Hot Rods Test run--wiring

Building a 39 Dodge pickup. I've got the 360/727 all mounted and I'd like to test run it before I go further. The donor is a 76 with electronic dist. w/2 wire plug and regular external coil. Problem is that I didnt get any other harness or any wiring with it. I'm going to intall an aftermarket hot rod harness anyway. But in the meantime, I want to test fire it. Can anyone tell me how to wire it to run just for a test session? Thanks,Rich
