Minimal connections to power ECU?

Post by Scourge »

I just wanted to confirm something but all that we need connected to get the ECU to connect to the laptop are ECU connector E, connector A, C101 and have the RSX harness grounded near the injectors, right?

I'm just looking at the wiring diagrams and looks like A4, A5, A23 and A24 are grounding points for the ECU handled by the RSX harness.

E9 gets power when key is in ON/START position.

And A2 & A3 get power through C101-14 when E7 grounds a relay, right? I imagine when E9 gets power.

If you just want to power the ecu to program it, you can do it with just A2 and A4.
