OK, here's my mystery. The car 85GT V6 A/T. I'm completing a schematic drawing of the engine harness as a whole to include wire colors and the actual shape of the connectors. This way I don't have to shuffle thru a bunch of pages to get to the proper end. Every wire will be on one big sheet (approx 33" x 42") that I hang in my garage for trouble shooting. I made one for an V6/automatic, one for a V6/stick shift and another for a V8/carbed version without an ECM. From there I can modify another drawing to suit a different swap. Don't get too excited, I'm not releasing them, YET. I found a couple of mistakes in the 1st version. While playing around and tracing all the wires as per my drawings against the harness, I find that the deck lid release connector (1 wire blk/wht) that is located next to the driver side hinge is not in any of my books. I have Haynes (all years), Chilton (all years)and Helm (84 and 87). Now I think the 84 is totally different because it did not come with a V6, but I checked it anyway. I physically traced this connector wire to pin A1 of C500. Yet the 87 Helm book lists it as (Not used) on 8A-202-1. I will add it to my drawings, but I think I missed it. I went thru every page in the 8A-xxx-x section with a magnifying glass without success. The closest I got was on page 8A-134-0 showing connector C250, that's a four wire connector. Is there someone with an 85 book that shows this connector in the schematic. I need the connector number such as Cxxx and a pic of it like the ones in section 8A-202-x. I hope I was clear with my description. TYIA.

You mean the switch on the wires going to the deck latch? Three wires go to the switch on the latch. The 4th wire goes to the power release solenoid. The solenoid grounds thru the latch hardware.

The three wires that go to the latch... If I remember right, one is a ground the others are Ajar and Trunk Light.

The Ogre's Fiero Cave (It's also at the top of every forum page...)

Appreciate the response Ogre. Here is a pic highlighting the connector.

What's your thought? Thx.

The connector is located on the Passenger side decklid hinge, not the driver's side. At least it is on my 87 GT.

Avengador1 - I had to go verify, but it is definately on the driver side. My 84 is also on this side. As a reference the f/p and a/c relays are located on the driver side and the connector is only about 6 inches away. The black plastic clip midway down the conn wire is pushed in a hole on the hinge support. Now mind you, I'm saying it's for the the lid release cuz there's only one wire going up inside the trunk lid and ends up at the solenoid in blk. Is it not??

Edit to add a pic from 87 Helm service manual

It also shows it on the driver side. My wording must have been unclear.

The deck lid release system wiring varies by year and maybe by lid...

The later coupes that have the Ajar switch on the latch have the connector for them on the passenger side hinge. It is a flat 4 wire Weather Pack connector wired as I noted above. I think it is the same for the later GT lids.

The older coupes had a pin switch for the Ajar and trunk light mounted on the edge of the trunk. I haven't seen how the power deck latch is done on these.

I can't make out the connector in the picture above very well. It does seem to match what is showing in the manual page and the only thing in the older lids would be the trunk solenoid if you have that option so only one wire...

I picked up a free 86 GT which had an engine fire and is missing the rear deck lid. I've had the car for two months now and had been wondering what that four port electrical connector attached to the passenger side deck hinge was and where the other end had gone. Now I believe I know. I hope when I find a deck lid it has this connector.

84 and 85 had a single wire connector on the drivers side hinge box for the deck release. In 86 it was moved to the passanger side and incorperated the trunk light switch wiring which was moved to the deck lid latch also in 86.

I'm not sure on what rubyred is asking, but the connector number for the 84-85 model is C402, you can find the wiring schematics in the HOOD, TRUNK, AND DOOR AJAR AND TRUNK RELEASE section of the Helms manuals. Page 8A-135 in my 84 helms manual.

Well, while you wiring gurus are all here.
Has ANYONE ever found the fuel pump test connector that is "supposed" to be near the driver's side decklid hinge?

I quote:
"The fuel pump test terinal is located in the left side of the engine compartment. (see illustration 3.6). When the engine is stopped, the fuel pump can be activated by applying battery voltage to the test terminal."

It even shows a picture of it hanging right between the driver's side decklid hinge and the fuel pump/A/C relays. I've yet to be able to find it on any fiero. Yes, I know you can test it at terminal 'G' on the aldl.

Could this be your mystery connector? I have heard that is was intentionally stuffed behind the insulation on the firewall and had to be poked and prodded into showing itself. The one you highlighted looks just like the one in the illustration in my very old Haynes manual.

Don, I've never heard of or seen a fuel pump test connector in the engine bay of any year Fiero. I test using the fuel pump relay connector.

Well, my haynes is about 10-12 yrs old. Only place I've ever seen it mentioned. They took the picture from somewhere--but where? That's clearly the deck hinge on the right side and the 2 relays on the left. Here it is:

That sure looks like the decklid release solenoid connector buddy is holding in that picture. What kinda manual is that? Anything other that Helms manuals are known for incorrect info.

EDIT, just noticed you said it was a Haynes manual.

The Finale is based on an '85 and both the race car and new project car are '86 models. The connector you highlight is the rear deck latch release connector. The ajar/trunk Light are both connected with tiny connectors on the pin switch itself and have no other connector that I can recall. There is just one wire going up into the lid structure. The way we did the Finale remote release we moved the solenoid/latch to the trunk itself, making it stationary, so I had to move that wire as well.

To find the connector number you're going to need an '85 factory shop manual, most likely, for it to show up. Most of the connectors on my Mitchell On Demand CD's are not numbered.

Personally, when it's just a single wire connector, I don't see the purpose in even GIVING it a number, just show a connector at the proper location in your wiring diagram. Since it's the only one there, it's not like you can hook it up wrong.

I certainly agree with all that. Haynes should have been typed up double spaced to make it easier to read between the lines. That's why I have a Helms and GM shop manual.

I have an 84 and the conector is definitely on the driver's side, the only problem on mine is the wire is just hanging there from the decklid and I don't see a matching connecter anywhere.

Where is the connecter on the harness located?

Just went and looked. On both our 84s, there's a harness about 3/4" thick that runs under the left decklid hinge support, and then on around the vac canister and to the cruise control.
The decklid release wire (a pigtail actually) exits that harness about 1" to the right of the decklid hinge support. A single black wire with white stripe. It's actually supposed to have a little gizmo on the connector to fasten to the left side of the left decklid support. You may have to open up the split harness covering to find it.
edit:You can barely make out the harness running left to right under the guys hand in this picture. Your wire exits from that area.

Jelly - I concur the 84 Helm manual shows H8 as the trunk release. I have the car and the book. I have the 85 car but not the book. The connector which is also on the driver side leads to A1 on the C500. Comparing it to the 87 Helm manual, A1 is not used, H8 is white for exterior lights and no assignment for a trunk release. The word "trunk" is included in F8 as part of the instrument cluster. With all the info that is supplied by all it is evident that there are quite a few differences amongst the years, and it's best not to include the wire in my generic wire diagram.

Jscott - I think your question of where the connector comes out of the harness can be answered in the above picture. The harness comes out of the firewall via that gray/black collector. Looking from the trunk side at the wire loom it goes left to below the driver side hinge and that's where the wire is. Following that comes the a/c and fuel pump relays. For some reason I'm thinking that you already know that and I read your question wrong.

To All - This has been very informative (thanks to PFF), I did not know there were so many variables on just one item. This forum is definately serving it's purpose, cuz if I included the wire in my diagram, it would have been the wrong information at a later date to an innocent recepient. Thank you all, I got enough info in my thread. Final answer - there is no one common place where the connector wire ends at the C500, because of changes that transpired during the five year build of our Fieros. Thanks again.

I compareed my 85 (which had the trunk release from the factory) to my 87 (which didn't) the connecter on the 85 is on the drivers' side and the 87 has the flat four connector on the passenger side, but no wire on the trunk lid (just three)... I guess I'll have to run that on my own for the conversion I am doing- unless someone has a good 87 power trunk they'll give me here in VA.

Maryjane - I've been looking for that fuel pump test connector for years, myself. My deck lid release connector didn't have the plastic on it by the time I got the car, so I wasn't able to write it off as being that. I simply thought it was missing and even cut the whole loom open trying to find it.
