Hello Kit,
I think I found the connector you told me today (see attached photo, itīs the single red cable in the middle).
The connector looks like 4 pin but has only 3 pins.
Upper left :+12V unswitched, fused 10A (fuse 18 "Option")
Upper right : empty
Lower left : ground
Lower right : +12V switched
Iīve changed the fuse to 15A for can use the socket with or without ignition with 10A.
Do you know if itīs possible to order the genuine connector incl. the contacts from the Mitsubishi dealer ?
Best regards from Phuket
Alex
