I am ordering a new gauge cluster (Classic Instruments) for my C10. The OEM wiring harness plug has to be cut and re-attached with the new harness connector. Sounds easy enough... but very challenging without a wiring diagram. Does anyone know where I can get a wiring diagram related to the dash gauges for my C10? I've searched eBay and the shop manuals are going for $60 and up. Thanks!!

If it's in the Chilton book I got a used one from Amazon for like four bucks. I'll look later tonight and see if the diagram is in there

The factory service and wiring manuals are available in PDF form on this forum. Right here in the reference library forum: https://www.gmsquarebody.com/forums/the-squarebody-reference-library.52/

2nd Monday of the week! I know what you mean. Yes, the manuals listed in a thread on this site was very helpful. Thanks again!

Does anyone have the Classic Instruments or Syndicate gauges installed in their truck? I'm having second thoughts about cutting the harness plug off and wiring a new one on. I think the Syndicate are plug and play.... Any info would be greatly appreciated!
