Of course.....the owner can do whatever he/she wants.....the opinion of random guys on the internet is pretty much meaningless.Unless you don’t feel like modifying the harness and putting a computer in a car that didn’t have one, then yeah sure.
My approach to life in general is "live and let live"........when the next generation is swapping Tesla electric motors into gbodies, I will stand back and admire the ingenuity.....you won't hear any "get off my lawn" comments from me.
