Hellen72c will have a WBO module.
In order to simplify the LSU sensor wiring, we used a board-to-wire connector on the board:

This is a XH series connector (XH-8A) with 2.50mm pitch and 3A current rated pins. We use double pins for the heater output and ground.
The best part is that JLCPCB has this connector in stock; actually, they have even two options: C146110 (white) and C37940 (black), over 10k+ total in stock.

Of course, this is a wide-known connector type with lots of mating female connectors with wires on ebay and aliexpress:

Some of the sellers write "2.54mm" pitch, but that's not correct, it's actually 2.50 (anyway, all XH series have the same pitch). One should look for 24AWG or less wires, not 26AWG.
There are also versions with long wires (up to 30 cm):

Or versions with raw contacts for manual crimping:

Most go with both male and female connectors, though.
