hei4 wiring question

im using v3 board and going to try out a gm hei 4 pin module.
i currently have my ms wired for vb921 and am wondering what i need to change to make the hei work.

i want to run the signal out the db37 pin #36.

im pretty sure i want to run "top of r26" to ign and disconnect ign from igbtout. i have a few questions about this..

1. what resistors to use between them, if any.
2. wether or not i need the 5v pullup mentioned on the msns setup page. the setup page was for v2.2 board and using fidle output.
3. if i need a 5v pullup, where can i get it from on the board?
4. can i leave ign connected to igbtout in case i switch back to the vb921 later?

thanks

im mainly wondering what the difference is between using fidle and using "top of r26" for spark.

im pretty sure mobythevan used a 5v pullup for the hei 4pin.. and i think i recall reading the vb921 takes a 5v input signal.. seems like it would work how i explained it. can anyone confirm?
