I could try my alldata but as you see i have a 93. I cant imagine them being that much different. so give me a day or so and i will email them to you if you want.
There were no wiring diagrams in my 95 BGB, unfortunately. So I went looking for my 93 wiring diagrams. Pretty dang confusing so I'd need a scanner to send it to you. I feel really bad, so I went looking. Does this help? It's a big file if you're on dial up. http://www.mr2ownersclub.com/online_parts_catalog/1994electrical.pdf
EDIT: As I go through the 93 wiring diagrams, I think I'm understanding a bit more. Only 10 of the 15 pins appear to be populated, if an x on the 3SGTE EA1 connector (at 2,6,9,13,14) instead of a number means it's not used. So far I've found what I think are eight of the pinouts. But there also appear to be some cruise control, abs, factory theft deterrent and Canadian specific items. Let me know what all you have and maybe I can still figure it out. Do you have the original colored wiring?

pain in the ass isnt it. there are indeed no straighforward diagrams. as for what i have so far sorry to say NOTHING 
. however i have no abs and no theft deterrent so you need not worry about those. also the car is imported from the u.s. so canadian specific items need not apply. thanks, when your done or have given up as i have send me what youve got and i will try and work it out.

What a bucket of snakes!
I really recommend you spring for the proper electrical diagram books, but what you do to your car is your responsibility, not mine. Hope this makes sense:
