Help !!! M44 unknown lines

I bought my E36 about a year ago and I originally bought it without heat . And with the cold season coming up I’m trying to figure out what connects to these ??? I bet it’s missing quite a few parts :( https://uploads.tapatalk-cdn.com/20181103/3d385c29a1145e20e54e6efb05806508.jpg

So whomever you bought the car from had a leaking coolant flange, the 3 outlets from the firewall. So they just bypassed the heating system/core all together. First you need a new flange.

Then it's a matter of reconnecting, checking for leaks and adding coolant.

Realoem has just about every diagram a BMW person needs. You should also replace the rubber o-rings.
