@blwnaway, the aftermarket connector is getting hot, the connector is deforming from the heat. also the splice connections that I made were getting corrosion (copper wire turning green). They failed after a few years.

I think the heat is coming from the wire gauge being smaller and I think the spliced connections were not sealed well enough. thats my best guess.

I had to redo the sliced connections and replace one side of the connector (had an extra on hand).

I'm planning to replace that connector with one that matches the wire gauge and use sealed splice connectors.

I was hoping to use the original connector (stock bmw) but I can't find that part new.

 

Yes, sounds as if either that connector is not rated for that sized wire, or the pins weren't getting full contact in there.
If you can't find an OEM connector, try and find a connector rated for at least 12ga, better yet 10ga.

While I'm not up on how the 2 wire system is set up as far as the resistor for low speed, I know the 3 wire system generates a good amount of heat in the wiring for the low speed because of the resistor. That's one of the reasons I decided to simply bypass the resistor and not worry about low speed on my car, instead of doing the resistor mod. Doesn't bother me if the fan is a little louder in what would normally be low speed conditions.

If you have to, you might need to raid a salvage yard for an OEM.

 

@ssoliman found this:



I do know that standard Weatherpack connectors are rated for 14 ga at the most, may simply be the issue.

 

I like the idea of bypassing the resistor all together. Simpler is ALWAYS better

that one looks good also. however its two pin. I need three pin.

I have ordered some three pin connectors. now i wait.

i'll update once i have it "fixed".

THE question remains. ***Why is this connector not available from BMW / MINI?***

 

Oops, just in case:

 

thank you sir, i will check it out

 

fixed this over the weekend. ill post a pic. excuse the extra electric tape. had my son helping me and he went a little extra

ended up using this connector:
and these for splices:

 

The wires were 14 gauge
