Hello; I am installing the H-D contoured chrome and rubber heated grips part # 56100257 .

The instructions (which SUCK) show connections to 2 power sources.

1. to the B+ connector
2. to an accessory powered circuit.

Seems to me that connecting to the accessory circuit would all that's needed.

Help?????

 

Accessory circuit may only be the on/off for the with the battery connection providing the actual power for the grips.
