RB20DET and RB25DET coilpacks are they the same? is the wire harness the same?

I was wondering, as i was about to pick up a set, they appeared to be the same form the pics, and i was thinking that since there is a good chance they are not that at worst i could scavenge the wire harness for a wast spark setup. what does everyone think? my coilpacks are all cracking out and giving me issues so it is time to upgrade.

RB20, rb26, and rb25 s1's have the same coil packs. Rb25 s2's and NEO's have ignitors on each coil, and will not work.
