I'll check tonight in my book. It's specific for 67 to 75 blazers and pickups. I'm hoping its on the shelf and not still in storage. But I'll let you know. If I remember right my radio and lighter power was piggybacked on the same fuse spot. What specifically are You looking for?

I want to reinstall a radio but wire it correctly this time. I do have a wire coming off of the lighter that I could use but my lighter is wired to always on power. I can't find the lighter on the diagram either so I don't know if that is correct or not.
 
My radio is direct wires to the fuse block. There is a blade plug in for acc and also direct battery power. My under dash harness was pretty bad when I got mine so I had to do it that way as a lot of the wiring was cut or spliced already and I chopped a lot of it out. I couldn't find my book so it's in storage somewhere. It looks pretty much like the diagrams I've seen on the net that you posted. You need the under dash wiring diagram though. Stock it may have been wired like I did but back then it may have had constant power so you could listen to the am stations without the keys. Like said I had my wires piggybacked in the harness from the junction block. One main wire to the lighter. Then had a plug in next to that for constant power to courtesy light in the glove box and possibly power the radio. At some point I need to do a complete rewire under my dash. That way I know it's correct and not rigged. I believe the wire coming off the lighter was a thick red wire direct wire to the fuse block cig spot and the wire powering my courtesy light was orange. I can look for sure if you need conformation. Both those wires are fused in the fuse block as cig.

Don't know if this will help any, but on my fuse box I have my stereo running off of the male port labeled radio. You can see it in my pic as the two red wires are together running off of it. The text radio can be seen below it, between the two tube fuses, and a little arrow above the "Radio" text points to that part:

That way my radio come on and off when I turn the key to on or to acc.

gotcha, thanks. I have a blade stuck into the same spot on my fuse block but didn't notice the label (or mine is worn off). I assumed the blade was a mickey mouse PO job. I didn't realize it was designed that way. :rolleyes:
 
I believe the second wire on mine is the fan blower motor...so it is probably a mickey mouse job still. But it seams to be working so far and no fires or hot wires that I know of.

I forget which wire it was, but one of them was just jammed into the side of one of the pins. PO work is fun...as I am sure many could say about some of what I have done. Hopefully not too much jerry-rigging though.

Yeah, unfortunately a lot of the mickey mouse crap I find on my truck was done by me when I knew and cared less than I do today. :rolleyes:
