How to install blower motor relays??

I don't know if this will help or not.
It might show you where to connect the relays.
The first part is a bit boring.

You may need only the 2 relays one for the high and medium because they don't have all the resistors like the low does, but it probably wouldn't hurt.

I did these diagrams . I think this is how it works. I'm not a wiring expert. If someone wants to correct them go right ahead. It would help the rest of us too.
