all warning lights! help!

[3yaris]

help! newbie here,i was looking for a 12v ign on feed,and tapped into what i now found out is cruise control clutch cancelling switch,of which i have an automatic.so,this is not being used.the car is a 2010 yaris 4 door,what happened was i checked circuits to find a 12 hot feed with key on,and found this one.well,went to clip the wire to splice in a connector,and a little zap.now the car has no power stg,no trac control,no speedo,no odometer,no abs,no overdrive,tire press warning light on,check eng light on,along with the aforementioned items also.what could i have possibly blown?checked all fuses,relays,even the big fuse link off the batt feed under the hood.all good.any help on this would be greatly appreciated.thanks
