Re: 1972 C20 -Airride conversion-

@SCOTI, Thanks!

More updates,
since the exhaust was done all it needed before the bed could be fitted again was the parking brake.

So I got this little actuator controller.


This is an easy way to controll the electric actuator.
Just wire up power from the battery, power to the actuator and 2 signals for pull in and push out.
It will controll the actuator as needed, and has a current limit off mode. So when the actuator pulls 3,5 amps it stops. that way it allways pulls with the same strength. Even when the brakes wear down a little.

I wanted to keep it looking original in the cab, so I liked the idea of still using the foot pedal for the parking brake.
So I used 2 pull style switches pulled by the foot pedal.


The top big spring is just to have a little "feel" in the pedal, and for the pedal to go back when pulling the release handle.
The smaller springs are to prevent over extending the pull switches.
Top switch will be pulled when pedal gets pushed in. And will tell the controller to pull on the actuator.
When I pull on the park brake release handle the footpedal gets pulled back by the big spring, and also pulls on the bottom switch. Which is telling the controller to push the actuator out.

Pretty simple, and works like a dream.


So with the park brake working it was time to put de bed back on.
Cut out the middle reinforcement, for clearance.


Then threw it on
