jb4 green wire

I’m trying to connect the green wire for my jb4 but couldn’t find any guides online, so does anyone know how to install the green wire on the c43/c450 models

Under the driver side airbox by the fuel rail you’ll see the wire only one will fit the connector so you’ll know

thank u i successfully connected the green wire I was also wondering if it’s safe to run 100octane race gas on map 5. If not what mix should I use in order to run map 5. I’m currently hesitant on mixing e85 cause I heard stories where it can be bad for the oem injectors, so I lean toward adding 100 octane fuel instead.

Put more regular gas in and it went away.
