MEVI...use a relay, or no?
I'm going to hook this thing up finally. I vaugly remember relay vs. no-relay threads a while back, but couldn't find them.
Is a relay necessary? Can the Harlen switch handle the ground needed by the MAP (GM) switch?

use a relay. there is no reason not to.. it is a couple dollars, and if nothing else, better safe than sorry.

The reason people are getting away with not using a relay is because the vacuum solenoid has enough resistance built into it to keep the current at a safe level for the Harlan. If you tried to power something like a high wattage light bulb (for instance) directly from the Harlan, you'd fry it.

no relay here for over 6 months and my harlan/mevi works great. the harlan can handle the very small amount of ground needed for the map switch to work. it is not that fragile, sprint uses it for a nitrous solenoid and that is sure to put more current strain than a tiny map switch, just don't let it get wet.
