EI Wiring

Datsun Electronic Ignition distributors have two wires just like a points distributor. Connect them as follows:

• Black/White wire to 12V ignition circuit -- the POSITIVE coil connector for EI coils.
• Blue wire to NEGATIVE coil connector

CAUTION: If you are still running the stock 1200 coil, connect to the POSITIVE side of the resistor, not to the COIL POS, which won't see 12V during normal operation. If you engine will start, catch for a moment but die when you release the starter, this is likely your problem.

Stock wiring harness. Connect the dizzy wires as shown.

If you have fitted the 12V EI coil (high-energy coil), add a jumper wire as shown in red:

The A-series wiring colours mentioned are from a 1980 Sunny:

• The original white wire which connects from the negative side of the coil to the points is not used and can be removed
• The black wire from the tab on the vacuum diaphragm can also be left off. An optional condensor connects here to reduce radio interference.
• The same applies to the black wire from the positive side of the coil to the body via a capacitor (condensor).
