Ignition Cable difference (MR2 Vs ST205)

So my igniter cable got jammed in the distributor housing because of mild corrosion. When pulling it out, the ignition cable pin broke so I'm looking at a replacement cable.
 
I've noticed that the MR2 and the ST205 (Both Gen III 3SGTE's) have what I would have thought the same cable, but wildly different prices:
 
19590-74170 – (MR2) $14.8
19590-74220 – (ST205) $41
 
Can someone confirm that I should be able to use the MR2 lead? Keep in mind I have a ST205 Engine swap with a ST205 igniter in my MR2.
