I am putting my wiring harness back in my 66 that the PO had removed. I have three female plug with a blue/red wire attached that I don't understand where or waht to plug into it. The osborn book point to it and says instrument light but I am not sure waht wire goes into it. I also have the saem issue with a 3 female wire plug with a black/red wire. Thanks if anyone can help. I have the osborne books and the schematic but still I am unclear on these.

It is the instrument light accessory header. It is there to allow you to plug the lights from things like tachometers into so their lights function in unison with the dash lights, including the dimmer function. If you don't have any accessories then there will be empty plugs, no worries.

RonK is correct on the red/blue plug. In addition to what he said, in a stock setup, the radio light will plug into it, and if you have a clock, the clock light.

The Black/Red 3-way plug is a switched power source. The backup lights plug in there, as well as the radio power lead.
