20 years ago, I installed one in my Formula. As I recall, the wiring was all there. Just needed a switch and deck latch/solenoid. (got from ebay at the tiime)
On a separate note I have an 85GT in the shop that we are trying to restore. For the engine swap we dropped everything out but we can't locate where the trunk release cable plugs in along the firewall. On later Fieros its usually on the right side of the firewall. Could it be where the truck light connection is near the left side wheel well on the 85's?

The 85gt is a single wire connection on the left hinge by the wire for the decklid metal shield, it is a square connector with one wire. It only needs one wire (power for the solenoid) because the latch is the ground and the early Fieros have a trunk light switch by the cruise control, later Fieros had the switch in the latch, and multiple wires going to the decklid.
So if my car (88 Duke auto) didn't come with a trunk release button what all would I need to install one?
I installed one in my 87 Duke (Same as the 88) and I just had to add the relay underneath the dash, the release switch and plate on the instrument pod, the power solenoid on the deck lid, and I had to snake a wire down through the decklid reinforcement rib, to the passenger side hinge area. I secured a short piece of wiring harness with the proper terminal end at a pull a part, spliced it onto the end of the wire and plugged it into the empty socket of the decklid terminal that's beside the hinge.

gonna hijack this thread a little. how did you snake the wire through and are the lock rods any different?. also does anyone have the wiring diagram for the stock trunk light? gt or the late coupes
My two cents regarding an aftermarket installation is to route the latch solenoid through switched power. For me at least, it bugs me that the switch stays live with the key out of the car. If it were on switched power, the trunk would be more secure.

I have a roll of 1/8 bare single strand aluminum wire that I formed a small loop on the end to keep it from snagging. It's flexible but strong enough to push through. I pushed it through from the latch end. Once I got it to the hole at the hinge area, I placed my insulated wire end into the loop, taped it securely and pulled it back through. I don't recall that I had to change the lock rod. I think the only difference in lock rods is between the fastback and notchback locks.
The trunk light wiring should already there on the 87. You should see a wire going to the switch on your latch. It runs up through the same rib as the latch release.

this is for the 88 that's never worked right. much appreciated as now i just get to find the release connector
