I recently purchased a "kit" for my Grip Rite Compressor Model GR90G10 to convert from a cable style Throttle Control to a Pnuematic throttle control. My order number is 585995. It came with no instructions and I'm not sure how or where to install the part #192EGX240QA Throttle Control. Can you please help me out. Seems I'm missing something. It doesn't have a linkage to hook to the carb throttle. It's just a fitting.
