The PO of my vehicle did me no favors with electrical. The wires behind the heater control panel are a total mess. So I am slowly working on solving what's what and cleaning it all up.

For a while the blower motor worked, and now its not working for me. The wires around the heater are all jumbled up, and I would love to know where a good clear resolution wiring diagram can be found, or ideas for me.

I also have been going slightly nuts trying to find the hookup for the switch for the rear defrost. They just come out of the center console, and i cannot for the life of me find where they plug in.

THank you for the help.

Not knowing the year of your Z, I just have to give you the generic answer. Download the FSM (link below).

Edit your profile and create a signature with the year of your car. It will help you get more specific answers.

Done and done. It's a 1970 240z

Look on http://www.xenons30.com/reference for the 1971 supplement. That will be about as close as you will find for a wiring diagram. It even shows you what color wires should go to which connectors.

I think the easier way to word it is where do i plug the wires from the defrost in? For the life of me, I cannot find where they plug in.

Look on page 28 of the supplement.

Nice Steve! This is much clearer than looking at the service manual schematic.

Actually, that is essentially from the FSM. You will find the same style diagrams in the 72 & 73 FSMs. Those and my 73 were my resources for the diagram of the hazard/brake/turn signal schematic I drew up on my blog.
