so i got a 78 Subaru brat for $100. the engine that was in it was ran hot so its shot and thats that. the guy i got it from had another Subaru of a different year and took that engine out to put it in mine. so here is the problem i have no spark coming out of the coil. i think i have the power hooked up to it right. i have a new coil and voltage reg in it. the out disruptor has one wire and the new engines has a cord with 3 wires on the end of it. i know right now its all in the wiring and have no idea on what to do or how to hook it all up. i will take so pics when i get back to the shop. if any one can tell me how to bypass anything or what now a big thanks is in order. if theres any info needed you can email me. i.s.a.n.e._.p.r.e.s.t.o.@hotmail.com take the . out
