I'm working on an '82 R65 that has the larger upgraded ignition control unit as shown in the diagram below: It was zip-tied to the frame with a chunk of rubber between it and the frame. So, I bought the correct mounting bracket as shown but can't figure out where it mounts to. There are two places with screw holes with the same center-to-center measurement, but neither positions it so that the plug doesn't interfere with the frame or main harness. Has anyone run into this before? Where does the bracket mount? Do I need to drill holes in a frame tube to mount it? Any help would be greatly appreciated!
