The #17 fuse is hot in start, bulb check, and run. It uses a pink and black wire. It goes to the diagnostic reserve module, torque converter clutch/cruise release switch, twilight sentinel, audio alarm module, electronic compass, rear defogger relay timer, fluid warning center, low coolant module, instrument cluster, height sensor, and headlight switch illumination lamp. If you unhook all of them, and start plugging them back in one by one, when you get to the erroneous one, it will blow the fuse.
