And they're off!
First one done! I think this fuel relay one was supposed to be on a relay. I'll figure it out soon enough.
Got a good chunk started. Also have a lot of questions.
Wire 27x on the expansion board harness goes to pin #7 on the monotronic side for the VVT. Still going through the question marks one by one.

Turned my attention to the grounds. I might take a different approach by making a separate grounding block that connects at the common chassis ground. I'm fearful that I might be overloading some pins by attaching more than one ground wire. Thoughts?
I still need to wire the coil drivers so there are 6 more grounds there.
On to the crank signal wires with the shielding. I cut an old cable wire from the ceiling of my basement and cut/pealed the shielding to re-wrap the signal wires after I soldered them.
Not too pretty but I'll wrap it in electrical tape to clean it up and secure it.
I need to get some 18 & 20 gauge wire and solder in my coils. Any input on how to ground all these wires would be great. Thanks for looking!

So happy I bought a full plug-and-play MS2 setup after seeing this.... Yikes.
I feel very overwhelmed at the moment but Snap and Derek (bimmerforums.com member) have been huge helps. It is the unknowns that I have with how the software works that concern me. I also feel like I need to put some resistors somewhere but I haven't looked into that yet.
Nah, just a lot of information checking. He will get it just fine

Uhhhhh khakis

Home depot sells shielded wire too.
Grounding everything to the same chassis ground is definitely a great idea. I would be less worried about overloading grounds and only slightly more concerned with any noise in the signals due to shared grounds. A handful of the ground pins are the same on the harness (multiple pins with continuity to eachother) so that even isnt much of a concern depending on which components are grounded together.
Any excessive electrical noise for a component will how up in a log file . Youre going to love the diagnostic capability of being able to see what all your sensors are doing

Even though they are common grounds, I would run all separates wires to a common point on the engine block for best results. Don't connect multiple grounds before the engine block.

Shouldn't I use the grounding point that the ECU uses?

Coils are all wired up. I need to see if I need to run them to grounds coming from the harness or if I can just run them directly to the chassis ground. I'm leaning towards running the grounds to the harness.
I disconnected the grounds from the MS3 and Expansion board from the pins. I'll run these to the chassis ground for sure. I don't want to overload those pins.
I still feel like I'm winging it so please help with any input.
A wired up coil.
