I just finished wiring my Lc1 into my truck. When I had it installed the calibration ground and heater ground were both ground to the chassis by the fusebox where it is powered. Now I took the system and analog ground and connected them to 14-guage wire and it comes out under my dash and will connect to the EIO. I did the same with my analog 2. Now my question, will 14 guage wire handle it, I guess I'm not worried about that being too small to handle the current, but will it be too large to fit in the EIO connections?
Also for a quick-connect type option, I used a 2 wire trailor-type connector so I will be able to just unplug it when I dont have my laptop or EIO in the truck with me.
