2020 bone stock supra except for brake pads. No real access to tuner near me so went with the JB4 with the Bluetooth option. Had one on a 2016 Golf with good results. Bought the flex fuel kit as well. Install instructions seem to indicate that for the JB4 to see the ethanol percentage I need to install the 0-5v wire. Is that correct? If yes, how the heck to I do that. JB4 is installed on drivers side with cable through firewall to OBD connector. Sensor is in fuel line, also near drivers side. Hot wire goes to red connector on the passenger side and chassis ground is also there. The 0-5v pin wire also comes out of the harness at the hotwire side (passenger). Pin goes into the 14 slot on the JB4 on the drivers side. Thatās a distance of about 4 feet with a wire that is, at best, a foot long, maybe 2.5 if I strip it out of the harness (donāt want to do that, harness is woven) Any one else run into this issue and, if so, how did you solve it?
