We don't have notes on when we started orienting them in the current proper configuration but we think it was around 2010. Now, the female connectors of each pair must be on 22 and 23 or you will get a wastegate fault. Previously DB25 positions 10 and 22, and 11 and 23 were interchangeable. The G5 plugs in to the same JB4 harness, although those using older harnesses may need to swap around wires on the DB25. JB3->JB4 Harness Upgrade Directions & JB4 PinOut wiring locations: Plug the SLD (Green) male end into the gray connector on the male side Plug the SLD (Green) female end into gray connector position #17 on the female side. Remove this wire completely by releasing it from both female & male ends of the gray sub-connector. Now button up the DB9 cover with the new wires.įind #17 on the FEMALE side of the gray sub-connector. Insert small pins from the wire set into DB9 positions: The SLD wires being added are generally green color. Remove DB9 cover - Note that only 3 pins are in the BMS USB Cable normally. PART 2: ADDING SLD WIRES FROM BMS USB CABLE TO HARNESSĢa. I didn’t need one, don’t know how to use one, but here’s a link: Good Luck! The pins can be removed from the DB25 using a D-Sub Pin Extraction Tool. If the 23 wire (purple) goes to goes to the MALE side of the white sub-connector, it MUST BE SWAPPED with the like colored 11 wire (purple) that it is paired with. If the 22 wire (green) goes to the MALE side of the white sub-connector, it MUST BE SWAPPED with the like colored 10 wire (green) that it is paired with. Do a continuity check w/ multi-meter to confirm.
1 (green & purple respectively on my harness) MUST go to the FEMALE white sub-connector. JB4 harnesses older than 2010 may need to have the green or purple wires swapped.ĭB25 Wires 22 & 23 Fig.
