M50 swap

I got a question for yall and I can’t seem to find an answer. I pulled out a m50b25 non venos from a 91 e34 and now I’m trying to get all the parts to fit right up into my e30 but I got stuck on the engine wiring harness, I have heard many people say the wiring harness from the e34 works but is a little short and tight but still will work. Also heard an engine wiring harness from a m50 e36 works as well and is longer compared to the e34. Now to the question can I use a e36 m50 vanos obd1 engine wiring harness on my non venos m50? Any thing special that I will have to do to make it fit?
