ELECTRONIC DISTRIBUTOR WIRING
HOW TO CHANGE FROM A BALLAST COIL SYSTEM TO A STRAIGHT 12V COIL and complete new ELECTRONIC DISTRIBUTOR .
..............
Stage 1 ;
IGNITION SETUP WITH BALLAST COIL AND STANDARD 45D DISTRIBUTOR BEFORE MODIFICATION .
{ 1A } Remove the wire coming from the distributor at the NEGATIVE { - } side of the coil { Marked { A } on above drawing } and keep it handy to re- attach to new coil if required.
{1B }
Remove the wires going to the POSITIVE { + } side of the coil { Marked { B } on above drawing } and tape/blank them up so that the live ends cannot touch anything .
Now tie them up out of the way
................
Stage 2 ;
Remove coil and replace with a High performance straight 12v coil .

..................
Stage 3 ;
Make a new feed wire with a SINGLE FEMALE on one end , which will attach to the POSITIVE { + } side of the coil , and a PIGGYBACK CONNECTOR * on the other side of the wire which will attach to the Fusebox .
{* A PIGGYBACK CONNECTOR is just a name for a connector to which you can attach another wire . This means that you can supply/receive power to 2 wires from the one terminal }
Piggyback connectors are available from many companies including ;

The connectors are shown on the Non Insulated Terminals page at the following May 2013 link ;

.............
Alternatively you can use Stationary Blades on the fusebox as per ;
SBC 2 into 1 terminals

If using stationary blades then you just put a single female spade on each end of the new wire instead of the piggyback shown in the photo above
...............
Stage 4 ;
At the bottom of the fusebox REMOVE the WHITE WIRE where the Yellow line is touching at POSITION 1
Attach the piggyback end of your new wire to the terminal where the white wire was .
.
................
Stage 5 ;
Now attach the original WHITE WIRE to the piggyback connector you have just connected to the fusebox .
.............
Stage 6 ;
Attach the SINGLE FEMALE end of your new wire to the POSITIVE { + } side of the coil
.............
Stage 7 ;
Attach the RED wire coming from the new ELECTRONIC distributor to the POSITIVE { + } side of the coil
...........
Stage 8 ;
Attach the BLACK wire coming from the new ELECTRONIC distributor to the NEGATIVE { - } side of the coil
...........
Stage 9 ;
PHOTO OF HOW THE FINISHED WIRING SHOULD LOOK .
MAKE SURE THAT THERE IS NO POWER TO THE COIL WHEN THE IGNITION IS SWITCHED OFF
..............
Stage 10 ;
Make a copy of your new wire and carry it as a spare .
..............................................................................
You have now bypassed the ballast system and you now know that the power is coming direct from the battery via the ignition switch .
................
NOTE ;
If you wish to return to the original ballast setup it is very simple .
Since everything is visible and easily got at , it is just a case of ;
{ 1 } Removing the new wire ;
{ 2 } Reconnecting the original white power wire to the fusebox ;
{ 3 } Disconnecting the new wire from the distributor at the negative { -} side of the coil ;
{ 4 } Replacing the standard 12v coil with a ballast coil ;
{ 5 } Removing the tape from the original power wires from the harness
{ 6 } Reconnecting from the original power wires from the harness to the Positive { + } side of the ballast coil ;
{ 7 } Reconnecting the original wire from the distributor at the negative { -} side of the coil .
