""It is easy to figure out the four wires, all you need to know is use multi-meter to identify the ground, and the two same color wires are for heater, and the rest wire is for signal! Use the above method you even do not need to care what color the wire is. I solder the sensor wire with the old wire, because I do not trust the clamp."" posted by: mountainman on September 1, 2014

    Cadillac STS: The Replacement for the Famous Seville

    The STS was Seville's more compact yet less evocative successor. It was initially introduced in 1988 as the Seville Touring Sedan package, an enticing performance-oriented Seville version that included General Motor's FE2 Touring Suspension. In 1992, it became Seville's trim line along with the Seville Luxury Sedan (SLS), and in 2005, the STS nameplate eventually replaced the Seville. Throughout its industry existence, the STS was Cadillac's most expensive sedan.

    2005: Launching of Cadillac STS

    The Seville retired for the 2005 model year and was replaced by the new rear-wheel-drive STS, which was based on GM's Sigma platform. RWD was standard, but an AWD option was also offered. The STS derived its power from mighty engine options--the LY7 V6 engine that's capable of cranking out 255 horsepower or the 4.6-liter Northstar V8 producing 320 horses. Both engines were paired with a five-speed automatic transmission. The luxurious STS trims offered a standard remote ignition, which attracted many buyers.

    At the 2005 Detroit Auto Show, Cadillac introduced the STS-V for 2006 model year. This variant was equipped with a supercharged 4.4L version of the Northstar V8 engine that's certified by the SAE to generate 469 horsepower and 439 lb ft of torque. A year after, Cadillac unveiled a stretched version of the STS, named SLS. This was manufactured at GM's Shanghai plant and was revealed at the Middle East International Motor Show held in Dubai.

    2008: The updated Cadillac STS

    For 2008, the STS received a facelift as well as a few interior updates. The redesigned STS, which debuted at the 2007 New York Auto Show, got a larger, more aggressive grille, chrome fender vents, as well as new steering wheel. The standard engine was a direct-injected 3.6L V6 matched with a six-speed automatic transmission that was able to produce 302 horsepower and 272 lb ft of torque. More safety features were also added, including the Mobileye blind-spot control system and GM's StabiliTrak stability control system.

    For 2010, the significant updates done in the STS were the removal of the GM badges and the introduction of trim levels--the Luxury Sport, Luxury, and Premium trims. The following year, the V8 engine was dropped from the STS.

    2011: The final Cadillac STS

    The 2011 STS concept debuted in January 2010 at the Detroit International Auto Show. This new, long-wheelbase, single flagship sedan was aimed to conquer the upscale midsize luxury space that was long dominated by German automakers. This new STS was offered in V6 Luxury Sport, V6 Luxury, and V6 Premium. The V8 engine option was dropped, leaving the V6 as the sole engine across all trims.

    But being a middle child indeed has its own share of disadvantages, especially if you're sandwiched between CTS, which is Euro-flavored, and the famous DTS land yacht. The 2011 Cadillac STS found it difficult to win the hearts of luxury sedan customers, even if it got a new V6 powertrain and it retained its athletic handling, let alone its having popular rivals like the BMW 5 Series and the Mercedes Benz E-class.
