OK good. I am probably loosing track of this but now it seems you are using a distributor from Ecklers. You did mention Speedmaster. So why did you mention Speedmaster and where did you buy the distributor you are actually trying to use?
If the distributor is from Ecklers, that is where you get the answer about how to wire it. NOT from Speedmaster.
I have received a email from Speedmaster. They know nothing about a brown wire, their unit has red, orange and black.
JOE, if you want help...........monitor this post several times a day.
