The 11hp has two wires one with a diode to convert it to dc.
I have the complete wiring loom for the 15.5hp but just wanted to do a motor swap.
The dixon wiring loom already has the power set up for the blade engagement but will need some wiring done to get 12v to the fuel solenoid or just throw away the solenoid because they give problems. The headlights are also already wired up.
If i use the new wiring loom it will have power for the solenoid but no wiring for the headlights or the blade engagement.
The 15.5 wiring has a black wire going to a bolt in the centre of a black box. Another black wire connected to a yellow wire on the black box. There is also a red wire coming out of the black box. There is also another black wire coming out of the motor that joins an orange wire. All the black wires come from underneath the flywheel
