I got as close as I could... '84 318 s50 swap wiring help plzzzz

[brainfood]

So this is where I've gotten myself to so far, can anyone help out some more and let me know how close I am, what should be changed or added?



Any help would be appreciated, I'm trying to finish up bay prep today (did a partial shave) and it would be nice to get some wiring done soon too.

C101 ____________<-> X20
#1 Blue_________ <-> #25 Blue________ = Alternator
#4 Violet/ Brown__<-> #12 Violet/ Brown = Coolant Temp
#7 Green/ Violet__<-> #13 Green/ Violet_ = Fuel Pump
#8 Black/ Yellow__<-> #18 Black/ Yellow = Starter
#10 Green________<-> #21 Green ______ = Power Supply w/ Ignition ON
#16 Brown/ Green_<-> #23 Brown/ White = Oil Pressure
#17 Blue/ White___<-> #19 White/ Green = Service Indicator Light

C104____________ <-> X20
Black____________<-> #20 Black ______ = Tach
Yellow ___________<-> #24 White/ Black = Fuel Consumption

Im not 100% on the C104 colors though. but that literally is what my car is running on right now. 84 318 car with a OBD1 E34 Harness, so the X20 might not be 100% similar. Also, you are pretty close! Keep it up. The 84 318 is an amazing car with a 24v, especially if yours has manual windows and locks like mine does. My car weighs 2450, but I have an aluminum block also, so you'll probably be right around 2500

Awesome, thank you so much! And I have electric windows and locks, but I was considering converting at least the windows at some point. I'm also pretty stripped out, should be fun! What trans/diff combo are you running?

I didnt bother stripping it out. Its my daily. Im using the G260 and 3.73 LSD rear end. I love it. I get 25-28mpg on the freeway depending on how much pedal Im using.

Subscribed. I'm curious as I will be doing the same in coming months.
