Speed signal HELP!!!!!

[zenn0ne]

So here's my situation, I'm running a fully built s52 for boost on a 91e30m3 and now I'm at at the last phase of my high power turbo build...I'm running a AEM stand alone and I would like to do boost by gear/mph....has anyone done this on their m3 or does anyone know which pin i can tap into for speed signal for the AEM......Any help would be greatly appreciated as this will also somewhat take care of my traction issues :blues:

speed signal is coming from the rear diff. Just trace the wiring?

[zenn0ne]

what would the pin number be on the c101 for the cruise control out put signal I'm not very good with wiring as you can tell
