64-66 Instrument Cluster Harness - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Anyone replace their panel harness? I just came in from trying to install some LED bulbs and it turns out I am missing like 3 or 4 wires that would have a connector on the end for a bulb. They aren't tucked away anywhere either. They just aren't there. No wonder my panel has always been a little dull at night.

So after replacing the bulbs that were there, my Tachometer gauge and temp gauge lights will not turn on anymore and they used too. Probably loosened a wire or connection when I had my hands under the dash? Anyway I will get that figured out, I ended up just switching the led bulbs back out and putting the regular bulbs back in.

So it looks like I am going to have to order a new dash harness. They run about $70 bucks and then try and swap it out for the new one. Something has always been wrong to begin with my wiring because when activating my turn signals the correct direction always worked up front but both rear brake lights have always blinked at the same time like if I had my hazards on but I never got around to fixing it.

Went the route of adding extra grounds to the tail light bezels and ran a ground wire from the battery all the way back to the end of the frame but still did not fix the issue. Someone had connected a trailer hitch harness on the end but I ended up removing it along with the hitch itself.

By the way I found a light socket that says when illuminated "Over Speed". I never knew the cluster had one. Found it by mistake when I put the turn signal socket/wire in the wrong cluster hole. So back to the harness does anyone know which one is a direct replacement for a cluster with factory gauges? My truck is a 1964 Fleetside. I have looked a few up online but they seem to have a different amount of wires with bulbs?

This one looks like it's for 11 bulbs?

And around the same cost from Chevy C10 Parts.com It has around 7 bulbs on this harness...
