Re-wired for a 350 small block, no existing wires for HU or no speakers at all. How would I get this to work?

power ground ignition?

Got to love the Datsun(had to sell my though)...Really not to difficult. first run the constant and the ground to the bat. Then wire a relay to your ignition switch and wire the ACC wire from the head unit to it and the relay (getting power from the bat). For the speakers just run speaker wire.

do what they said, just run your 3 wires and then your speaker wires and your done

im assuming its a 620 truck right?....there should have been factory wires for the hu, check olddatsuns.com for a wiring diagram

I wouldn't say you need a relay.. Just make sure you fuse your constant and the one you tap off of the ignition..

A relay is not totally necessary but i would just to be safe... you dont want to draw two much current from the ignition.
