Ah ha here you are the E1-01 connector whilst maybe only be showing with 1 wire in use is actually as below;

it has 5 receptacles on the lower and three on the upper - but obviously not always all connected ....
Trouble is yours shows 6 connectors on only a single row......
However some of the colours match up ..... R/W Red/White, R Red & G/R Green/Red
Doh ......
I guess the connector can't be seen when the wheel is in place ? But I'll have a look at ours tomorrow ... but I'm not taking the wheel off

No way
