Bentley on pages 120-8 shows them both having the same colours, (which you will already know).
Thinking it through, if you get it wrong, all that can happen is that it wont fire.
I dont know what year your car is, but I am picking early 90's as Bentley shows the cam angle sensor being replaced by knock sensors after about '91.

I've seen better, more understandable wiring diagrams.

Good luck! It looks like a nice tidy installation to me!
