I mean, I'm not asking for them to parse a diagnostic flowchart, that's way too hard but any child can see what does what in that circuit from even a quick glance.

It's even worse if they've got the factory wiring diagram that is very simple and has very few components per page versus a wiring like prodemand which shoves as many components and wires on a single page as possible.

You're looking for D1 Purge VSV. Down from that is a red wire going to (F), that's hot in run B+. Up from the VSV is the ECM which switches ground. If they want to test a simpler circuit than this they'll have to look at a door ajar switch, damn.
