Re: Is this pro wiring?
Looks a bit messy but if all the crimps and terminals are proper it will probably work? Just because the work was done by a "professional" it may not always be right, even though it works, at least for a while. Could be they didn't want to take the extra time to use label's and route it in a neat manner. As mentioned earlier, if it doesn't please you you can walk or re-do it later on your own. If the mounts are solid, fittings tight, no oil or fuel leaks, and it runs well without excessive vibrations that is a place to start.
