Where to ground to check ignition timing??

[RotaryRyan]

Hey, i have a 95 gst and i see that to check the ignition timing you have to ground something under the hood. Anyway, all of the pics and vfaqs seem to be for 1g's and the pics are too small to see anything. So how do i find this thing? Imthink my timing s a litlle off. Im getting alittle bit of a weird sound that might have something to do with it.

Thanks

If anyone has a pic or something id appreciate it.

cmon, it looks like it sits at like 10* but it jumps all around so i cant really tell. So i need to ground this thing

its against the fire wall,kinda in the middle(location depends on who messed with it last)they call it a "snake eye plug"and it only has one wire going to it,the plug has a cover on it,basicly looks like a "dead end" plug(nothing hooks to it)
