Engine wiring harness - easy to replace?

[FLJetBoater]

As the topic states…..curious if it’s just a matter of disconnecting existing one and connecting new one in its place and zip tie down? Do the harnesses come with the wire protectors on them or do they have to be added after?

i did a repair on a single cylinders wires last year but seems that has failed again so figure it’s worth just replacing it

After doing some research... It can take an hour or 20... In my experience I cant even change out a pisser water port in 3 hours. What ever you decide... good luck.
