I attached 4 pictures of different wires that I can't remember what they were for. I did a lot of customizing and installed a 350 running off MSD and did away with all the polution stuff and AC/Heat.. any help would be greatly appreciated identifying what these wires are for/from. Pictures are attached to this post.

1) Interior: Under the dash behind the glove box, there is a thicker black wire with a silver plug.

2) In the engine compartment there is a group of wires coming out of the firewall underneath the brake booster/master cylinder that has 3 ends. I am holding them in my hand.. 1 is a larger black plastic clip, 1 is a single wire, and 1 is black rubber hose.

3) In the engine compartment there is a single black wire coming out of the firewall in the top / center that connects to a cylinder w/ metal bracket and ends with clip.

4) In the engine compartment there is a group of wires near the bottom of the firewall above where the engine meets the transmission, and single wire comes off that in a plastic tube. But at the end which I'm holding in my fingers is a rubber end.

Again, any help with identifying what these wires are for/from.. I'd really appreciate it!! Thanks!!!

 

#1 is the antenna wire that plugs into the back of the radio
#2 looks like your wiper connections and washer pump hose
#3 could be temperature sensor
#4 have no idea what that is
