Wire Diagram | SR20 Forum Is the wiring the same on and s14 ka24de vs. s14 sr20de? Everything seems pretty cut and dry. I have heard that there is one extra wire on the sr20 but can't remember which one. Does anyone have the sr20de wire diagram? Swapping motors in my 510 and found a diagram that shows the ka24 swap. Any help would be appreciated. PLMS Developments - SR20 Setup Tips ECU must be seeing "TPS Closed". This is a flag which is set inside the ECU when the throttle is closed. Some engines use a switch on the TPS to provide this - SR20 ECU's simply look for a certain voltage on the TPS (Throttle Position Sensor). Refer to TPS Adjustment section. The ECU will only access the idle tables when the TPS Closed flag is set.
