What sensors on the motor do you hook these up to? I am kinda confused on the 4 banger engines. thanks

Electric or mechanical gauges? You will most likely have to get adapters for the block as it is a BSP ( British Standard Pipe). I ordered mine from my gauge manufacturer for just a few bucks.

Since the Zuks didn't ship with an oil pressure gauge, I'm going to assume you're installing an after-market set, in which case you hook them up to the sensors they came with, using the instructions that they came with.
Aftermarket gauges can be separated into two types - mechanical & electrical ...
Electrical gauges have a wire that connects the gauge sender to the gauge itself, and unless you're extremely lucky, or you know what to buy (and if you did, you wouldn't be asking this question), the factory sender will not work with the after market gauge.
Mechanical gauges use some sort of physical (ie non electrical) method to connect the gauge to the engine - an oil pressure gauge for example, will use a tube (typically 1/8") to connect the gauge to the oil galley - so there is no separate sender, just a plumbing fitting to connect the line, a temperature gauge will have a capillary line with a bulb on the end, permanently attached to the gauge (you can detach it, but, if you do that, expect to have to buy a new gauge when you're done).
On the four bangers the factory oil pressure sender is a simple switch somewhere near to the oil filter - it turns a light on/off and cannot be used with a gauge - the factory temp sender is an electrical sender usually somewhere near to the thermostat housing - if you had told us which of the four bangers you have I could be more specific, but it varies from on the intake manifold, to tucked away between the block and the firewall, completely out of sight.

Yup I had the same trouble. A pipe and tubing specialty place in town was blown away that a Suzuki engine had British threads.
From the tubing place, I got a threaded adapter, from the BSP thread to an A/N thread...then they crimped a stainless steel braided line with the A/N fitting on one side, and another thread on the other. I used a standard 1/8" pipe tee so I was able to retain the OEM "idiot light" oil pressure sensor, as well as provide a fitting for my (mechanical) oil pressure gauge line. Mounted it remotely on the driver's fender/strut mount area, and extended the wire for the OE sensor.
I did this last July (2009) and I have no problems with the lines or fittings.

I posted pictures on the second page of the parts I ended up using.
