HSTuners - View Single Post - ECU Wiring Modification - 90 civic to 90-93 integra

Well I've done a lot of googling, and after a long search, i've come up with this. Are these the only ECU wiring changes when going from a d16a6 in a 1990 civic si TO a 90-91 integra b18a1?

A10: Pressure regulator cut-off solenoid valve (add this to Si harness)

B2: Dashpot Valve (remove? tegs dont have this)

B5: Alternator (remove? different position, but only one for teg. wtf?)

B19: P/S oil pressure switch (apparently remove the electronic load detector for the Si)

C10: Brake switch (add this to Si harness)

I got all this from:
http://b16a.honda-perf.org/wiringb16.htm

What bothers me is i've HEARD there are only like two wires that change. And since I don't have an integra wire harness, I've got to mod the Si one.

Has anyone done this specific conversion? Or anyone know of a good resource online that I could check out?

thanks
