Thank you for viewing this item. PROVA Throttle Controller (Drive-by-Wire Controller) Subaru Legacy BL5 BP5 5MT Adjustable control position. I used this on my Legacy BP5 (early model). The power wire has a 20A fuse, so you can install it simply by replacing the fuse. It worked perfectly, and I am selling it because I changed the specifications. It probably works on BL5 as well, but please use it at your own risk. This is a used item, so please understand that it is non-refundable, non-returnable, and non-exchangeable (3N). I used it on a Legacy (early model) Spec B 5MT. I personally think it can be installed regardless of the grade, but I cannot be held responsible if it does not fit after purchase.
