Good for extra set of eyes with out having to tear half the vehicle apart. I have found it to be a very good tool here lately. This is a pic of my transmission lines I would have not seen without removing a lot of items.
Yea, that's something I have done several times myself! I use my phone to take pics of parts I need to go pick up, something I'm fixing to disassemble, or for something like installing a belt, before removing the other one.
Yea, definitely makes a great tool for reference or seeing what something looks like that you cant get to, as in your case.
whenever I need to make repairs on an appliance, I always snap a few pics of the wiring harnesses to record what colored wire is plugged in where. Its a life saver when you putting everything back together. A pic is truly worth, a thousand words...
