I would like to know what these connectors are used for.
Something NOT fitted to your car!
You might want to replace some of those ‘crappy’ blue HELLA relays.

Wow, motordude … didn’t know those blue relays had “issues”. 
Glad you caught that one for us! 
btw, when I had a problem with one of them before, I found that spaying the blades and the sockets in the base with that electrical contact cleaner usually got things working again properly. 
Did the same thing to all. Now everything work fine.
The only things I don.t have are heating seats and phone jack… They look more like sensor than connectors.
Phone jack, in a '96??? Didn’t know Jags still had those that late … Heck, I’m thinking we had cell phones by then … 
Anyway, if yours really has the built-in phone, maybe that thing in the pic is the power feed for it? 
Daytime headlights
In other words, so the headlights will come/stay on whenever the car is running?
Do you have to plug some device into those connectors?
