Unless there is a decent thread already going - that results from search function using words like 'EA82 ECU test plugs'- can we make this a PINNED thread please and just add the links as people find the info spread about this resource ?
Going silly looking at the moment
I was reading some good, actually, well written threads only just yesterday, now, cannot find them.
Was likely by Gloyale, contained precise instructions as to what the green test connectors, the black test connectors do and the how, why and when to plug, unplug, read etc, etc. The factory manuals do not say green plug does this, black plug does that, just refer to 'connectors' . The thread was better written and fool proof. Thought I bookmarked it
