My ecu gave me a code 21. Where do I locate the Ignition Signal circuit? :Werd

Hey everyone,

I still have yet to get my car started. I still have a problem with the security going off like Bon Qui Qui at King Burger. I unplugged the Head light circuit under the steering wheel as to avoid the battery drain. Now I am trying o start it but it won't turn over. I pulled the codes from the ecu and it gave me a 21 this time. I think my ecu was a magic 8ball in its past life I almost want to shake it and see what it give me next. With that all said could some- one tell me where the ISC is? I can't find it in the manual. I checked the index and the EL pdf pages.

Thanks
