On my '68 AMX, which uses a bell crank and rod arrangement for the accelerator linkage, there is a switch mounted on the firewall bracket. It appears that the plunger is depressed at near full throttle by a tab. Two leads to it. What is it for? My first guess is something with transmission kickdown, but with no manual yet I am shooting in the dark. Thanks, Jerry Phillips Las Vegas '68 AMX 390
