am I missing something here? Is it part of the ECCU or is the computer internal?

my r31 auto had a big ecu thing under the passenger seat, i assumed it was for the auto trans?
