That is not a “Technic” harness if you got it from eBay.
Ask your seller.

The bimmertech pp86dsp must have some internal modifications to be able to supply power via the harness like the oem amp. My understanding is the only difference between the pp86dsp and bimmertech pp86dsp, was that bimmertech provided a harness for plug n play.
I find this odd because I’ve read that the OEM harness only supplies 20amps. The pp86dsp requires more than this for power spikes, hence the requirement to directly get power from the battery.
I wouldn’t think any modification to pp86dsp that bimmertech made would resolve that issue. I did see that the pp86dsp is low amperage but requires 40-50amp fuse for brief spikes.
