I am in the middle of swapping a 2002 engine in my 1990.
I want to connect the 2002 coils on with my 1990 wiring and MSI ecu.
At first, I had the idea of connecting them like they were COPs, but they don't have tach signals, which mean I need to keep my Igniter.
Here comes this idea.
-Why could I just plug them as regular coils and kept the 1.6 igniter?
I took a look at the 2002 and 1990 electrical schematic and I put my thought into a schematic
I would like to have the approval/comments of the electronic genius in there.
I think the trigger sent by the igniter should be just fine to trigger the Coils pack, just like if they were triggered by the 2002 ecu.
And this way the igniter will still send the Tach signal to the dash.
