1966 Corvette Fuse Box Photo - Red wire for Power Windows?

[Tom D.]

John Hinckley posted this photo back in 2000 on the CF. It's a 1966 Corvette Fuse Box Photo; Related to a. request for such a photo, not related to a PW discussion there.

Does the red wire indicate Power Windows? Or, some other added accessory?

EDIT on 5/18/25 by TD: Page 57 of the TIM&JG (6th ed.) indicates a "double wire" connection at this same spot on the fuse panel. Figure I 14-4.
I assume that is what a OEM PW power source should look like. And, not like this:

That's where the feed to the PW circuit breaker on our '65 is plugged in. I think that photo was from our car.

65 here looks the same as the picture. The red wire is part of the power window harness.

On different ‘66s, I’ve seen the red wire for the power windows in the lower right hand slot. And I’ve seen a double orange wire in the lower left hand slot for the 4-way flasher.

Not a 66 guy, but the AIM show the plug slot?

Not sure if it makes a difference, but the picture below was from my '67 with power windows. Picture was taken to show the A/C ducting, so the fuse box is barely visible, but the two red wires in the "power window" slots are visible. The wire on the left was for the power windows and I don't recall what the red wire on the right was for...possibly, hazard flasher.

Gary, Yes.....

The 1966 AIM shows the RPO V74 Hazard Lamp wiring into the panel. It's a Orange wire connector with a separate extension with extra tap. I think the extension may have also been used on Passenger cars or Trucks as well, and they may have had limited fuse panel taps.

Leif, The Hazards on a '67 were part of the Directional switch and had no feed from the fuse panel. The feed was built into the Main Harness. Did your car have RPO U15 Speed Minder Speedometer? If it did, it was a Orange wire there. It also had a dual connector.

I'm not sure what your other Red wire in your panel would be for. Maybe C60? But I think there is a separate Red wire in the engine bay connected to the Horn Relay Buss, and it's fused there in a white fuseholder nearby.

Rich,

Here’s the double orange wire plugged into the “BAT” slot for the 4-way hazard flasher on my ‘66

Gary, Nice photo.

Rereading....
Tom's initial inquiry questions the position of the Red wire for A31. Dave's '66 had A31, and its a single wire.

Tom, or someone, please post the image of page 57 of the JG showing the double wire. I suspect it's in error.

Rich: The photo in the 1966, page 57, manual is referenced above, and copied below. It does indeed look like Gary's photo, but it's not as nice. The words "Power" and "Windows" are overexposed and cannot be seen.

So, I don't see an error, except that the sixth edition, page 57, does not mention the reason for the dual wire in the "Power" slot. Flashers are discussed at the bottom of the same page, but not in connection with the fuse box image. (pun intended.)

Tom,

That double Orange wire is for V74 Hazard Flashers, definitely not A31, which is Red.

It seems misleading if the reference is with regard to A31.

[Gary B.]

I’ve seen a ‘66 with A31 power windows with the red wire plugged into the lower LH slot in the BAT row, and I’ve seen the red wire plugged into the RH slot. Functionally it doesn’t matter since those two slots are electrically linked on the back side. From my review of the ‘66 AIM, I don’t see it mentioned where the A31 red wire inserts in the fuse block. But maybe it’s there and I’m not seeing it.

If a car has both V74 and A31, I assume the single red wire for PW would insert into the RH slot since the AIM specifies the BAT slot for V74, and the BAT letters are adjacent to the LH slot. It would nice to see the fuse block for a ‘66 with both V74 and A31.

Here’s a ‘66 with A31, Power Windows, with the red wire in the slot that I believe it was in when this car left the factory.

From my 63 with P/W and A/C.

The harness has been replaced, but the idea is the same.

Other things to check, the AIM option and wiring diagrams. It may shed some light on color and jumper wiring.
