okay so i swapped in a new good s5 chassis harness
okay
thing is
my car wont start now
okay
so like with the battery on
the lights on the doors light up
so does my tach
but nothing else lights up
thing is
that i found that the main fuse 100a was blown
so im going to switch it
think that should do the trick?
gurus hit me up

 

I thought the main fuse is an 80 amp? Tat would def make it not start.
