if you have a external 4 wire ignitor and a 57b1 dizzy with a red wire and a white wire , can you check the wire clours at ecu pinouts b3 and b16 (which is directly above b3) . looking at the ecu with plugs plugged in , its the second plug , and the third wire in from the left (b3) and the one above it (b16).

the manual lists one as cas positive and one is cas negative , although its not absolutely critical on the polarity , i need to know the colours..

thanks

pretty keen to know the answer guys...

using the factory ecu its pretty critical as it uses the falling edge from the wave to ignite .

im trying to wire up a aftermarket ecu , and knowing which one is postive will save time in the config of the ecu .. eg , whether it will be rising or falling edge ignition.

the ecu pinout says that one is the positive and one is the negative , the wiring diagram doesnt show wire colours , it just shows that both wires go back to the ecu..

SV420 J20a any good to you?

[losfer]

not really , the sv420 uses a completely different setup .. it doesnt even have a dizzy ! thanks for trying though .

Sorry, but both mine have internal igniter
