rb20 coilpacks to rb25 ignitor pack

[sil80turbo]

i have a coilpack setup like this...

made for an rb20 that i'm trying to install on a s1 rb25. the 2 plugs on the coilpack wiring are different from the rb25 plugs which have one less pin. so what pins need to be changed when wiring the rb25 plugs to this setup?

or how can i wire up an rb20 igniter pack???

i did this awhile back. i converted a 20 harness to work on a 25. I had to swap some pins around and change the connector ends. I just studied the pin outs in the FSM and it worked fine when i was done. Anyways check out these links for some help.
