quick question

i aquired a complete wire harness from a 1.6L coupe Ex, i want to put it in my 93 dx hb so i can install my power windows, my question is, will this wire harness from an coupe ex fit in my hb and if it does will there be any problems. i was thinking that there wouldnt be considering the thing that controls the car is the ecu. my other thought was just cutting off the wiring i need and wiring it into my current wiring harness any help would be appreciated
