Hey guys, does anyone know how to hook up the VSS to the AEM computer without the use of the stock gauge cluster? I have a rb26dett with a r34 rb25 rwd trans. (pull clutch). Following the wiring diagrams the 2 wires go from the VSS to the cluster, the cluster computes and then 1 wire goes to the ecu.

Ok, got it. Ground Gray/Red and hook up pin 53 on the ecu to the yellow/red wire (or vise versa as it does not matter.) and then you need to edit the calibration to read the right speed. In AEMTuner, go to sensors, then right click in the white area and go to Show options full list display, then scroll to VSS calibration. I am using 110 currently and its pretty close, but i need to fine tune it later.
