Wiring a 12volt accessory outlet

Hey im new to the forum its been a big help so far. You guys are great. Anyway Im adding a new 3-way ciggarette adapter into our 1996 Town and County LXI and I want to add this adapter onto the car's Accessories power so its only active when the key is on. What is the best way to wire into that. The adapter i bought originally had an adapter that plugged into the cigarette adapter and then gave you the 3 outlets on the other end. I have cut that existing end off and extended the wire out to the fuse box under the hood but am unsure the best way to wire it in to the accessory power. I do have a 10amp in-line fuse that i already hooked into this wire. Whats the best way to wire it in. Any help would be greatly apprecialted. Thanks Please feel free to email me suggestions too

dismount the under dash (Philips screwdriver and 10mm socket)find a black orange wire .... hook it up there. NEVER APLY PRESSURE TO THE IGNITION SWITCH HARNESS. SERIOUS DAMAGE MAY OCCUR.
