dei 530t

When you turn off your ign, do the switches in the driver's door stay live with one touch operation for about a minute? Then the motors probably have 3 wires, ign, ground and data if so these are your options. Look for any motor wires (2 red and another colour in a sleeve)outside the motor housing. If they are not there, its still do-able but without the 530t. Make the ign wires both sides permanent using a relay (25amps to 87 and 86,  87a to inition source, 30 to windows and 85 as a pulsed output from the alarm open up the motor housing, power up and you will see that grounding (via a test light) two circuit points on the board near the motor connections will raise and lower the window. Use a 2nd pulsed output suitably diode isolated from the first you could time it at about 5secs to raise the windows energising the same relay. DO NOT REMOVE MOTOR FROM MECH, if you do everything will be out of alignment, adjustment is a swine and you might pay $360 per motor.

If you have 2 wires going to each motor, then these are your motor wires, one in each motor, red is up on passenger side and down on drivers side but check.
