I plan to disconnect the battery in my car to do some electrical maintenance. Are there any electrical issues with the car I need to be aware of when disconnecting and reconnecting the battery? The only computer this thing has is for the fuel injector, but I don't want to blow anything up.

Is the proper sequence to disconnect the negative, then positive; reconnect sequence is positive, then negative?

After removing the rear seat and backrest to do some rust repair, I noticed what looks like a ground cable connected to the chassis behind the driver's seat where the bench seat normally goes. I assume that this is the ground for the fuel pump (?). The bolt looks kinda rusty so I was going to remove it, grind off the rust, apply some dielectric grease and refit.

With the battery disconnected, I also was going to replace the battery tray and hold-down hardware, wire-brush the fuses and the terminals in the fuse box and coat with dielectric grease, and install an ipd battery quick-disconnect.

Maybe working on the brick will cure some of my winter blues. :(
