PS2 has a internal fan in it and only problems I've had with it so far is draining the car battery...and the 4 point harness works great. It was kind tested out haha...my car broke down and a buddy of mine in a F350 had to tow me home...well a friend was sitting in the old passanger seat that was welded and the weld on the seat bracket broke and he was wearing the harness and it pulled him back...besides, I've tried to pull the shit out of the harness and it doesn't budge
