This is what i followed for install it says nothing about what wire to connect to (pin 4 02 wire ).. Also i was reading not to connect (white wire) to pin 24 it can blow the ground track ??
Narrowband simulation install (DB gauge, Logging, ECMlink v3 setup) [LC-1 sensor placed in front o2 spot]
Red wire – 12v accessory power source (e.g. cigarette lighter or radio)
Blue wire – chassis ground
White wire - ECU sensor ground (pin 24)
Brown – ECU pin 15 (ECU Pinout - http://www.dsmlink.com/images/forums/1GECUPinout.pdf
Yellow – DB gauge’s white wire
(*Must reprogram Analog Out 1 values to match Analog Out 2 values using LM Config 3.15. Screenshots and software - innovatelc1orlm1install [ECMTuning - wiki])
Black – Calibration push button to monitoring LED to ground
*Note – The brown and yellow wires can be swapped in this scenario.
Narrowband simulation is then done inside the v3 software - v3narrowbandsim [ECMTuning - wiki]
