First post here. I’m preparing to convert my 89 Westy with a 2.5L naturally aspirated SOHC from a 2003 Legacy. I pulled the harness and it was more of a challenge for me than pulling the engine. The main harness is like a root from a big tree; a main body of wires with tendrils going here, there, and everywhere. Getting to the harness against the firewall was the hardest part for me. The donor was an automatic, so possibly more wires because of that. I’ve sent my harness to Jeff at AutoVentures for conversion. I wouldn’t even think of doing that part myself.?
