Only video/channel that went into the E9X/E8X wiring enough for me to fix my 135i's wiring.

[@anthonydelatore9477]

I fr cannot thank you enough for this video. I been chasing electrical issues with my 135s fan for months (2EFE code) The previous owners tried to wire in a second fan plug and bypass the battery distribution box to fix the problem. I ended up having to remove all of extra/unnecessary wiring for the second fan plug, buy a battery distribution box, replace the relay for fan, and repin the DME/CAS. Previous owner should have just spent the $60 for a new battery distribution box, and a fan relay lmao

Dude How can i get the full wiring diagram & the insta bmw ?

[@alexlongpre4527]

SW stands for Swartz --> black BL stands for Blau --> blue RT is Rot --> red

[@deandefrancesch613]

Frank. That was a legit explanation of wiring diagrams. Great job at explaining it even though it was some really technical data. What are you using to get such in-depth diagrams for the bmw?

[@Garageaholic]

Thank you Dean! Those WDS diagrams are on eBay really, a CD Has all that stuff like INPA, EDIABAS, WDS, TIS, and NCSExpert. I believe even some sellers provide a means for virtual desktop , which is mandatory nowadays as these applications operate only on Win XP.

[@dasfahrer8187]

What do the additional alphanumeric and symbol combos above the wire gauge mean (e.g., 31L, 30

[@Garageaholic]

Actually not sure on the actual conversion. The numbers are the terminals and you can look that up. I’m guessing the letters are an abbreviation of the German conversion of language.

[@josetorres-op6po]

can you make a video of testing the radiator fan manually.

[@Garageaholic]

like with a function generator and oscilloscpe?

[@jonsanchezperformance]

Trying to make a harness for my N54 to wire up to maxxecu stand alone, wiring is not my thing and wait times for a customer have been over a 6 months. How would you go about this?

[@Garageaholic]

Make wiring your thing…. There’s tons of resources out there to help!

[@jonsanchezperformance]

@@Garageaholic where do you recommend I start? I successfully dct swapped my E90 already and after making some good power on my N54 I decided to dump msd81. Looking for some consistency.

[@jonsanchezperformance]
