Ground wire?

I rebuilt my v8 4.7L engine and there is one ground wire i cant seem to figure out its spot. Its in between the pcm and the firewall. About 14 or 16 gauge wire approx 18-26 inches in length. Its bolted on the rear of a black mount. The pcm pin plug also sits above this thing.

If anyone could pop their hood and take a quick look that would be great. thanks

Re: Ground wire?

Ok I pulled both computer units out( the one in front of the pcm and the pcm itself). The ground wire off the pcm itself is the ground wire that I need to ground. Does anyone know where this goes?

Re: Ground wire?

On my jeep there is a bolt on one order that holds that wire grounding the PCM then I'm pretty sure it runs to the frame on the battery side or gets grounded on the negative side of the battery.
