The PCM is located under the glove box.


These are the PCM pins used on a 2001 V6 Tracker. Chevy calls the PCM connectors C1, C2. C3 & C4. Suzuki calls them E61, C51-3, C51-1 and C51-2

In the Tracker service manual the PCM is chopped up into a hundred little pieces. Those pieces only show up on the
pages of the systems that use them. The Suzuki manual sees the PCM as the heart of the car. The systems revolve
around the PCM. That concept was driven home by this drawing in the Suzuki manual.


I took that concept as far as I could with this PCM composite for my 2001, 4WD, V6 engine.
