a If 25V (2) and TH-R have wires connected, disconnect and splice together with solderless connector.
b If TH-R and TH-W are jumpered together, connect 25V (2) lead from S86 to TH-W on S8610U1003.
c Use Rajah to quick connector adapter (supplied) or cut Rajah connector off ignition cable at module end; attach insulated quick
connect for connection to S8610.
d Leave black jumper connected.
e Terminals may be marked 25V on some models and 24V on later models. These are functionally equivalent.
f On dual igniter and sensor models, remove jumper quick connect from S8610U1003 Sense terminal, cut jumper wire at circuit board,
and discard.
