Wiring aem s2 on rb25det, help!

[redrbz]

Before I start splicing wires and connecting new pins into my rb25 s1 ecu harness, is this the correct way to wire up the map and iat? I got this from aem website. Oh, and also does the aem disc need to be install first in order for it to start property?

looks right...
and yes, if you want it to actually start you'll need to install the aem disc.

You need to add the pins to the ecu harness too. Also copy some of the stuff from the RB26 calibration file. The Rb25DET file is incomplete, as far as I remember the tach stuff isn't copied over so it won't work at all till your done.

Yes, I see that on my rb25 ecu plug, they don't have any pin for 35 and 36. So I made my own pin and connect the wire to the map and iac harness. On pin 34 I don't get it where they say switch 2, when that slot doesn't have any pin into it. I was just wondering can I just ground?

I didn't even hook that up. I just did the map sensor and IAT. I already had a different wideband (Zextronics).
