I'm putting in back-up lights on the wifes 36 chevy so I know what you are going to need to do. My wife almost backed my 34 ford into a post one night because she couldn't see what she was going to "hit". After my panic attack, it was pretty funny.

Anyway, Lets just say your 34 has an after market Lokar or Genie shifter. You may already have the "reverse" switch on your gear shifter and may not be hooked up to anything. If you don't, then you can either add that capability or you will need to get an electronic gear shift indicator that attaches onto your transmission (assuming an automatic). These gear shift indicator set-ups have the capability to send a feed our to provide power to a relay to supply a feed to the back-up lights.

I have these very small quartz Halogen lights all ready to install on the chevy. They will be mounted under the car so that they really can't be seen but have enough angle to illuminate the back area for backing. Like I said in the previous paragraph, I will hook up my lead from the Gearshift reverse indication into my relay which will let me supply the correct amperage to the QH backup lights without hurting the indicator switch.

It's not complicated at all, but it just takes some good planning.
