The Elite 1500 has two main connectors, and this diagram shows the 34-pin one: which pin carries which input, output, power or ground. You'll need it whenever you're building a wire-in harness, adding a sensor or output to an existing loom, or tracing a fault back to the ECU.
When you'll use it
- Planning which spare inputs and outputs to assign in ESP before you start wiring.
- Pinning a new connector or repairing a damaged terminal.
- Checking continuity from a sensor back to the ECU during fault finding.
What to check
- You're looking at the 34-pin diagram, not the 26-pin Elite 1500 connector, and not an Elite 2500 page.
- Which side of the connector the diagram is drawn from, so pin numbers aren't mirrored.
- Every pin you use matches its assignment in ESP.
For the full connector layout, see the Elite 1500 main 34-pin connector page and the Elite 1500 overview. More diagrams live on our wiring diagrams page.
