2005-2012, #10469
2013-current, #85683
****************
The original is for all SSP models up to and including 2004 (the last year SSPs were made).
The 2005-2012 fits 2nd and 3rd Gen (everything is the same as #10401, EXCEPT the wires are longer to accommodate the different frame and wire routing/starter button location)
2013-current is intended for 4th Gen Performers with the electronic (battery) igniter button. Everything is the same as #10469 EXCEPT for one wire terminal difference.
****************
Piezo "clicker" buttons have a 1/8" male terminal for the white negative (-) and a small post terminal for black positive (+); the battery-operated buttons have two 1/8" male terminals for both neg and pos.
Any of the 3 burner "kits" can be made to work with any Performer, any year, subsequent to the proper wire terminals/starter buttons modifications etc. being performed.
****************
Note: You can also loosen the bracket from the burner tube and install the wiring on the other side of the bracket, effectively "shortening" the burner tube for better firing beneath a Slow 'n Sear and/or helping protect the wiring from heat damage at the bowl.
Note: A new burner tube assembly might come preassembled with the ground wire on the "wrong side" of the bracket or too close to the bowl when installed. Unscrew it and fix as needed!
