Well here is my problem, ive got the msII processor v3 board and im trying to do the 420a board mods, but my problem is i dont know what directions to follow, ive seen two sets of directions that show different ways to wire it up. One set of directions dont even list using the extra VB921. Well this is one set of directions that ive found http://www.msextra.com/ms2extra/MS2-Extra_Neon.htm#Neonsoft
and these are another set of directions ive found http://megasquirt.sourceforge.net/extra/setup-neon.html

Are either of these correct, and what configuration is best for eliminating noise out of the signal, ive heard using the VR circuit with some adjustment, and a few other things to try, i dont know whats tried and tru or what, im looking for someone with experience in this to help me out. Thanks in advance and if there are any more questions please feel free to ask, and if your wondering about the setup i have a thread about the engine ive built, but for some reason i cant find it on the site, u can find it on google by searching for 2gnt and my user name (EclipseGSRT-4) and clicking the cached link. Well thanks for anyones input in advance...
