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

Check our intake install guide for a photo of the connector.

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.

For the C43 the injectors are more than enough to blend E85. It's your fuel pump that won't be able to keep up. I have blending E85 with 91 octane (California) for almost a year with no issues. I accidentally found the limit before going into limp mode. With my Eurocharged Tune 4.5gal is the max. I accidentally put in 4.7gal and the check engine light came on. Put more regular gas in and it went away.

Up to 30% E85 has proven to be fine for the platform, but unleaded race gas is great too if you have the cash for it.
