Radio Interference thing?

[Toms01PSD]

When I did the head job on my truck I removed the radio interference connector/ground whatever the hell it is and I can't remember where the hell it's connected at. Right now i've got it grounded to one of the coil pack bolts and i'm tired of hearing it fire...It's a 98 4.0. Some direction as to where it goes or a picture would be greatly appreciated fella's!

there should be a single wire connection that it plugs into and the radio supressor should be fastened down with the coil bolt.

So it is suppose to be where I have it already? That's odd because I can hear it firing with the engine running while the radio is on.
