Passenger air bag light/10a fuse blowing

Having an issue. Passenger airbag light comes one when I put my truck into reverse (09 double cab) and the IGN1 fuse blows, causing the truck A/C, turn signals etc. to not work as well as once you put it in park it wont go back into gear. Doesn't do it every time but has been happening alot more lately. Any ideas where to point Toyota in cause they didnt know where to start at all either

 

If it only blows when you put it in reverse you have a short in the reverse circuit, do you have a manual or automatic?

 

Automatic.

 

That park/safety switch connector is known to give issue.
Along with the switch it’s self

Here is post I did on it awhile back.

You can basically thank @Jimmyh , I just put all his info in one easy to navigate post.

Or wait on Dm93, he’s a wizard at this electrical stuff.

 

I guess to add to the post.
When you unplug the connector, check pin #1 (Red/White wire) for a short to ground.
