I need to double check with a few things below. I would like the windows to roll down to deal with the summer heat.

both windows - cut blu/blk for roll down.

with dei 529t - driver window - blue wire connects to the regulator side blu/blk. brown wire connects to the switch side blu/blk.
with dei 529t - passenger window - green to regulator side. white to switch side.
with dei 529t - orange and orange/black wires are fused together connect to the alarm.
with dei 529t - what are the gray and gray/black wires for?

this is a (-) low voltage. do i need a relay?

anything else that i need to know.

Thanks.

 

Yes you should use a relay. I also recommend usually nissan likes to ground the door controls right in the kick panel (under the door boot, I would ground it there. The closer we could match the resistance on the grounds the less trouble we had. Well unless you wanna go direct to the battery. Also if you have the "anti-pinch" windows they can be a REAL MOTHER EFFER!!!! Check it first I wouldnt even touch the anti pinch ones, but it was very rare to find them!
