The molded hose section provides some sort of protection, I guess?

Turbulence in the fan box may make the stranded copper conductor wires move around when the fan is on as well as vehicle motion. Flexing wires break, eventually. While newer, it may not be as well made, so, you may want to give the new fan a break and maybe use some adhesive.

Or send it back and get a Siemens motor that iPd USA used to sell. MTC which is maybe the same as your Four Seasons brand motor.

Or Siemens VDO, made in China, says the FCP Euro copy:

Does not show the port the hose secures to to protect the wires.

I'd guess it'd be okay to solder wire lengths and shrink wrap these. Solderless splice connectors can abrade the adjacent wire insulation. Sort of like sealing up under hood wire connections to survive under hood connections. If you do go solder-less connectors, use some with dielectric compound in the bonded interface so corrosion won't form at6 the splice. Offset the connections (1 higher, 1 lower) so they do not bind in the hose during install and operation (vibration and heat and cold).

Off set the splice for each wire so they do not bind

Else it should fit.

Have you tested the motor? Our Art has some web pages on the issue.

1990 240, tho motor swap yet more like your 1993 with Made in Canada VDO motor.

Looks the same as the Made in China Siemens/VDO motor.
