'70 911t engine swap to 83 3.0 (no brain)

The "no brain" was in regards to the mechanical injection system, but could also refer to myself on occasion.
Here's the deal: I bought a 83 sc motor to put in my '70 T. I was wondering if anyone had any recommendations regarding a "clean" way to hook up the oil lines from the engine. A friend has a nice s/s braided line for oil return, but I am going to need a front oil cooler. Any ideas?
Also, a little help with the electrics would be greatly appreciated. I have looked at the books, but they can be a little confusing at times.
It has an earlier injection system with out a brain, so it's just matching up wired.
Also, What would be a good way to run a gas return line to the fuel tank (with safety in mind).
The engine came with the cdi unit, fuel pump, and accumulator. Thanks Ed
