    I just changed out the alternator on my 2008 Tundra Limited 2WD but accidently pulled out the wires to the plug to the alternator. The alternator has the wiring diagram as IG, S, L, and M.

    I'm seeing these wires but which one do these go to?

    assume.. makes an ass out of u, but not me as a ssgt would instruct us..... you should really verify your engine. it's either a 4.7 or a 5.7... They may be similarly wired, but do you really want to brick your truck?? I wouldn't.. Electrical gremlins are expensive
