@grantwest would you still have the drawing of the 8pin → 12pin instrument cluster adapter for a T1 to T2 upgrade? I’ve learned the long way(finding a problem, eliminating things, looking at drawings, etc ) and then found this thread after @AssyRequired pointed it out. Now that I have the Motor Thermal Switch hotwired, I’m looking to get the display functional again and some of the drawings and links in this old thread don’t work or show. Thanks. ---
