    One for the electronics geniuses

    What i'm needing is a relay that'll run off almost no amperage (the shift light circuit on the link , designed to run a LED) and switch a current of enough amperage to switch a normal 12v relay...... Any Ideas????

    Could use a transistor to switch the coil on and off (works like a relay with no moving parts).

    /edit: Oh yeah, just use a big transistor (fet)

    Lump lingered last in line for brains,
    And the ones she got were sort of rotten and insane...

    Check with Link, that output may be able to drive the relay directly.

    Which is what the kit does, plus its only 4 parts on a nice easy kit, only thing is it looks a little bulky, plus its only 12 bucks

    Agreed, nice little kit, perfect for what he needs (assuming he is planning on running a big fat light off of it)

    /edit: What are you planning on doing with it? NOS solenoids might need more current than that relay provides?

    Could it be to pull the clutch in?
    Speed limits are just a suggestion, like pants.
