deQuincey, you are good, seems like you have assembled a couple of these before
What is a Tz box what does this do?
If I change to a newer type motor like a 1984 3.5 m30B34 fuel injection would this unit still be used?

Now "item 4" I am assuming this has something to do with lights!!
Air conditioner compressor relay located below coil on fender
Dang, I am late to the game. It seems only numbers 4, 5 and 7 are unidentified.
Number 4 is the relay for the a/c condenser fan; it mounts on the right fender below the coil.
Number 5 is part of the vacuum control system for the carbs. I think it is called a speed switch. You won't need it if you change the motor.
Number 7 is the switch for the light in the trunk.
Markos -- my a/c relays are just as pictured here. The square one, item number 1 is mounted immediately below the fuse block. The round one with the tabs is mounted to the right front fender below the ignition coil (or at least it was until I changed it).
guys, lets not fight about this!
Tony has a 71 2800cs, I checked mine and number 1 and 4 are basic 4 prong relays and both are for a/c.
number 1 is located under fuse box and number 4 is located under the Ignition coil so everybody is right, however number 7 is for hand brake light for sure!
