Oh ok sorry

If the original wiring is still intact, There are very few wires required to connect to the engine.

There is a wiring loom that runs across the back of the engine compartment near the left valve cover. That has these wires:
- wires running to the alternator BAT terminal and the two wire plug on the alternator (3 wires).
- start wire and fuse box power wire running down to the starter (2 wires)

There is also a power wire running to the HEI, and there may be a tach wire running to the HEI.

You also need the large (red) battery cable running from the positive battery terminal, and the black battery cable from battery negative to a ground point on the alternator bracket or engine block.

Other wires you may have:
- A/C compressor (dark green)
- temp gauge sensor (green)
- choke power wire (color?)
- A/C idle solenoid
