Hi Everyone, I have purchased a Technic PNP harness 688HK for my 2022 540i and was trying to install my trunk sub a few days ago, but once I exposed my amp, I saw that the factory harness is way smaller than the one I got from PNP. I've emailed them about this issue, they asked for my VIN and never got back to me since. Can't even find their phone number to call. Very upset with their service. Did anyone successfully add a sub to their LCI G30?

I took a picture of my 20, definitely didn't seem to match the pictures i have seen. The technics has 2 rows of connectors, mine only had 1.

How would that work with so few wires? With HK you have 9 speakers so need 9 pairs of wires. Are you sure you’ve got the right connector?

Because of this I pulled mine apart (2020 pre-LCI) and there is a 20 pin connector. I thought the amp was on the right but it’s on the left and learn a lesson not to remove the rear seat side bolsters, what a pain to get back in.

Did you ever figure out which was the correct harness to get from Technic?

Yeah, just email them your VIN before purchasing.. they have no return policy, so better safe than sorry.
