my ecu connector was broken is it okay to use crimp [audio] connectors to connect my replacement connector?

 

bad idea...crimp connectors suck in the first place.having that many together vibrating and moving is bound to work some wires loose no matter how hard you crimp them. its tedious, but solder each one.

 

actually... i dont know how to solder.. how about.. wrapping them then electrical tape them

 

Soldering is really pretty simple. If you spend a few bucks on the soldering iron and some solder, practice on a couple of wires first. I guarantee you will pick it up and be able to solder those connections. It's not hard at all, and its kinda fun.
