Usually, there is a wire that runs to the frame in front of the battery and another wire that runs to the frame and to the engine block. A total of 2 wires, but 3 ground locations.
One thing I noticed with my truck is that I removed the stock wire and replaced it with heavy duty 4 gauge speaker wire and increased the number of ground locations and my truck responded noticeably better.

It's a Canadian thing eh!
There are multiple ground spots that I know of, not sure if its the same for 8th gen.
2 on the upper rad support left and right, One one the RH side of the engine bay near the battery, one at the back of the Left fender, one on the right hand side lower cross member the battery hooks up to and 2 on each lower sides of the engine.

engine grounds - 91 pics 1 f 2
I have a 91 with a 5.8 (351) but they are likely the same.
I din't check underneath but pretty much what sylver91 described.These pics are not really a representation of "stock" because I have added an extra ground from the ignition coil mount / bracket when I was Troubleshooting and ignition issue (can't sday it helped but couln't hurt so I left it). I have also added a number of wires just fwd of the battery for 1 relays that control a small air horn and 2 for a high amp headlight harness Pics attached....
