All Hondas have one master boot that has all the main interrior accessory wires run through it. It is always behind the master fuse box. Follow the master fuse box to the boot. Then from the inside of the car, using a straightened coat hanger, CAREFULLY poke it through the boot into the engine bay. Tie your wire around it, then pull it back. Now, if you need an accessory line to tap in to, I suggest looking under the drivers side, especially under the steering column. You can also look by the interrior fuse box at the kick pannel. Worse comes to worse, use the acc line at the radio. Your deer deterent has two lines, one for acc and the other for constant 12v, right? Acc lines arent designed for high current applications. If it doesn't, you'll need a relay if you want it to run only when the car is on. Other wise, you'll be blowing fuses all over the place. Just some advice (first hand experience is the best educator )
