The car is a 1983 280ZX it was a turbo efi car but it now has an F54 block with a N42 head and it’s carbed. I’d really like to hook up my gauges (none are right now) I have I think most of the plugs on my car still. https://uploads.tapatalk-cdn.com/20200129/bd722383082092cb11c47dd1ff7187b6.jpg[/img]

Firstly, lay off the toast, boy.  It makes for bad writin".

Then get a copy of an FSM and see where the gauge senders are.  You didn't say which gauges.

Well all of them ideally but I’d be ok with oil pressure and water temp

Where are the wires?  The sensors/senders are in the same spot for both engines.

You have a picture of the wrong oil sensor for a ZX engine and a thermotime switch, which is common to many engines but won't tell you coolant temperature.  That yellow wire is probably your temperature gauge wire.  What is it connected to?

The yellow wire is connected to nothing and wrong oil sender?

Find something in the vicinity of the thermotime switch with an end that looks like a sender.  It's a single terminal, not double like the thermotime.

Actually I was wrong about the oil sensor, that looks like the right one.  Find the wire that fits that terminal.  It must be there somewhere.  Download the FSM from the site and the wiring diagram will show the wire color.

I think I have the wrong oil unit but I might have the right temp plug

You're right I didn't blow up the pictures.  I knew better too.  After 78 most, or all, Z's came with a two prong sensor.  Look for a wire with a two prong plug on it.   T shaped.  You're about there...  Good luck.

I found it, totally different sending unit. How do I hook up the speedo?

Also that wasn’t the right wire for the water temp

It's probably disconnected at the transmission.  Connect it.
