Lads, need to reconnect my cobra alarm I took out a few years ago when I lost both fobs.

Are there any complications in doing this?

It looks like he has cut 3 cables. 2 that are connected to the big pin thing that connects to pic 2 below. Get them soldered? Then he also has cut the cable that connects to Y in pic 1. Didn't see where this was.. Get it soldered too?

I take it TX and RX are pic 4 below?
