Hi, hector- do you mean the Hood Release?
That involves taking off that frnt valance in front of the radiator, the right headlight assy, under the electrical box, and following it back through the firewall. Start at the valance, the plastic one first, then the steel radiator support valance, and disconnect the hood latch from the steel support. Un hook the cable from the latch and begin to pull it back. As a safety measure, you might want to disconnect the battery so nothing can short out. Under the dash, un hook it from the back of the e-pedal and reverse the procedure for reassembly. Tedious, yes. Impossible, no. Good luck!
