I have a 1993 toyota celica gt and i just bought some aftermarket gauges for the dash, just the speedometer and what not, these gauges have a red and black wire running off of them. i know the black wire is to ground the and the red wire is for power. My problem is i cant find a place to plug this red wire into. The instructions said to plug it into a fuse terminal thats hot when my tail lights are on. i cant find a free terminal anywhere in this car. im not even sure if i know what im looking for. can you please help me with this
