look on the battery side of the fire wall. there is a hole that wires go through and it is covered with like a rubber type seal. that's how it is on my s14, i assume it is the same on s13. anyway that's where most shop installers put their wires through. it works, so just cut into it a little ( you have to take off the dash most likely to make it easy to get to) and put the wire through. a friend that can help you would be a great asset. when you're done re seal the rubber thing with electrical tape or silicone or whatever you think is necesary. you dont have to re seal it but i mean it's up to you. hope this helps.
