dont have an engine diagram for your specific car then unfortunately, they dont exist! i can email you a general fusebox diagram for a 90sopec mk2 US spec, which is pretty close except for the engine bits. i have a pre-90 16v engien diagram which will help you figure out the bay wiring, then you could check the fusebox faq to see where the engine wires go to the fusebox

pm me your email address and I'll send you what I have
