hello from the Hoosier state. I have had some success. I disconnected the brown wire connection on the main power wire (orange) t- connector next to the light switch (white wire). tried to get a picture (to slow to upload). anyway it fixed the dome light and the blowing heater fuses on start up. trying to find out what the brown wire connects to, might shed some light on the generator light on. with the brown wire disconnected still have dash lights, gauges,lighter,and the heater works fine.

Mikie - in case you didn't know it, we have an electronic copy of the entire 1969 Pontiac Service Manual available for you to download to your PC for free. Chapter 12 - Chassis Electrical - has the wiring schematics that I think you are looking for. Since your 1968 GTO is nearly identical to a 1969, this will do you well. The manual will refer to your car as either an A=body or a Tempest in most cases, since the Tempest was the base level car and the GTO was the highest level for Pontiac.

Just click at the top under Learn/Manuals.
