Removed cats now CEL
How much resistance do I need to give the ecu harness for the rear o2 sensors to keep the ecu happy?

A resistive load will only simulate the heater. The O2 signal steps above and below .5V every 3 seconds or so. You need to provide both to the ECU to avoid the CEL. That's why they sell simulators.
