pin 4 and pin 5 is ground
Respect your thinking on that, but how im testing it is basicley in a closed loop, going nowhere near the battery. Pins 4 and 5 join together, and unenergized the reading is really low. Its just when i fire the system up it changes, in quite a big way. Its as if once the dash/fusebox/incar systems are ready to work, there making the resistance value change. Never seen this before, and tommorow im planning on a quick test between pins 4 and 5, and if that does the same, im considering chopping the cable to pin 4, extending it, and putting it dirrectley on to the earth point. See lexia uses pin 4 only, not 5 (which is beyond me tbh)
