So, I have a simple need. I have a switch in my dash that is momentary contact. I need that switch to apply power to a wire to open a motor for 0-10 seconds and then drop the power off. Then when I push the same button again, I need to apply power to a different wire to spin the motor closed for 0-10 seconds and drop the power off. I want that time to be adjustable. The other item is, when the motor is open, I'd like to send a signal back to the switch to turn its led indicator light on. Hopefully I'm explaining this correctly? System in 12vdc, if that matters? Anyone know a relay or set of relays to make this happen?? Thanks in advance
I need a timed switch for 12VDC motor.

Many members have questions. It would be helpful if you used a more descriptive title for your posts.
Your terminology seems odd. What do open and close mean in your context? Are you talking about a motor that spins in both directions depending on power polarity?

Its a 12vdc exhuast cut out motor that opens a valve, and closes a valve. And yes spins in both directions
You would be better-off using 2 momentary-contact Push-Buttons with no timer,
using a single Push-Button complicates things quite a bit,
and a timer can not compensate for unexpected Valve speed, stickiness, or jamming,
but You can easily compensate by just listening to the exhaust-sound.
If You are going to be using standard "Bosch-style" Cube-Relays,
they will need to be the "5-Pin-style",
and You will only need 2 of them, plus a Fuse-Holder, and no other parts.
Actually, with more expensive "Double-Throw" Push-Buttons, (~$25.oo-pair ),
You won't even need the Relays,
just the 2 Push-Buttons, a Fuse-Holder with a 10-Amp-Fuse, and some 18ga. Lamp-Cord from a Hardware-Store,
that's the complete, bullet-proof, and much more reliable, setup.
