Will you get Xbox Live Gold on the 360 if you put in the code on the Xbox One?

Yes you can do that. Live works across all xbox consoles as long as its the same account.

I nwver said you were stupid I said you are miss understanding the issue

The 14 day trial is not the same as the 360 restrictions

• If you have an existing paid Xbox Live Gold subscription, you can’t redeem an Xbox Live Gold trial from games or console bundles to extend your subscription period. However, you can redeem the prepaid code once your current paid subscription expires.
• Redeemable codes for Xbox Live Gold trial subscriptions are only available in select games and console bundles.
• You can’t stack redeemable codes for Xbox Live Gold trials from games or console bundles. This means that you can’t start another trial period before your current trial period has finished. However, you can purchase an Xbox Live Gold subscription and start
  that subscription at any time during the trial period.

For Xbox 360 console customers only:

• You can’t redeem backward-compatible Games with Gold with this type of Xbox Live Gold trial.
• If you sign up for a 1-month trial of an Xbox Live Gold subscription , you can redeem all Games with Gold titles (including backward-compatible Games with Gold titles). If your Gold subscription lapses, you’ll be able to keep the Xbox 360 games that came
  from Games with Gold.

For Xbox One console customers only:

• With an Xbox Live Gold 2- to 14-day trial, you can get Xbox One Games with Gold, and discounted Gold deals.
• If you don’t subscribe to Xbox Live Gold before the 2- to 14-day trial ends, you’ll lose access to all Xbox One games that came with Games with Gold until you purchase an Xbox Live Gold subscription.
• If you sign up for a 1-month trial of Xbox Live Gold, you get Xbox One and backward-compatible Games with Gold. You also get to continue enjoying the Xbox 360 games that you acquired with your Games with Gold subscription, even if your subscription lapses.

Those are the limitationa of the ttials
