67 back up lights help.

Can anyone tell me which wire from the column feeds the back up lights.
I've got a 67 ss with 2 spd column shift so the switch is on the column I think.
If I can check the wire at the column then I'll know if the switch is bad coz I have no back up lights. Otherwise it could be a ground issue
Thanks.

Re: 67 back up lights help.

Pink is power to the switch, light green to the bulbs.
Switch could be out of adjustment also, or, shifter could be out of adjustment with the trans detented position.

Re: 67 back up lights help.

Ok, I don't see a pink wire unless I'm color blind (which is possible).
I have 9 wires leading up the steering column.

Is there a thread that explains which wire is for what? I looked but couldn't find one.
Is it possible that the back up light switch is on the transmission?
It's a 2 spd Power Glide but not sure if it's date correct for my car.
Thanks.

Re: 67 back up lights help.

The pink and green wires aren't on the 9 pin steering column connector. They hang from a clip closer to the firewall.

Re: 67 back up lights help.

Thanks, found the green and pink wire

So, I think I have wiring issue. With the ignition on, when I select reverse the Gen light comes on, when I take it out of reverse the lights on dash return to normal (oil/brake light) but when I disconnect the pink/green wire this dosent
happen. So Im going to change the switch on the column. This one

May also have an ignition switch problem because when I jiggle the key in the on position the lights go back and forth from oil/park to gen.

Re: 67 back up lights help.

So I changed the switch and still no back up lights.
and with ignition on when put in reverse the gen light comes on.

Any ideas, anyone?

Cheers

Not sure why the gen light is coming on, but it sounds like you may have some loose wiring or ground issues if jiggling wires/ignition effects it.

Did you check the reverse wiring with a multi meter? I don't have a wiring diagram in front of me, but if I recall, the pink wire should have constant power in the ACC position. The green wire gets power when you shift into reverse. Check to see that you are getting power at the switch.

If you are getting those readings at the switch, plug in the harness, and then check to see if you are getting power at the harness at the reverse lights. If no power there, then wires may be bad. If you are getting power at the rear harness, then the ground may be bad or the reverse lights themselves may be bad.

Re: 67 back up lights help.

Unplug the reverse light connector and using DMM, measure the green wire to ground.
You should read the bulb(s) resistance referenced to ground.
If you have resistance, unplug one bulb to see if you are reading both bulbs in parallel or a single bulb. Resistance should be measured with both bulbs singularly.
If no resistance is read, then either a broke wire or bad ground on bulb sockets.
Switch also has neutral safety function as well. Switch does need adjustment when installed.
You will get GEN light with ign sw in ACC and IGN, no engine running.

Re: 67 back up lights help.

Thanks guys,
I dont have a meter, but using a test light I'm getting a completed circuit from the pink and green wire. ie: placing one end of the test light on the green wire and the other on the pink the test light lights up! This cant be right coz I shouldnt be able to get earth from either of these wires should I?
Something's earthing where it shouldn't be. I'll check the bulb holders and see if there earthed properly. Other than that something may have been connected to one of these wires under the dash that's not right because the previous owner has done some real ugly wiring under there

Thanks all for your thoughts. I'll see how I go and post the outcome.
Has anyone else had same problem?

Cheers

Re: 67 back up lights help.

Armed only with a test light, remove the bulbs and check again.
No light, no complete circuit - good.
If you have a light with bulbs removed, then a ground exists in the green wire circuit.
If no light, install one bulb, jumper a battery source to the green wire, or jumper pink to green and turn ign sw to IGN, should have test light lit.
No light, remove bulb and check center contact of socket for power with test light.
If there is power, then install bulb and check socket to ground.
If test light lights, then open ground circuit of socket to body.

No, definitely shouldn't get a ground from either of those wires. The pink wire is your power source. Shifting into reverse completes the circuit and passes power onto the green wire. Green wire feeds to reverse lights. Reverse lights ground in the trunk.

If you're getting a completed circuit with the test light, you've got ground issues.

Re: 67 back up lights help.

I'll check out those possibilities as well. Also should the car start in neutral as well as park because atm it only starts in park and I just fitted a new switch on the column.

cheers
