starter relay wiring

For original type wiring: The large lug on the starter gets a wire from the battery (the smaller of the 2 wires from the battery; the big wire from the battery goes direct to the starter), plus the fusible link wire to the firewall connector.

The screw down connection goes to the solenoid lug on the starter, which is the smaller of the 2 starter lugs. This wire is a medium sized brown wire.

The wire to the angled connection should be yellow and come from the firewall connector.

If this is a manual trans car, that is all for a '67. If an auto, there should be a smaller brown wire to a 4th spade-type connection; that small brown wire goes to the Neutral Safety Switch (NSS) on the trans.
