I cut the wires to the exact lengths indicated in the manual (Black 4 5/16″, Red and Brown 2 3/4″). After mounting on the chassis, I realized they were too short. Upon review of the video and pics in the manual, it looks like the transformer was assembled upside down at the factory with the wires coming out of the top. See picture.
Thanks for your help
