I was wondering where the cold start switch is at on a 87 Trans Am with a 88 Trans Am TPI 5.0 engine? Thank you

 

The cold start control is on the front of the intake, below the throttle body, in teh coolant crossover passage. The cold start valve (injector) is between the service injectors for the #5 and #7 cylinders. The 3A supply fuse is in the main fuse panel, marked "CRANK." None of these are really "switches" but I'm guessing you're asking about the timer/temperature control on the front of the intake.
