Just stop being difficult, and do what everyone is telling you,

DO NOT CONVERT THE ELECTRONICS TO S5!

Shit will be much easier to do with the S4 electronics.


PS: I totally pulled and rewrapped my body harness, and let me tell you, it is a BITCH unless you really love wiring...

Also, S5 OMP is junk, S5 fuel rail is junk (cant replace just the FPR, need to get a whole rail) and there is generally some other stuff that makes me wish I had an S4 car...

okay, first of all you need to read the thread before commenting.

I will not be using an OMP, the s5 fuel rail doesn't have the same design as the s4 pulsation dampener, which is a plus and my s4 one still works fine.

Pulling the dash out takes about 45 minutes, I've swapped interiors on my car (all blue to all red) and taken out a few FC dashes, you get quicker every time you do it.

or I could re-pin the s5 NA cluster for the s4 harness and use the s4 ECU to run s4 logicon, dash, HVAC stuff, while the s5 runs the EFI. People do this with standalones often.

my s5 harness is in much better condition that my S4 regardless.
