What is this?
Under the dash of my -71 Corvette (270hp/aut) I found this device (see the arrow on the pic). It is located up high to the left of the steering column. It has two electrical connections, but I can't find any loose cable with a contact. The cylinder formed thing to the left of the device can be pushed and pulled.
I really appreciate your information of what it is.

I think its the auto kickdown switch, the rod should be operated (slide) by the gas pedal arm. (if it looks like this one) http://www.americanclassic.com/Googl...70NOS-1970.htm

The switch is actuated by sliding the rod (when you depress the gas pedal), hence making a contact enabling the kickdown.
I can take pictures of my 74 diagram which shows the wiring, but I don't want to give you wrong info as well as we're mixing up years here.
Yes there's wiring on the switch which goes through the firewall and then (i think) to the transmission kickdown solenoid.

Thank you, now I got it. I found the cables at the transmission and on the firewall. They are now connected.
So the only thing is to wait for the sun to shine here in Sweden so I can take my babe out for a ride.
Once again, thank you for the assistanse.

There are 3 wires from this switch.Ground/kickdown/cowl vent I beleive.
Can I isolate the cowl vent to operate manually?
I am not sure why this happened. can you shed some light on this
thanks

I have a 75 with this same kick down switch, thing is it only works at WOT...is there any kinda adjustment for this? this switch is also hooked into the cowl vent on the hood to open at the same time. The only reason I know this is that I unplugged the switch and put in a pull switch under the steering column so I could open and close the cowl vent at any time looking for outside air. Worked good in the garage but on a road trip I pulled the switch and the tach went up to 5000 rpm. .I was going about 60 mph in drive.

The only adjustment to the switch is by bending the metal bracket it mounts on. Proper adjustment is important for the TH400 kickdown.
For the cowl induction, I just removed the flap and actuator so it's open all the time. No real downside to that.
