M52 questions,breather, cooling fueling

[Kanee30]

Hello there recently bought an e30 with an m52b28 it's half finished and I have a few questions on what to do so to start!

The breather pipe that would normally go onto the air box what do people do with this? Mine is currently flapping in the wind! I've been told to fit it into the air intake elbow is that correct it currently has what I believe to be an air temperature sensor in there but where would this go?

Cooling I'm running a 2.8 rad with an electric fan mounted on a switch inside I'd like some direction to make this auto switching!

And fueling I have an m50 manifold and injectors fitted my ecu is mapped to the m50 manifold but occasionally I'm getting strong fuel smells in the cabin and any insight would be great

Thanks in advance Kane

Not sure what you mean by the breather that should go to airbox, but I make a loom to run a fan automatically from a sensor mounted in the rad, if you can smell fuel you will have a leak, ive seen so many bodges on fuel systems even by so called specialists its scary...

Fan: Just replicate the high speed auxiliary fan wiring here, intended as part of a air con installation.
Fuses and relay positions are already present in your fusebox, and just needs the 'stat and fan iooms added.
