Some wires i cant figure

[bigd65]

Ok I have a coulple wires I cant figure out. They are not cut and are in plugs

1. a long black w/ wht stripe. It comes from the wire buldle behind the fuel box and has a mesh coating at the end. First I though was a ground wire, but it has power. ( maybe a seat belt warning wire ? )

2 a flat two wire plug with one Green wire and one Blue wire. These wires are kind thick

3 a more sguare plug with Purple wire and a yellow wire. Normal thinkness of wires.

Anybody have any ideas what they go to, I have studied the diagrams I have and cant seam to find them. Other than these wires nothing has been cut and I getting them straightened out. Cant figure out my temp gauge, has power coming from it and got a new sensor and hooked it up but still not working.

Im gonna try and post some pics of thses wires
