Should be a switch behind the carb.

Yep, a switch on the carb, and if you were dealing with a 71 & up, it'd be on the throttle pedal.

Re: turbo 400 wire ?

I think it's called a throttle kickdown switch. The mounting varied, depending on the year, engine and carburetor. I'm putting up a pic of mine, but the bracket has been modified to fit on a Holley carb. This switch works with the vacuum modulator determines when your tranny downshifts.

Re: turbo 400 wire ?

Since you have a 69, the TH 400 "Kickdown Switch" will look like the one in the picture which is mounted to the rear stud of the carburetor on the Q-Jet.

There are only two wires hooked to the switch; a power wire and the wire from the detent switch on the transmission. The wires are yellow in the picture.

Re: turbo 400 wire ?

If you don't have the switch or bracket, the best option besides trying to find used is to replace the pedal and linkage from a 71-72. This puts the switch inside the cab and gives you a throttle cable instead of the rod linkage.

Except that you'd have to cut a section of the firewall out of the 71/72 truck in order to do that.
There's aftermarket solutions for this problem.

Most Camaro dealers sell the bracket. Dealers like Rick's First Generation, Classic Industries, D&R Classic, etc... They may even sell the solenoid plunger.
