Charlescrown thanks for your help.

How many wires come out of the Magna distributors you recommend?

The one in the car now is a early Magna distributor with only two wires coming out of it.

How do you connect this to the pulsar wiring loom that has 6 wires on the diagram?

Do you not use some wires on the pulsar wiring loom or do you combine some wires?

Sorry to be a pain, but I want to understand.


I have an ignition map somewhere so that’s easy.

How do you connect the ecu to your computer for tuning? Do you have to modify the ecu to include another connection or use the diagnostic plug?

The pickup coil is connected to the Camira module as shown. It just uses the low level ac signal to do the switching. You can also use a Bosch HE coil and module.
The polarity of the 2 wires is important and you will find out quickly if you have it wired incorrect as the engine will run like the proverbial bag.
Either the Sigma/Magna 2 wire or a later HIE will do the job.

Excellent, thanks for your help. I think I understand now.
