63 vs 64 to 67 Power Window Harness

[Harry S.]

The 63 P/W harness in part number 2981298. Looks like the 64 to 67 is 2986102. But M&H has a harness for 63, one for 64 and one for 65 & 66.

I've looked at the doc. that I have and can't find a difference.

Anyone know the differences.

Thanks

Harry, I don't have the details, but I'd surmise that the wire colors and "connectorage" may be different between 3,4,5,6. I'd have to go through each wiring diagram to see diffs. I would, but I'm heading away from the laptop for a bit to the shop to look up some circuitry diagrams on a C6 Auto-Dimming Mirror!(LOL)

1967, as we know, is a different harness wiring configuration because it requires either IGN on or ACC on to function, as there is a relay in the circuit to provide power to the window motors.

Actually, I just remembered something.....

THERE ARE NO GM POWER WINDOW WIRING DIAGRAMS FOR CORVETTE ANYWHERE?

Sorry, not yelling..... just "explativing".....lol.

So the vendors must have secret GM prints and not sharing with the world. That's ok, I've made a few of my own. Like this one for the '67's, from the Passenger car diagrams.

Of course, no back windows on 4 doors Corvette were ever allowed, so just ignore those on this diagram.
