Hey guys...I got a problem I was hoping someone might be able to help me with...

After I installed my new springs/shocks on my 98 GS-R I noticed my ABS light was on. I had the diagnostic test done to find out my left rear wheel speed sensor was damaged. The dealership wants $350 to fix it ($130 part/$220 for 2.5 hrs labor). I bought the part from them (since I need it anyway) and I had them print me out the diagram to show where the part goes. Unfortunately, the diagram is really bad so I can't really tell where it is located. It looks like it might be under the gas tank somewhere.

Does anyone know where the part is installed? Is it really a 2.5 hour job? Its a dinky little plug/wire so I can't imagine it is really that big of a job unless they have to take half the car apart to get to it.

Please help...its really frustrating knowing my ABS system is not working.
