[ST202-ST215]

Hi guys, I've got quite a problem, I bought a ST202 Celica with the 3rd Gen 3S-GE engine(RHD), and I've bought a ST215 4th Gen 3S-GTE that was swapped in a canadian 1990 GT Celica (LHD), I have no clue what the wiring of the ST215 is, it doesn't seem too professionally made. And I need the wiring diagrams to make them run, but for some reason anywhere I look I can't find it, and since here in canada we've never had those engines well noone has the diagrams, so I was wondering if anyone would have them or know someone that would have them, thanks. So far we've swapped the engines and the ECU, still gotta swap the wiring but since I don't know much and both cars aren't of the same generation, the fusebox aren't the same at all. Sorry if i'm not clear but english isn't my native language and I don't know much about cars .. Thanks for any help !!
