Do you mean that you "replaced" your engine wiring harness??
If you re-wired it yourself. . (big job!!!!), then my question is why did you DIY?
In any event, follow the procedure that detailed in MENU#24 on my web pages. Your ETA may be going bad as the root cause of the ASR light.
Dump the codes in the ECUs indicated and see what DTCs are stored.
