I have not done this, so proceed at your own risk.
If it's just the two front windows, pins 4 and 5 in each door connector are for the window motors, polarity dependent on desired direction of travel.
Normally the windows are protected by circuit breaker C1 in the TIPM. Going directly to the plugs as you describe, C1 is out of the circuit. The motors will be protected internally, but if you blow that, I don't know if it will reset, or if you will need a new motor.
So, be careful not to let the motor strain against the down stop if you connect it for going down, and don't let it strain against the up stop when you get it connected for going up.
Also, there is a MUX pin in the connector. Stay away from that pin with the 12 volts. To the best of my knowledge, it's pin 3.
