I have an aftermartket tachometer that id like to hook up but i have no idea how to do so, i figured id watch some youtub videos but id rather have a direct answer for my vehicle. Also under the hood it says the rpm's at "curb idle" should be "750+100 rpm" and im not so sure what that means, i think im idling a little high probably 900-1000 but i also have yet to set ignition timing since replacing the head gasket so i have to do that next, anyways thanks in advanced for the help everything is much appreciated😃
