Great video. Better that you did show how to fully diagnose it properly by ruling out all other possibilities

So essentially you kept the purple going to the module and spliced in the red and purple from the relay to the purple, the white and brown from the relay spliced to the black on the harnes and the then the small lead to the vts switch?

lack of connection between wires inside (from DC motor) to connector is normal. Inside case are 2 relays, few transistors and bunch of reed switches and resistors. It doesn't indicate that the VTS electronics is faulty. The reed switches are used as position sensor but two of them are also a limit switches. When You bypass them instaling 451M tension in case of holding button too long can damage the worm gear. Thats why i recomnd to repair original electronics.

my vts works fine went through all the tests but when u trim all the way up it locks itself up making unable to go down, the motor isn’t binding in any way it just stops sending power when u want to trim down but sends power to send it up when it’s already up….my question is there’s no other way to fix this problem besides the additional module or replacing the hole thing?

Can u post the color wiring legend?

link to where you bought the relay

How’s the seat working
