    Locations of ground points on Previa

    Hey all,
    Does anyone have a diagram or photos of the physical locations of the grounds as opposed to just the electrical locations in the schematic?

    I've mentioned I have an issue with my ISC not getting the voltage signal from the computer to the RSO pin. I'm wondering if it's a bad ground issue due to the voltage reading I'm getting for only a second initially which is lower than I'm guessing it should be after troubleshooting it.

    I just found the one from the engine block to the coil, then to the frame and I'm thinking I should go thru all of them and clean 'em.
