Yamaha 704 dual control

[proline 2950]

I am replacing the throttle cable on my proline and have the cable run all the way to the helm and pulled the 704 con*****er and cannot figure out how to get into it to install the new cable. I can't locate any manual on this. Any ideas?

Thanks

there are 2 upper, 1 from each side, and 1 lower phillips screws to remove to split the 2 sides, then the access is under the plastic covers
