Gauge cluster wiring questions!

[cowboy5683]

Hell guys..My name is CJ and I am new to the forums..I have searched and searched this site and google to try and find the proper pin placement for the gauge cluster plug-in that goes into my 1973 k20 pickup..There are a total of 18 little plugs and I have a few figured out but I really want to be sure..Plus I have a pink wire with a white stripe that I have no clue what it is for..lol..It goes to a plug that is flat, black and has four spades for hook up..The wires coming out of it are two blacks and one solid pink and the pink and white wire...My gauge cluster is a 1973 with gauges and mechanical oil gauge...I also have tach, water, fuel, and ammeter..If someone has the proper wiring diagram it would be helpful as I said before I cannot find it anywhere...Or if they just have the plug and circuit board diagram that would be awesome..Sorry to ramble so much..just trying to give ya'll the proper info the first time..thanks in advance!

Check this write-up, it talks about the different color wires and what they are for: aftermarket guage install - recessed

I'm not sure if it will help you but it may be a start.
