Any alternative ways for wiring a sec. 02 on a non obd ecu?
I have been informed that I would need a single wire sec. 02 for the pr3 ecu but I was wondering if I could rewire other 4 wire 02s to work so I dont get a CEL? Also do i need a sec. 02 to pass emissions only? I need to know asap. Thanks

You can chip the ECU to read a single 4-wire O2.
Otherwise you need to run two non-heated (2-wire) O2's. They should tap into the header primary collectors i.e. the "2" part of a 4-2-1.
