So, as many folks have done, I put a non OEM track seat in my 2012 s197. Now, I could spend the relatively low smooth of money on resistors from kohr, but I like doing things myself - some call it being stubborn.
Anyways, I cut the plug off my original OEM seat and figured “oh this is easy, solder a 2ohm resistor into it and your done”. Well, I’m a bit puzzled. I put a 2ohm in, and it read low 1’s. I put a 3 ohm in... same result. I put 2 3 ohms in series..... still reading about 1.2-1.3 ohm. I am at a total loss. Has anyone cut one of these open? Is there some weird trickery going on with a secondary circuit in parallel!? I’m getting marginally higher resistance readings then what my meter reads touching prong to prong as if the plug is shorted out. It’s not shorted (from my doing anyways) and I have triple checked my revisited prior to soldering. What exactly is happening!?! It’s driving me nuts.
Also, relates topic, but how on earth does the seat position sensor work? What is it sensing exactly? Seemingly it’s always the same distance from part of the seat slider, so is it just looking for movement of the slider during the impact of the crash? I can’t figure out how it “knows” how close or far you are from the steering wheel, all I can figure is it looking for movement during the impact itself. Anyone know? I just zip tied it to part of my seat base in an attempt to trick the system into thinking things are normal, but I’d like to know what exactly I am tricking...
