I’m very much looking forward to seeing any sort of footage you end up putting together. I’ve been too scared to pull the trigger on buying it until I know for sure that I can install the damn thing lol
For anyone else out there like myself who are trying to fix this in 2019, the part number referenced in "solution2.pdf" "KA7808" is obsolete. The functional equivalent is now UA7808CKCS.
