Instead of splicing into-- you're going to make a connector right? The other plug is a diagnostic connector or auto tranny harness

Your going to hook up your engine harness to that harness coming from the passe get side... So yes you need it.. Cut the end of the m20 engine harness (connector) and you will need a chassis harness connector from what ever car your new engine is from.

Cut the connector plus a few inches of wires off of your m20 engine harness, then do the same for the m50. Match functions, solder, heat shirk, then go vroom vroom.

Actually, I would suggest doing one wire at a time on the m52 side to avoid too much confusion of a dozen cut wires staring at you.
