What's this orange fuseblock wire for?

[Alexander D.]

I see two sockets at the bottom right of the fuse block of my '67 coupe.

The left socket is labelled POWER, and the right one WINDOWS. Mine is an A31 car. I gather the red wire feeds the power window circuit breaker behind the driver's side kick panel.

But what's the Orange wire plugged into the POWER socket for?

Here is the Orange wire, pulled out from the socket.

I unplugged this orange wire from the POWER socket to try to discern what accessory it supplies power to. But unplugged, everything continues to work as it should. Just in case, I plugged it back in...

Is my orange wire something added by a previous owner? What could it have been for?

What's the purpose of the POWER socket on the fuse block?

Speed minder speedometer. It's for the buzzer power.

Rich,
Now, you've got my curiosity going. I have power windows but NO speed minder. However, I have red wires in both locations, as well.

Thanks Rick! Yes, my car has the factory U15 speed minder, but alas, it doesn't work!

Not sure how hard it'll be to fix, but is something I hope to get working one day.

When you do, do a search here( string "speed minder", using my user name and you'll details about diagnosis and repair. Typically it's just a connection problem, but unfortunately the one inside the speedometer head. There's a tiny circular spring which acts as a ground switch in the shaft. It's a poor design that reminds me of old asian made battery operated toys in the 60's. If it's a failed buzzer/relay(mounted underdash above your right knee), it may just need the internal contacts cleaned up. Either way it's a pain to work on.

Rich,

Leif A15 used Orange, as his are(they look red in photos).

I'm not sure why you have 2 Reds. Maybe something related to AC?

Rich
Edit... P.S. Those 2 fuse panel terminals are BAT+ directly from the battery and are UNFUSED. A31 has it's own CB downstream, but U15 does not. It's always hot all the way to the buzzer. Use caution.

Attached is photo of my power slot. as you can see, it has the two wires with the one with the plug taped to the other one. nothing is hooked up to it.
I have the speed minder and buzzer and they work fine.
1967 ordered new by my Uncle late in 67 as he got it from dealer on 7-7-67. I got it from my Uncle in 1980, none of the fuse wires have ever been removed or worked on
it is how it was from the factory
hope this might help

Gary it is Orange on the 65 or 66 with the hazard lamp function, but 67 hazards are integrated directly into the directional switch.

Dean, Good info thanks.

So with A31 and U15, that extra receptacle is likely for whatever Leif discovers about his other Red wire.

And, that could be a while. I strained some neck muscles, so I won't be crawling around under the dash anytime soon...especially with A/C ducting in the way.

Sorry to hear that Leif. I too have had neck issues. Pinched nerve (Cervical) in my neck. Still gets me now and then, like if I hit my head walking under the lift.

Muscles can be just as painful I know. I use a OTC medicated cream called Mobisyl. My friend in Norway with the '67 put me on to it years ago. It's Aloe Vera based. Works pretty good with no odor whatsoever.

Hope you get better soon.

Rich
P.S. I'll do some more searching for your red wire so maybe you won't need to get under there. I'm really curious too.

Re: What's this orange fuseblock wire for?

Thanks Rich. I can't seem to remember where I put my Doc Rebuild wiring diagram for the '67 and the ones in the Service Manuals are, for me, unreadable. I'm researching online to see what I can come up with. It's been ten years since the car was completely rewired with Lectric Limited harnesses...just can't recall what that second red wire was for.

Re: What's this orange fuseblock wire for?

Leif, I've gone through the AIM and all of my ideas about what your extra Red wire is. Sorry no joy.

Is it possible the car once had U15 speedminder speedometer? Maybe the orange has turned to red over the years?

When you're feeling better.....

If U15, your inst cluster would have a small terminal on the back, and also on the back a green label (U15 only, non-U15 are red) cluster assembly part# would be 6459496. Where the harness ground attached to the crossbar under the cluster, would be the buzzer mount, or maybe traces of the buzzer body mounting tab.

Kindof a longshot but I can't find what else it could be. Unless there's some aftermarket thingy leftover from a prior owner, like stereo amp or alarm etc. But Frisco would've noted that on the sheets, no? If so they used the Packard terminal housing to look like factory.

Rich,
When the car was body off frame restored, all new wiring harnesses were installed. There is nothing "extra"/aftermarket on the car. Pictures below of the back of the instrument cluster and tank sticker showing no U15. Curious.

Re: What's this orange fuseblock wire for?

Might this wire loom be the same one use for any of the 63 to 67?
If G.M. changed any item in the car that needed power but for 67 it was not used and G.M. never told the vendor of the loom to stop installing this short wire and plug, so it just got taped to the other power wire as it is in my photo?
I can only think of the 65 or was it 66 that had the rear fan ......might this be the lead for the power to it?

looking at the order form from my 67, the only item I do not have is A/C that would need power.
attached are photo of form.
all above is "stab in the dark"
