Ok I'll have to buy new rear ones and throw them on and hopefully it's happyno they just need to be connected, no resistor, resistor goes on the shock's only, all 4 corners
the suspension system is more than just shocks it also gets information from the ride height sensors, abs, steering wheel.
**the only time you might need to do anything with the ride height sensors is if you lifted it or lowered it a lot, then you would need longer or shorter rods
