I can't seem to find this info no matter where I search. Maybe I should be wearing a dunce cap, but is there a video or clearer pictorial of installing the PNP adapters? The JB4 manual info seems vague. My JB4 is in and functioning fine. Also, do I need these adapters if I'm going to use E85? Are there any other items needed to run E85?

I believe the adapters will be required if you want to mess with more accurate fuel mixtures with E85. The install is pretty easy, just follow the fuel wire install but instead of piercing factory wires you would do so on the adapters. The wire you tap into on the adapters is colored red I think while the rest are black. It's been over a year since I have installed mine. If you want to run anything above map 1 it's important you have gapped the spark plugs also. There are a few threads on which gap is used.
The PNP fuel adapters will not let you run straight E85. You need the flex fuel kit for that. The PNP adapters simply let the Jb4 more accurately measure your AFR and adjust accordingly. For the stinger 3.3 you attach the cables from the JB4 to the red wires in the adapters with the supplied taps and insert the adapters in line between the driver and passenger primary O2 sensors.
I have a lot to learn. From interior to exterior to high performance - everything you need for your Stinger awaits you...

Yeah, if you are ever unsure about something then just ask here. I enjoy trying to help and I'm sure a lot of people do. I don't think the car can run fully Flex Fuel with the current fuel injectors. I think the most you can get is maybe a E50 mix with the new BMS CPI kit. That is definitely at the higher end of mods while staying mostly stock. Most people stick with E30 mix which is depending on fuel you have access to is 93 octane with 4-5 gallons of E85 to mix.
