Yes, take the purple out of it's current position and relocate it to the un used slot as marked in your original post. The 64 - 67 switch has the same un used terminal.
Hence, No need for the new switch...Trust me, I've done it!
Yes you are correct.

I should have been more clear in my description--you may then use a 1968+ switch if that is what is accessible to you if need be once you move the purple wire. If there's nothing wrong with your pre '68 switch or were able to get a new pre '68 switch, then just moving the purple wire feed does just fine. Sorry for any confusion.

Re: Helpful Headlight Switch Info

never mind guys I found it, The dash strip I bought from a reputable dealer was the correct dash strip except the headlight hole has a raised boss on it keeping the headlight switch pulled out just enough for the park light to stay on

Great write up. I need this. Didn't even realize turning the switch would increase the output of the dash.

Now is there also a way to add a high beam to this or maybe relocate the foot switch?

Re: Helpful Headlight Switch Info

Wouldn't installing a diode between the park power wire and headlamp power wire prevent the park lights from turning off? Wouldn't have to buy a new swith either.

No need for a diode, no need for a new switch either. There was some misunderstanding in the earlier posts. This "mod" can be done to the pre-1968 switches or if a 1968 or later switch is only available to you at the time of your project on your pre-1968 vehicle, then that switch can be used following the same directions involving the purple wire move.

Re: Helpful Headlight Switch Info

great info to have,,


the green wire you mentioned going down to the fuse panel does power come out of the switch down to the panel through grey up to cluster ? having issues with my 70 and no power is at that fuse at all. I think that's causing my idiot lights not to come on when the key turned to on positon as well as not sending signal down to regulator via brown wire causing alternator to charge.


it had me going in circles yesterday until I read your post..


thanks Joe

Rob,

The green wire feeds power down from the dimmer control on the headlamp switch to the small "stubby" fuse in the fuse block labeled "INST LAMPS". It will only have power when the headlamp switch is pulled out to the first or second position and the dimmer (the knob itself) is fully rotated to "brightest". This fuse protects the dash lights (illumination at night). The wire leaving the stubby fuse is grey and feeds all the illumination lights through the dash.

The dummy lights and excitation circuitry are on a different circuits. The "gauges" fuse protects the power side of the dummy lights. The brown wire gets power via a resistance wire (brown with white stripe) inside the dash harness. Even if the "GEN" lamp is burned out, the brown wire will still get power as the brown/white is tied directly to the ignition switch.

If you need more help, I suggest you start a new thread.

Re: Helpful Headlight Switch Info

thanks Joe,,

I will check that green wire from switch to fuse panel and check the gauge fuse wiring you mention. I take it the brown/white striped wire gets its power from igniton switch to the dummy light as you had mentioned. I have opened up the fuse panel to check for corrosion in behind.

I will let you know what I find. Thanks for the help and info

Welcome Greg.

Best to start a new topic post on this. A lot of issues with cars after "paint" is ground connections are lost at key points.

Know it's 4 years later, but still extremely helpful! Couldn't figure out why my new switch was dropping the front parking lights on my 64. Thank you for posting this!

Re: Helpful Headlight Switch Info

Great Write-up.
Would you say that if all lights work correctly but the dash lights will not dim . . . the rheostat is shot?

Re: Helpful Headlight Switch Info

Is there any reason for a feedback thru the headlight switch to keep the keyed hot extra terminal on the fuse panel hot, even with the ignition switch off?? Using that terminal for my fuel pump relay 12v signal and pump keeps running till the lights are off

Re: Helpful Headlight Switch Info

Can anyone do me a huge favor and post a picture running their low beams, and a seperate picture of high beams? The original builder of the car I just bought decided to screw up all the wiring beyond belief, and I am not sure how the headlights should be working. My question is when the center high beams are on, should the outside high beams be on as well, or should the outside headlights be running on the low beams.
