Re: 70 GTO question
Get yourself a GM service manual for the GTO. It has the electrical schematics for the whole car. I just sorted out a birdsnest butcher job in our '69 el Camino and the manual was excellent. We have the manual for our '72 Lemans Sport and it is even better than the Chevy manual for details. Even the wheel codes were listed. I picked up these books at swap meets. Most GM literature vendors seem to have copies.

Re: 70 GTO question
OK...saw something in the 70 GTO assembly manual that surprised me...a vacuum operated muffler system ! What the...did this actually get produced ? it opened the baffles in the muffler to reduce backpressure..vacuum diaphrams on each muffler !! Strange set-up.

Re: 70 GTO question
Bob,
Only a few early '70 GTO's were fitted with "Vacuum Operated Exhaust" (VOE), before GM put the "kabash" to it. The system used a "tiger button", which resembled a RAM AIR pull knob. When pulled, vacuum went to a solenoid which moved a baffle inside the muffler. The baffle directed exhaust through a lower restriction area of the muffler, which also enhanced the sound. To see the neat application for real, click the link below to watch the 1970 GTO commercial titled "The Humbler", which was also pulled by GM. The VOE and the commercial were too suggestive of racing, so GM dropped them. The Humbler Rita
