Wanted to know if i will be able to swap out my s4 bumper with a s5 bumper and be able to connect s5 blinkers and s5 fogs to my s4 wire harness. or will i need to to some sort of macguyver'ing

 

S4 never had factory fogs*, so there's no wiring in place to connect them to.
The bumper and turn signals interchange, I believe.

*The Finish Line lights that have been shown here lately were a dealer installed option and appear to be standard Hella lights, available from anywhere.
They are probably far superior to the S5 factory lamps, which IMO, are useless anyway.

 

Yeah you can definitely do that. Just make sure that you use new reinforces .

Hope I helped!
