Problem with Keyboard replacement for PB15 G4

Hi,

I ordered a replacement keyboard for my MB15 G4. Unfortunately the connector does not line up correctly.

On this model of keyboard there are 2 flat ribbon connectors: one wide one with 26 contacts and one narrow one with 2 contacts. No problems with the 2-contact ribbon.

On the broad ribbon however, the contacts don't line up. I've made a little scheme below. C = contact leads to keyboard, N = contact stops halfway to keyboard, A & B are connected to each other)

Original Part (AEQ43PLG014)
CCCCCCCCCCCCCCCCCCCCCCCCCCANB

Replacement Part (AEQ16PLR033)
NCCCCCCCCCCCCCCCCCCCCCCCNC

Does anyone know the exact contact lineup to make this work?

Cheers - Francis
