67gtasanjose:
I'm seeking to establish more undersatnding of details about this rare option.
Questions:

1.) There was an early and a late version of the lamps for 1967 models. (early used a blue and red colored, backlit font as apposed to the all red, with white font lenses on the later 67's and the 68's) When did the change occur, and did this change-over differ much between the assembly plants?

2,) What was the arrangement of the lamps within the bezels? I realize the Air Conditioned cars had the panel in the console and non-A/C cars in the panel over the radio. question 2a.) I am assembling my console mounted lamps at this time and there are marker daubs on the backside of the console panel identifying the color of the correct (round) plastic connector to the lamp body, but I do not have a way of identifying the absolute location of which lamp (e.g. "PARK", "BELT", "DOOR", "FUEL" ) goes into what location. Memory serving as my only guide without a wiring diagram tell me that Top/Left is "BELT", Top/Right is "PARK", Bottom/Left is "DOOR" and Bottom/Right is "FUEL" Question 2b.) What then, also is the correct order from Left to Right on cars with these over the radio? (non-A/C cars)

It is possible we could help establish fact from fiction about these panels with more discussion of unrestored systems.

Here, I have some shots of the 2 different lamp harnesses, one for my 1967 console A/C car, and the other is of a 1967 non A/C . It is possible they are the same as the 68's but I do not have images on the 68's.
If you look closer you can see the color coded marks on the bezels. The last image, when combined with other images, shows the wiring colors at the two white and green connectors...if it helps anyone in harness restoration.
I took some pictures of a 68 Convertible main harness, door harness and front to back harness with some additional part numbers on some of those harnesses. I tried uploading them but it kicked back and didn't take them. Let me know if you feel I should try again to upload them.

67gtasanjose:
Notable details from research I have done on an early 67 San Jose and a 68 Convertible (unk. plant & production date) on the systems I have available to collect information from.
This information may OR MAY NOT apply to other 67's and 68 models. Please contribute further information and knowledge you may have. This is a working document subject to changes.

1.) 67's and 68's use a completely different main harness from each other.
2.) The RELAY is the same for both. The overall design is the same for both. Part number on the relay for all is C6AF-10A986-A
3.) 67's use a round "bullet" connector at the door harness to the main Convenience harness connections. 68's use a somewhat clear, plastic "pin" connector at the door harness to main Convenience harness connector.
4.) 67's have the Low Fuel wire built into the tailamp harness, running down the left rocker panel. 68's had this (green with white tracer) wire running down the right side rocker (at least on convertibles)
5.) The relay is close to the ignition switch on the 67's and close to the Park Brake on the 68's
6.) There is a red wire at the relay for both years, that runs out to under the hood, through a hole up high on the cowl, directly behind the furthest right bolt (of the 4) at the rear of the right side strut brace or export brace. This red wire connects (on the early 67's at least) with a male "bullet" connector into a female, 3-opening "bullet" connector, plugged into the middle hole (other 2 are not connected to anything) and runs along the pinch weld of the cowl, (through a wiring holder over the brake booster) joining the rest of the headlamp harness and runs in tandem with the headlamp harness in front of the radiator, over to the starter relay. It is connected on top of the main cable going TO the starter. (functions as a bulb-test in "start" to the FUEL lamp)
7.) Early 67's used different lamps than the later 67's and the 68's. Production changes are unknown at this time when they switched to the later type. These early lamps had a blue "font" for the DOOR and FUEL lights while having a red "font" for the PARK light and the BELT light. I say "font" because they were a blackout round lens till they were backlit, and they lit up only the font in the colors mentioned. The later 67's and 68's (currently being reproduced by Scott Drake) were all red lenses with white lettering on the faces. You could tell what they are for, even before they are lit, where as the early design was more incognito.
8.) These lights were in different locations depending if the car had Air Conditioning or not. A/C cars had the lights in the mandatory console (to have this option) Non- A/C cars were all over the radio (where the AC register would be on the AC cars) and did not require having the console to have this option.
9.) There are different door wiring harnesses depending on other options ordered. (e.g. with or without stereo door speakers and with or without door courtesy lamps)

Feel free to add more info about this option. There is little discussed anywhere about proper restoration methods. Where they tape to the main vehicle harness, where the relays mount on various productions and so on.
Please help shed light on other areas you may be aware of.

I have a 67 GTA convertible with the Convenience option. It was built 11-04-66 and has the early lights. One thing I did not see in your text is the door ajar indicator uses a special bulb that flashes, it is now obsolete so NOS is your only option. The reason I understood that it flashed was if the door was left open for a long period a regular bulb may melt the lens.

Interesting about the bulb. One of my early lenses is warped some from heat...but it's the PARK lens.
I'll have to test my bulbs, see if we have any "flashers" among them ;) You wouldn't by chance have a bulb number on that, do you?
