Anyone know where i can find the positive wires of the fuel pumps ? I tried those wires under the back seat but i didn't find any positive wire. Thank you in advance!

On that car there is a fuel pump control module.. that feeds the fuel pump in the sender
unit.. not sure what you need that wire for but be careful what you tap off that wire its a
variable signal controled by the module..
