No wires to drag through the firewall just across the dash.

Download the 86 wiring diagram. It'll show the position of the circuit 30 wire on the instrument cluster plug. It's in one of the corners of the plug.

When you're ready to use the dash again solder the wire back together.

Thanks . I can’t believe it but monkeying around with the wires and it’s working again first pic left tank second is right . I know the right is full as I just filled it . Left has a couple of days would need to look at miles but half would be about right

Well that didnt last long . Turned it off and restarted about 20 minutes later and its sitting at 1/2 tank LH or RH

But the ac is working well
