IV'E PUT ANOTHER B 18 IN MY CAR AND I'M USING THE SAME HARNESS FROM BEFORE. I HAD NO PROBLEMS WITH THIS HARNESS FROM THE LAST 2 B SERIES SWAPS, BUT THIS TIME I CUT OFF ALL THE EXTRA AUTOMATIC CONNECTORS THAT WHERE HANGING THAT WHERE NEVER USED BECAUSE OF THE M/T AND NOW I THROW A PRIMARY HEATER CODE FOR 02 AND A 2, CAN ANYONE TELL ME WHERE I expletiveED IT UP.

 

i would start by checkin the wires and the connectors..maybe u switched them around or the wires are worn out somewhere

 

IM GOING THROUGH EVERYTHING OVER AND OVER BUT I CAN'T SEE WHAT I DID WRONG. IS THERE MAYBE A LOOP THAT WAS BETWEEN ONE OF THE A/T CONNECTORS THAT TIE IN TO THE PRIMARY HEATER FOR THE 02, AND WHAT IS A(2) CODE? I SWEAR IT FLASHES TWICE IN LONG STAGES.

 

not familiar with the A 2, but you may have clipped the wrong plug, there is a plug that looks like the 02 plug but isnt... get your dmm out and start tracing those wires you clipped back to the o2 pins on the ecu, its really simple.
