Tangentially related, but when people talk about removing the switchover valve and installing an overboost warning light, are they tapping into the signal at the valve? Anybody know which wire?

Also, isn't boost limited by the switchover valve acting on the ALDA to cut fuel when it sees too high of a boost (15psi or so I believe)? That valve seems small to do the job of venting a lot of boost, so that's what I always assumed. Perhaps I've been understanding it wrong all along.
