Installing back bone

[Goldog]

I have currently a C125 hooked into a DSM300 and a B60 20 degree transducer, also a CP100 hooked to a CPT-100 transducer, RD418HD, HS5 hooking them together ( I have one connector still open for the new MFD). The VHS is an ICOM hooked to the C125 to give the GPS location to the VHS. I will be putting a 2nd MFD E127 in also. I want to hook up the Suzuki 2006 250hp computer to feed the engine info to the MFD. The Suzuki dealer is telling me to put a Suzuki backbone in and hook the computer from the engine into that and then to the Raymarine system will it connect? If I use a Raymarine backbone I am worried about the Suzuki connectors from the engine will not connect to Raymarine backbone connectors.
