i have no dials - help !!!!?

i have just been trying to fit a parrot handsfree kit to my 56 plate transit and now i dont have any dials - no rev counter, no speedo and no fuel gage etc - i have checked all the fuses, disconnected the battery and made sure i have not knocked any wires.

any help will be greatly appreciated
