Help: CA18DET Conversion on a 1973 Datsun 1200

I have installed a CA18DET engine from an imported japanese Nissan Silvia into my 1973 Datsun 1200 coupe, my main problem is the wiring. The looms were cut leaving a mess of wires to connect with no wiring diagram. Does anyone have any experience wiring these engines or know where I can get my hands on correct diagrams (I had a Nissan 200sx S12 wiring diagram which also had a CA18DET, but the wiring colours didn't match with the engine I have)

hi the best thing to do would be to get a certified auto electy to do it for u because its not real easy u may just have to pay for it weather u like it or not soz couldnt help much more
