ICC not working

[Dez096]

Hey guys I’m pretty new to the ford forums just got accepted in thank god I did!! I’m having some trouble with a bf xr8 icc pretty much it was working a few days ago and it was working fine kinda cut in and out but as soon as I smacked the side it would start working again, after a while it completely stopped on me I pulled out the icc and checked all connections were correct and everything looked fine replaced all fuses and relays and that still did nothing at all. Would like to know if there is a certain sequence to put the plugs back in also I’ve put in rear speakers because the car never did come with any and I didn’t earth them would that be causing a short? Also did take out the icc with the battery connected if that would mess with it to? Thanks!!
