As we all know, a SBEC2 is very different than an SBEC and you cannot simple plug it in. I have found and tested a solution simply place a jumper between pin#8 and pin #57 either in your harness or on the back of the SBEC2. Ma Mopar moved the ASD sense line from pin#8 on the SBEC to pin#57 of the SBEC2. I check my bare PCB boards to ensure both boards are happy with the change and we are good
My FWD stage 4 worked great (SBEC2-652) next to try my 92 SBEC2-377..The numbers after the SBEC2 identify the last three digits of the PCB part number.
