DIY'ers,

I have a quick question.

Relevant details of what I have preparing to go into my 2, are below to "fix the glitch" of BMW's lackluster "HiFi" sound.

Detail's:

Car: 2017 M240i 8AT RWD "hi-fry" 676 optioned coupe.

5 year old Technic 7ch HiFi (676)/HK(674) harness. - https://technicpnp.com/product/7ch-h...hk674-harness/

F & R coaxials - https://audison.com/product/apx-4/

Amp for F - R - Underseat Stock 8" <sarc "Subs"> - https://www.jlaudio.com/collections/...plifiers-98605

Trunk Sub - https://www.jlaudio.com/collections/...-systems-93324

Amp for Trunk 10" JL box - https://www.audiocontrol.com/car-aud...iers/acm-1300/



Here's to hoping this is a straight up YES/NO kinda question.


The search function finally used it's "safe word" and called it quits with all I have been using it, so now I turn to ya'll, respectfully, for a resolution.


But my question is, would a 5 year old but perfectly serviceable Technic 7ch HiFi (676)/HK(674) harness, work with the 2017 factory audio harness in my 2 or did pin-outs change, etc. and I need to go get a new one?


Many thanks to all of the awesome people here that freely share their knowledge, and I thank you for it, so here's to me being sure someone will know.


Thank's go out to Viffermike - https://www.2addicts.com/forums/show...r+installation and Zooks527 - https://www.2addicts.com/forums/show....php?t=1202389 for their fantastic instructions on the how to install it thread's.


Thank you for making another DIYer installer's life a little bit easier by your efforts.

Is a 5 year old part going to work in a 6 year old car? Why wouldn't it?

If you have doubts with your setup, start with one thing at a time. Test. Move on to the next thing.

Fair point, I just am one of those paralysis by analysis types. In retrospect your reply clicked the, "nobody has made any mention of the harness not working across the HiFi amp range across so many year's and platforms.
That is a solid answer in of itself. So thank you very much for taking some time to answer my post!

Will proceed with testing and get this gear back in action again.
