Been searching around and couldn't really find an answer, so I'll ask. I've got a v8 installed in my 80 280zx base model (no power windows, ect..) and am finally getting to the wiring. I'm installing aftermarket gauges, but if I do, how do I bypass the stock ones so that the car will start and run. I remember previously with the stock motor that the car wouldn't start without the gauge cluster plugged in. I was also needing to know if the stock lighting system would still operate without the gauge cluster, will the turnsignals and what-not still function? I'm planning on making a new engine harness with an aftermarket start button while still using the stock ignition for power, accessory, ect... Any help would be appreciated.

btw, it's a carbed 350 with a 700r4 w/stall and the speedo is an electric

 

The car should start without the gauges plugged in. I have an 83 all power and it starts right up with entire dash removed. And the car should start with the multi function switch disconnected as well.(windshield wiper, blinker, light switch).

 

No clue. I bet you need to modify the stock gauge harness sense the wiring for the key is in the same system. No clue tho with the 350lb boat anchor wiring tho.
