So explain like I’m 5 what you mean by the fuse in parallel vs series, please. I have the same fuse pigtails and have used these before so I have some for this job. You tapped the heated steering wheel fuse?Here is mine setup. Main concern was high current for steering wheel heater and dash cam battery pack which charges at 9A and came with 20A fuse (20A + 20A). Because of the shape of fuse box I couldn't push the tap all the way down. Cannot say the connection was loose or flimsy, but just not full enough - which bothered me for some time. Finally I took the panels off and checked connections when both were at full power - temperature didn't go above 47C (ambient was ~17C). Considering I will use steering wheel heater mostly in winter - that should be good. Keep in mind that fuse tap orientation matters - fuses should be connected in parallel and not in series which could burn the bottom fuse in the fuse tap.
