Questionable Wiring in '67 Camaro Conv'

I'm installing a new shifter to support the new 4-speed auto transmission with overdrive. Part of the installation is to ensure the neutral safety and the backup lights are operating correctly, as neither of them were connected before.
I understand the neutral safety is a pair of purple wires that lead through the console wiring. I find one of the purple wires has a red wire attached that leads back to the fuse box and there crimped to a purple wire.
I suspect this rigged wiring was to bypass the neutral safety function since the removed shifter had no switches in it. How to correct this? Does someone have the wiring schematic they can share with me?
I am hoping I can connect the loose purple wire and the questionable red wire to the purple leads of the shifter to gain the function of the neutral safety.
(I don't know why that 3rd photo of the wiring behind the fuse box insists on posting upside down)

Re: Questionable Wiring in '67 Camaro Conv'

Just been thinking about this....

If the red wire is a jumper to close the circuit then I should connect the two wires under the wire nut (red and purple) to the shifter purple wires to allow proper function. Without unwinding the harness I may not know where the other unutilized purple wire routes.

Re: Questionable Wiring in '67 Camaro Conv'

Andrew, The orange and white wires in your 2nd pic need attention also. I'm
fairly sure they go to the parking brake switch. I'm thinking the red wire was
used to replace a bad purple wire so I don't think it's a bypass. I'll send you
a PM with colored wiring diagram. I'm not sure where I got it from but it's
been accurate for me.
Edit: Seems I can't attach a file to a PM so PM me your email address.

Re: Questionable Wiring in '67 Camaro Conv'

To bypass the switch all you would need to do is jumper the two purple wires together so I'm not sure why the PO was doing. One purple wire goes to the start terminal of the ignition switch and the other wire makes it way to the starter solenoid. The green wire from the reverse light switch goes to the 10-pin connector and the other side of the connector goes to the reverse tail lights. The pink wire goes to a flasher. I sent you a PM with a link to a wiring diagram, I guess I don't have anymore bandwidth to post it in this thread.

Re: Questionable Wiring in '67 Camaro Conv'

Thank you Al and thank you Lee. The diagram Lee provided is for a '69 model and probably very similar to the '67. I'm thinking too that the red wire was to replace one purple and then they were wire nutted together since the shifter didn't have the switch. So I should use the two wires that are presently joined to connect the shifter's wiring.

The orange and the white wires go to the light at the rear of the console. The e-brake switch is connected with a brown wire that I believe is correct.

Re: Questionable Wiring in '67 Camaro Conv'

Oops, sorry about that, I read your username and thought we were talking about a 69. I should have read the subject line more carefully. I sent you another link for the 67 wiring diagram.

Re: Questionable Wiring in '67 Camaro Conv'

You're welcome Andrew. I should have said brake light switch not parking brake
in my previous post. You'll see it in the lower left corner of the wir1.jpg I sent.
If in your case it goes to the rear console light then so be it.

Re: Questionable Wiring in '67 Camaro Conv'

So I have worked through the earlier concerns and now moving to the emergency brake switch and light. I noted the brake switch paddle that depresses the switch is missing meaning the circuit remains closed and the light would remain on. I'll order another paddle to rectify the switch depressed concern. I noted an orange and a white wire clipped under the dash behind the speedometer. Do these power the brake light and might they have been clipped to darken this bulb?

This photo shows circled the orange wire that I earlier rejoined with a wire nut that provides power to the clock.

The arrow points to the orange and the white wire that is clipped. What do they power? Should they lead directly to the bulb?

Re: Questionable Wiring in '67 Camaro Conv'

Pretty sure they are interior lighting. Or Door switch for interior lights. I purchased the under-dash footwell light kit and they were all orange/white..

Re: Questionable Wiring in '67 Camaro Conv'

I guess they could be interior lighting. This car has the footwell lights and I don't think they work. I'll trace them back. I'll also check if the brake light outlet contains a bulb.

Re: Questionable Wiring in '67 Camaro Conv'

Andrew, Look in the upper left center on 67wir2.jpg I sent. Looks to me like
the connector for the courtesy lights. 1 orange and 1 white splitting into
2 orange and 2 white.

Re: Questionable Wiring in '67 Camaro Conv'

So I spliced in a new socket for the courtesy light from the orange and the white wire. I find two more wires up there that have plugs to be connected but they’re connected to nothing. The brown wire and yellow wire hanging down.

What might these power? I suspect the brown wire is to the dash brake light but I find no obvious place to connect it.

Re: Questionable Wiring in '67 Camaro Conv'

Could the yellow wire be for radio power?

No, the radio wire was in the area of the radio even thought it was not connected. This yellow wire in question would not reach the radio area.

Re: Questionable Wiring in '67 Camaro Conv'

Andrew, There is a brown wire that goes to the emergency flasher in that area.
It goes in a connector with a black wire shaped like an "L". That may be where
your brown wire goes. It sure looks like it's been removed from a housing such
as that.
Add: My radio power lead is identical to the yellow wire and connector you show.
I see no other yellow wire in that area.
