I have a 89 honda prelude 2.0SI with about 265,000 miles on it. It runs great, small oil leak somewhere but my main problem is the fuel pump is not getting power. We bought a new relay switch but cannot find the original under the dash. The book says to find the yellow and black wires to find the box. We have looked for 4 hours and cannot find this box to replace it. HELP PLEASE!
