Tapper and RB Tapper have the same harness. They are few and far between. I am deconverting 2 Tappers currently. I am using 2 Spyhunter harness. The AC section for Tapper and SH are identical. The DC section is close. There some differences mainly the cheap squeek wiring has to be eliminated. Also the control panel wiring has to be altered. Everything else is the same. Closest match I have been able to find. Good luck on your hunt.
