The switches inside still continue to work.
I got the lock button to function on the key fob but not unlock
Wired the 451m according to what was listed in the manual :
"wiring diagram c directly wired reversing polarity switch circuits."
I chose to wire the banvie as a negative trigger
As far as I understand it that's how it should be set up.but it doesn't unlock...

Have you tested and verified an unlock output from your Banvie unit?

I had mistakenly tied into the orange/violet wire and the pink/violet wire and this must have put me in between the switches. I now am tied into the orange/black wire and the pink/black wire so now I'm in between the passenger switch and the motor. But it still didn't work. I swapped out the banvie unit out of another truck and low and behold it works! Thank you😁 I must have fried my banvie before I got the 451m

Oops seems I've jumped the gun. only the driver side gets unlocked with the key fob not the passenger side

Okay so I've tried wiring the Banvie and the 451m relay to the passenger side and now the passenger side works with a 30 amp fuse. driver's side does not work. it seems to have less power wired on the passenger side

Okay got it fixed.The orange/voilet and pink violet on the driver's side are the ones to cut into for anyone who wants to know.
