Where under hood to tap for L/R Mirror Turn Signal + ?

[askdrtodd]

Hopefully this is quick and easy for someone, just looking for where under the hood I can tap the + wire to get the sidemarkers in the headlights to blink with the side mirrors (and only then, remaining off otherwise)? I tried running them with the yellow wire for the turn signal + but that's always hot, just trying to get my morimoto XB headlights to have the sidemarker only come on with the turn signal.

Thanks!

I've seen this thread, but I'm looking for the connection in the engine bay, not in the cabin of the truck if possible...?
