say you #8 and #6 wires crossed where would it be most noticeable!

 

Yes, it could be extremely noticable, really depends on which wires are crossed. There shouldn't be any reason to have messed up, just double check the wires.
Shoebox's site has the schematic for reference.

I had 2 fuel injector wires crossed and it kept mysteriously setting misfire codes. Didnt notice anything wrong but once I did fix it, i noticed a power improvement.

 

Trust me... it is EXTREMELY noticable. Ask me how i know, lol.

 

I would sure notice it. I think most people would with them being two cylinders apart in the firing order.

 

Yeah, its noticeable.... after installing my custom-fit taylor wires, I accidentally got two of the wires mixed up on the delteq coils......not good...you'll def be able to tell.
