Versa "S" model stereo?

[Versa-Fied]

Is the wiring diagram the same for "S" model as it is for the "SL" model? I want to install an amp and subwoofer while retaining the factory installed headunit.

The connectors are the same, yes, but there are some slight differences in wiring.

On the SL, there will be a crossover and two speakers on each front side, vs. just a single speaker per side on the S. Also, some SL models have the wiring for the satellite and bluetooth (probably shown on the wiring diagram). These will be missing from the S.

Hope this answers your questions.
