Nicolasm6 Posted May 16, 2023 Report Share Posted May 16, 2023 hello. If anyone can help out I would really appreciate it. Is there any connector I need for what i have the two red arrows pointed too. I’m swapping a k24 into an s13 and this is the Link G4X Hc20X plug in ecu.

koracing Posted May 16, 2023 Report Share Posted May 16, 2023 Those are expansion connections for additional inputs and outputs. If you need something beyond the factory header pinout as far as sensors or additional output controls - then yes you would want to get one or two of the XSL expansion looms to plug into those 8 pin connections. Typical uses: Wideband Analog input (Better to use a wideband input on one of the 4 pin CAN connectors) Fuel pressure sensor input Oil pressure sensor input Oil temperature sensor input Flex fuel sensor input Boost control solenoid output Etc.
