errorLOAD_CURRENTSL8-A-19SL8-A-19 "Auxiliary output 10" is rated 5.0 A but the load on this net draws 14 A (TB-J-M- Throttle motor −).
warnDBW_MOTOR_ISOLATIONSL8-A-34SL8-A-34 "Aux 9–10 14V supply" is fed from the same net as the ECU main supply (SL8-B-1). Link's S2000 DBW wiring feeds the throttle-motor supply through a separate isolation relay switched by the ECU, so motor power can be cut on a throttle fault. Add one, or confirm SL8 cuts the H-bridge internally.
warnDBW_SHARED_5VS2K-A-20 + S2K-A-21 + S2K-E-5 + SL8-B-2 + SP-5V-1 + TB-J-VCCThese 5 V supplies are separate in the stock car (S2K-A-20 [s2k_vcc2], S2K-A-21 [s2k_vcc1], S2K-E-5 [s2k_vcc3]) and here share one ECU 5 V (SL8-B-2). On a drive-by-wire car the OEM splits them so one short or fault can't corrupt both throttle/pedal tracks at once. SL8 has 1 5 V sensor supply pin(s). All are in use, so decide: accept the shared supply (and rely on the ECU's DBW fault checks), or add a separate regulated 5 V for the sub tracks.

Notes

Not buildable as wired: the S2000 throttle motor draws ≥ ~14 A at stall (FSM ≤ ~1.0 Ω) and every H-bridge on this ECU is rated 5 A. Use the cable-conversion variant, an Emtron KV (Aux 13–16, 15 A), or an external DBW driver.
