Many thanks to JC and Kaiser for the pics they sent last night! The alternator and starter wires were identified as well as the ABS unit power wire which is needed for a 24V swap. There is still a mystery 2 pin connector in the same loom as the O2 sensor connector which could possibly be for the reverse light switch? but it seems strange for that to be caught up in the engine harness instead of one of the chassis harnesses.
I stand a much better chance of getting the engine fired up without having to troubleshoot things now. I will take one last look at the remaining connections and see what I can make of them, install the harness on the engine and move on to the clutch and trans tomorrow.

What year is your chassis?

Even though we already spoke. This ones for the lurkers

1991
That explains why I've never dealt with the ABS wiring!

Looks good dude!
The small 1/8th wrap is quite annoying to split haha

Rear main seal installed. BMW brand with no garter spring. Black rtv on the gasket, 7 ft lb on the 6mm hardware, 16 ft lb on the 8mm hardware.
All of the appropriate brackets are installed (Roses are black violets are black, everything is black)Its a bit of a puzzle doing the OBD1 swap and not being familiar with 24V engines. I had some things bolted up on the wrong holes until i realized things werent lining up. There are 1 or 2 6mm holes on the elec. harness bracket that need to be opened up to 8mm
the front knock sensor needs to be angled slightly to clear the bracket and the rear portion of the bracket needs to be bent slightly to clear the original M52 lifting bracket
I will wait until the trans is on to put the wiring harness in place since i dont want it to be flopping around in the way while trying to stab the trans.

Looks quite good.
Don’t buy crappy ICV hoses. They crack and the blow up and you hunt for idle all over the place and then your gf is convinced she broke your car.
I bought slicone ones from maximum psi. Overpriced for what they are, but knowing they’ll never need to be replaced sure is nice

URO is usually junk, but also cheap. Expect one summer before crackage.
One summer may be optimistic.

One summer of driving would be amazing
I’d 2nd that!
I don’t think I have ever replaced my ICV hose probably the same one it came with. I did how ever have an issue with the fitting in the back of the intake popping out, falling off, or whatever decided to keep happening. I did however solve this issue with an epoxy called plastic bond.

Post irrelevant: I dont have a gf
The ICV hose i bought is “URO” brand which is probably junk, but i will keep an eye on it once im running
Seriously throw it away
The URO brand I had lasted maybe 1500 miles before it split in half

I used this
However there is no provision for the small vac line that runs from the valve cover PCV to that clip (as we know in stock config there is a nipple there for it)

Now that is cool, wish I would have known about this 5 years ago.
