NAV System Successfully Removed

What exactlly are you looking for?

BTW here is a link to Tokugawa's DIY: DIY - Nav System Conversion

Between what Tokugawa and I have posted in this thread and Tokugawa's DIY thread, you should have enough information to do this. This DIY is not for beginners. If you do not understand pin outs and wiring diagrams then this might not be the DIY for you. Not trying to be mean it's just this is not a plug and play DIY. If wired wrong this DIY has the potential to cause damage to the HVAC system in your 370Z.

Translation to this write up, you have to cut or splice into the harnesses a new harness that will plug in. It's not simply plug and play

I can get my ac controls to work! They don't do any thing. I brought controller and ac amp from eBay. Had to pin and wire my Own connector. I did continuity checks on the connector everything is right. Pls help😔

With out seeing your work it is hard to diagnose the issue. When scope22 was having issues he posted pics of his wiring job (in the DIY thread) and I was able to see that he had wired it incorrectly. Post some pictures of your wiring job. We might notice something that you missed. Also post a pic of the AC auto amp part number label. Same thing for the controls.

My best guess with the info you have provided is you might have a bad part. Most of the parts on eBay are salvaged from wreaked cars so buyer beware even if they claim the part to be functional. Testing the controls and AC Auto amp takes a higher level of knowledge and test equipment that most people don't have. If your wiring job is good, the only route would be to swap out the AC Auto Amp and controls with known good ones or test your parts in Non-Nav Z.

Thanks I will post pics. You can hear the ac heater go on at a slow speed with automatic climate control changes. Just can't adjust anything when you turn the knobs nothing happens. They do light up when lights go on. I had to rewire plug from scratch wondering if the resistance in the wires makes a big difference? Thanks in advance

Easy fix, the pics were very helpful.
You have the pins backwards for the control wires.

You have:
Pin 4 of M67 going to pin 6 of M66 (green)
Pin 5 of M67 going to pin 7 of M66 (white)

It should be:
Pin 5 of M67 going to pin 6 of M66
Pin 4 of M67 going to pin 7 of M66

I think you miss read the pin-outs. You wired the control TX (transmit) signal pin on one plug to the TX pin on the other. It should be TX to RX (receive) like plugging in an AV source to a head unit; the output of the source (TX) to the input of the head unit (RX).

Swap the green and white wires on one of the plugs and you should be go to go.

VABAM

That's the rear defrost. Is it actually working but the light doesn't come on or is not working at all?
