Swaping Neckboard

[Arcade-Projects]

Hi,
I have two chassis:
1. Nanao MS8-18A with its Nanao neckboard
2. Nanao MS8-18FB with a Toei neckboard

1st chassis: original neckboard.
2nd chassis: the person who sold it to me added a Toei neckboard to it.

My work is the following:
a. I separated the Nanao neckboard from the MS8-18A chassis.
b. I separated the Toei neckboard from the MS8-18FB chassis.
c. I notified there are some little differences between the two connections between both Nanao chassis (pls see shema below)
d. The Nanao neckboard does have one additional wire that the Toei neckboard don't have.
e. The MS8-18FB chassis connectors are linked togheter by a wire (the MS8-18A chassis don't have this configuration since both of its connectors doesnt have any wire in common).

Can I swap the neckboards with that new wiring like on the 2nd shema?
