Side A of the Elite 1500 and 2500 quick start guide is a one-page wiring reference for these ECUs. Here's what it's for and how we use it on an install.

The Side A quick start sheet is a condensed, printable reference for the Elite 1500 and 2500. It's meant to sit on the bench or the fender while you wire and power up the ECU, so you can check connections at a glance without digging through the full manual.

When you need it

  • While terminating a universal harness or checking a pre-made one.
  • During first power-up, to confirm power, grounds and key inputs before you crank.
  • When fault finding, as a quick cross-check against your harness labels.

What to check with it

Confirm you're looking at the right ECU model, since the 1500 and 2500 differ. Verify the main power and ground connections first, then trigger inputs, then everything else. For full pin-by-pin detail, use the Elite 2500 26-pin, Elite 2500 34-pin and Elite 1500 26-pin wiring diagrams.
