Used a 93 ECU in a 90 and a 90 in a 92

I read all this stuff about switching wires and changeing coil packs and transitor packs in order to use ECUs in differant models but I swaped a 93 into a 90 and it worked. I also put a 90 5 speed in a 93 Auto and it worked fine to. Where did all this stuff about switching coil packs and wires come from?

i have had my 90 for about a year now and recently got another one.

the switching of the wires if for the different things like cam angle sensors went from one black wire to 2 black wires, throtle body setups are completly different, and many more things like transfer case splins and etc...

thats cool if it worked but i have seen 3 people blow 90 ecu in a 92 and up so be careful.
