Med 1 kOhm motstand i releet (usikker på impedansen) meiner eg at 20uF kondiser ser greit ut.

Kjørte ein liten test i Spice(elektronikksimuleringsprogram) med 1kOhm motstand med dette oppsettet (2 porter inn):

Fekk følgende pulser ut på VMON (Voltage monitor) med 1 og 2 sekund intervall mellom stigende og synknde spenning.

Releer slår inn på 5ms, så eg trur dette bør fungere.
Her er logikken på A442 kassen fra LC 80:
Control of Lock-Up System
The ECT ECU has programmed in its memory a lock-up clutch operation pattern for each driving mode
(Normal or Power). Based on this lock-up pattern, the ECU turns lock-up solenoid valve on or off in accordance
with the vehicle speed signals received from the speed sensor and the throttle opening signals
from the the throttle position sensor.
Depending on whether lock-up solenoid valve is on or off, the lock-up relay valve performs changeover
of the fluid passages for the converter pressure acting on the torque converter to engage or disengage
the lock-up clutch.
(Mandatory Cancellation of Lock-Up System)
If any of the following conditions exist, the ECU turns off lock-up solenoid valve to disengage the
lock-up clutch.
(1) The brake light switch comes on (during braking).
(2) The IDL points of the throttle position sensor close (throttle valve fully closed.).
(3) The vehicle speed drops 4 km/h (2 mph) or more below the set speed while the cruise control system
is operating.
(4) The coolant temperature falls below 70°C (1 58°F).
The purpose of (1) and (2) above is to prevent the engine from stalling if the rear wheels lock up.
The purpose of (3) is to cause the torque converter operate to obtain torque multiplication.
The purpose of (4) is both to improve general driveability, and to speed up transmission warm-up.
Also, while the lock-up system is in operation, the ECU will temporarily turn it off during up-shift or
down-shift in order to decrease shifting shock
