I looked through my 87 electrical service manual which shows the location of the chassis grounds and was not able to determine what device that ground wire is for. You can follow the wire and determine what device it is ground for.

there are any number of grounds on the 87s.
One goes to the block, a couple, to the back of the right head.
The one to the block is the main neg battery post ground.
The ones on the head? I am not sure what exactly they do... They do come from the harness, tho.

Doesn't really matter what they're for unless you're chasing a certain problem. On my '95 there were 4 or 5 on one tranny bolt which made things even more of a PITA to unbolt the engine along with the stock cat brackets, which no longer exist. I relocated all of those grounds upon reassembly, some to the back of the left head and others to an unused threaded hole on the left side of the block. Just make sure they're all clean and making good contact and have no excessive resistance.

Good Idea Corvette Kid NC,
My trans will be back from the rebuilder on monday...
I was thinking the same thing, it maybe easy for asembly lines but a real pain to get to once the car ins on the ground with the trans back in it...
Mine is a 96 and I know has the battery ground and about 3 -4 others I'm guessing from the ECM engine etc. etc.

Bad ground cable?
I'm having a problem on my 84 where my battery is draining overnight. I put in a known good battery and measured for voltage drop and founmd I had 12.48 volts measured from the negative battery post to the negative main ground cable!
I checked all my fuses while looking at the voltage but it never dropped so I suspect maybe a bad gound cable???
Any advice appreciated.
