I need to get the tach working properly in my MA61 with 7M-GTE (even though I can't stand the digital dash), and have found 'some' info on the MSD Tach Adaptor, but need further clarification on which one I actually need ?
I believe that it should be the '8920' version (the more expensive of course )
Anyone with any experience ??
Also the speedo reading is way out (not the main drama), but it is intermittent, i.e. it often does nothing. Has anyone had a similar problem and where would the first place be to look ? I'm going to try and grab another dash to try if it is something at that end, or may be the pickup ?
