First thought is that you have the wrong switch. It should simply plug in as factory. You may have another GM switch (ie seller listed it as fits Pontiac, Buick, Olds, etc. - but does not) or one for a B-body car, but not one for your specific car.

Now I don't know about your car, but in 1968 there were a couple different ignition switches. I purchased one that was supposed to work for my Lemans, but it did not as the spades on the back of the switch were slightly different. The GTO ignition switch is different from a Lemans, but I purchased a GTO ignition switch and it plugged right up. From my understandings, my Lemans is a "Lemans Sport" with the bucket seats, center console, and manual transmission so that may have been the difference OR, it was what Pontiac had on hand at that time and they used it.

So I would be trying to locate another switch that is correct for your application by matching up the spades on the back of your ignition switch - is your car a true GTO or clone? If it is a clone, or possibly the wiring harness has been changed, ie Lemans or Tempest, it is possible you need a switch for that style of body if it is the same thing that happened to me.

Then your best bet is to get a wiring diagram. Here is a color coded diagram: https://www.classiccarwiring.com/196...iring-diagram/ or this one: 1966 Pontiac Tempest & GTO Wiring Diagram Manual 66 | eBay

Either of these should be in your tool box and should give you the info to help with your wiring.
