LOL becuase it reminds me of ME! You've just joined the club of figuring things out on your own.
No suspension needed. As Cees says, think about all you've learned about your car and its history and maybe a little electrics too.
Any of us who do our own work, except for the pros, have been there done that. Isn't it a relief to have figured it out, which you did.
I say well done!
