4l80e

Im replacing transmissions on my 91 C2500. They are both 4L80E but the "new" one I got has the older 12 pin style plug. My truck has the new style 11 pin plug. Can I just swap the newer style 11 pin internal connector into the "new" transmission I got? Will there be an extra part on "new" trans without a wire going to it since it originally came with 12?
Ive seen threads and suggestions when the truck has the older style pin and the trans has the new style pin. But its the other way around in my case LOL
I was just about to throw it on when I came accross this.
THANKS!
