Default 98-99 clock block connector

Need some help, putting a 97 cbr900 motor in a cbr600 f2, I have got hold of a set of 98 clocks. Has anyone got any pictures of the wire sequence in the connector that plugs into the back?
The wiring diagram just shows what colours they are, and every picture I've found on the internet has the cover over the connector.

Thanks Paul.

Are you using the F2 wiring harness for this swap?

Yes, I need to use the 900 spark plug caps as the 600 caps are too short, the coils are the same.

You may have to cut away part of the frame to clear the top of the engine, I have seen bikes that never had to. I took the TPS of the carbs as it should be Ok without it. I bought an offset front sprocket and the chain alignment was spot on.
You will need to use the f3 or 900 radiator. The airbox needs modifying as the engine sits higher

Thanks for posting the pics - that is a really tight fit, are those brackets going to be strong enough?

Yes, there 3mm thick. The right-hand side bracket I doubled up and welded them together.

I have a couple of pictures, maybe they'll help. They're from a 1998 CBR 600F3.

For clarification, are you looking for wiring from the back of F2 or RR clocks? This is from the back of '94 RR clocks on eBay...

It's the RR clocks, My fault, I never made it clear. I have a set of 99 clocks, The block connector on both clocks are the same, just not sure about the wiring.
I have the wiring diagram for the 97 clocks and that shows what wire goes where on the connector. The 99 clocks wiring diagram is vague about which wire goes where.
Once I sort out what wires go where on the 99 clocks I can then figure out the corresponding wires for the 97 clocks, then connect them to the 600 loom.
And hopefully, it doesn't go Cheech & Chong (Up in Smoke).
This is the back of the 99 clocks.
