I cannot find any wiring schematics on how to wire my wide band into the EGR to my 03 blue/green PCM. I keep reading how people do this but I haven't seen any detailed schematics. I really need to know this as I have only HPT basic. Any help would greatly appreciated.

Thanks for the link. I have read this seveal times but still there is no schematic on what to connect from the wide band to the PCM. The egr sensor circuit would be the logical wire but what wire on the MTX-L do I connect to that? Also since I have no downstream O2 sensors in the Chevelle, could I use one of the downstream circuits to monitor the wideband?

Yellow is the wideband output, per page 12. Brown is the narrow band output.

I have the same wideband. Great product.
