Ignition noise suppressor
I must have left this disconnected nine months ago. Can anyone clue me in as to where it is fastened? I thought one of the coil pack screws, but I'm not sure any of them is grounded -- it's been too long since I had the coil pack out.

Hmmm. It's not obvious how the exhaust manifold has anything to do with grounding there. The coil pack bolts to the intake manifold, but they're both plastic. There's a ground shield plate between the coil pack and the intake, but it does not appear that the coil pack screws ground to it, although I only pulled the right rear screw tonight; perhaps the left rear screw grounds.
Anyway, thanks. I'll probably pull the left rear screw & look at it. With dual-A/C & dual heat, there's lots in the way back there, but I've had the intake & fuel rail off twice so I know it can be done

bottom stud/nut on the triangle coil bracket where it attaches to top of head above back exhaust runner to exh. manifold.
at least that's where my 96 manual and old fuzzy memory says.
never made a difference on mine if connected or not. AM reception has always been ign. noise hampered since new. new M/C ign. wires and new Autolites never made any difference, nor did cleaning and greasing all chassis gnds.
it's the fiberglass hood and ineffective RF screening and grounding of the poor screening. even ran a flex grd strap from hood shielding, waste of time.
FM reception only rig or just listen to the hard drive player
