anyone have any experience installing one of these? All instructions I've seen are kind of vague....on a 98'runner, the ECU is behind the glove box right? take that off, then it's behind the heater duct?

anyone know of a good tuner in orange county, ca?

 

I have installed one on my 99 and the ECU is behind the glove box. Did you buy it from URD? - If so it should have came with a vehicle specific install sheet that tells you all the wires you need to splice into. If not, you will need a factory service manual to get the right wires / colors and thier functions from. It is a very easy install once you find the correct wires.
