7 Pin Connector to Where?

It's tractor and you should quit your job. You are not qualified to do this.

You claim the be an engineer and yet you don't have a clue what you're doing, nor how to get the information you need to perform your job.

Why would you come to strangers and ask them to do your work for you when the information is either available or it doesn't matter?

Have you ever heard of a parts list, bill of materials, build sheet, etc?

I feel sorry for the poor fool that has to try to follow your schematic.

Ask for help there, where somebody may give you the answers.

Lord, please bless him...

You should be praying for divine intervention for yourself.

You have been given considerable help by the forum in solving your elementary problems. But, really, asking for this type of help when it is easily available with a simple search is just being helpless, with no good excuse.

Do your own work and learn something!

Electrostatic Discharge Protection

"I would like to know where I can get these type of sensors, and the price range of them. Much appreciated!

Transmission Temperature Sensor

"I looked up on the Canadian Tire website, but they did not provide me any useful "I wonder what kind of protection method we can go with, that does not cost too much money and effort"

Differential Amplifier Does Not Work As Anticipated

"Can anybody tell me why and provide me with the right solutions?"

I apologize that I asked some "dumb" questions, and I am very sorry that I offended you. I cannot promise you I won't be asking more dumb questions, but I do know what I am lack of. I appreciate in any ways how people help, and mostly, I do get what I need, either insights or simply straightforward answers. However, these types of questions are solvable and some other problems are hard to be solved. Self-realization seems to be a barrier to many people. I think after 20 years if I still have a chance to look back to these forums I created, I would be satisfied with many changes will happen to me.

I hope you can be less angry and enjoy every moment of your life. God bless you.

You confuse honesty with anger. If you recall, I have given you ample assistance in the past.

You work for a manufacturer of tractors and farm implements. One would think that you'd know what electrical accessories were in use on them now.

Unless you are inventing a new, revolutionary line of tractors and accessories, everything you will be connecting is already well known and documented.

Others here are free to assist you in any way they choose.

First of all, I won't quit my job based on other people's opinions. Secondly, I want to thank you for being completely honest with me and all your help. Things that you have shown me here I will definitely keep in mind. I just want to address that anybody could have all different types of problems depending on their knowledge and experience. Showing what others what you know can make great influence. However, the way of communicating is also critical which can reflect what kind of person you are. I don't know and I don't what to know what's going on in your life, but I think clearly you can and you deserve a better life.

You have posted 3 times worrying more about others' personal life than giving us the information we need. A Din 7 pin plug won't be any good for a trailer to tractor connection, but it would be fine for the stereo system you are installing in the tractor. If you want help specify fully your needs and stop wasting words.
