Sorry about my english but I need connect PLX SM-AFR.

I read PLX WB Wiring Instruction on hondata.com and I've question.. Where I should connect 3,3V output from analog outputs in sensor module ??

I'll use plug from stock sensor. Should I put 1K resistor between A6 and A25 or just disable O2 heater in S-Manager ??

ok i looked at my notes again the gnd is to be pined under the 3.3v if you want to read in lambda instead of A/F values. i like my A/F numbers so you leave it unhooked. the box is grounded already with the power and ground connector also the RX TX connectors ground the device.

they gave me 1 wire with a connector on it i used for the Narrow band (NB) i cliped it into the harness for the plx then took a connector off a dead 02 and soldered it to the white wire. i de pinned the green wire and ran a 1k resistor between the 2 black wires. now i crimped a connector provided from plx to a wire and pinned it wo the wide band (WB) spot on the plx connector and then soldered it to D10 of my harness.
