E30 318I M50 Swap Wiring connector missing!?

Alright, I know I sound like a noob here.

But here goes. I hear people talking about making adapters for the wiring from M50 to E30 with the round connector such as this.

My 1984 318I does not have this connector. I've taken apart the dash, looked in the engine bay, under the car, in the dash, EVERYWHERE. It is not there.

The only connect that I could see would be a square connector with roughly 6-8 pins in it.

Is this normal because it's so old?

Does anyone have the wiring schematic that I need for this?

I'm REALLY close to getting this swap done, about the only thing stopping me is the wiring and a fuel cell/pump.

Your car isn't late enough to have a C101, that square connector is what you have to work with. I could help you, but Graham (Dissesembler sp?) put a 24v in his early model car. Message him if you get stuck, he's a good guy I'm sure he would be willing to help.

No I am not screwed, I just have to do my research and make it work.

Don't be a prick.

Yeahhh you can, it's just a bit more work. And you actually have to run a couple wires.

Early cars have a rectangular shaped, 19pin C101 connector. It is tucked between the shock tower and driver side fender, underneath a plastic cover. You also need to run wires from the 3 pin C104 connector above your glovebox to your adapter as well.

Check these links for info

Does it matter that this is an E36 harness with Vanos?

Thanks for all the info so far, really appreciate it.

lol, yours is almost as dusty as mine is (the dust is stuck on there pretty good, a couple hwy blasts couldn't even knock it off). Looks good

We also did the same thing with our air filters. I tried to get the E36 box to work for that OEM look, but there was no way it could fit without major mods. I don't know how the one guy on r3v got it in there.

1 gripe though: ///M badge fail

^ Why not hack off the bit on the e36 airbox where the MAF clips on, and glue it along with the funnel into the E30 airbox? That would look nice and look fairly oem.

Haha I know, I didn't put it on there I promise!

Previous owner put that badge on, I'm more then likely not putting any plastics on the engine, painting the valve cover creme color with german flag colors incorporated.

See how it turns out.
What did you guys do about your Auxiliary thermostat?

I really liked how the E36 box looked in the engine bay, so I cut off the bracket that held the E30 airbox in.



It wouldn't be a big deal to remake it, but at this point its just easier to put the filter in by the brake duct and route the plumbing nice and neat.

There are some pics of valve covers done in similar fashions in the r3v "24v engine bay thread" I think it looks awesome. Was thinking of doing just the raised ribs myself (OBD II, plastic valve cover), your going to paint the whole valve cover?

I blocked off the ports for my TB heater. Car won't see winter.

Edit: Just realized you said you weren't putting the covers on lol
