I recently bought a pioneer headunit for my 76 Blazer and all other wires are connected except a yellow wire. It saids to connect to "constant 12v supply terminal" and in the instructions it saids not to connect to battery. were should i hook it up to?

The wire colors are standardized. The yellow wire always goes to 12v constant. Going to the battery is one way of getting it, but I would go to a place inside the vehicle if possible. Either way, make sure you are using a fuse.

yellow wire is for retaining the memory on your unit. wire it up where ever its easy access. don't forget the fuse ................
