This power cable (suitable for all Macna, except the Foton gloves, and KLAN heated products) forms the connection to a DIN accessory plug as found on many BMWs.
If you are looking for the 'normal' cigarette lighter connection, then look here.
Make sure the fuse in your power plug has a minimum current rating of 5A, as a heated garment uses between 3 and 4 amps of current on average. If you want to connect several pieces of clothing, a current of 15A is recommended.
Macna and KLAN make heated motorcycle clothing and lets you choose how to connect it. It requires a bit of puzzling, but the result is a tailor-made composition, depending on what you want.
In this case you chose to connect to the DIN accessory plug on your motorcycle. The power cable ends in a connector after 120 cm, where you connect the next power cable to effectively connect to the heated clothing.
For gloves and socks, use a dual connection cable.
Attention! A complete set of heated clothing (jacket, pants, gloves and socks) requires a 15A fuse (instead of the more common 10A) so check if the fuse between motorbike battery and plug needs to be replaced.
