Hi All I am a newbie on this sight.
I have a GT3 RX3 I need tech help with, I was running a Dual Distributor bridgeport 12a and have just installed a single distributor bridgeport 12a. My old ignition system consistited of a dual dist. run with Crane xr700 ignitions with optical pickups, the leading dist also had a MSD6AL on it. The new engine has a stock distributor with stock mazda ignitors, but I have no connector plugs for the ignitors. How do I hook this thing up? Do I need to obtain stock ignitor connectors to connect to the coils? Does the stock distributor connect the same way the crane units did?
Some one help!

 

You might want to post this in the 1st gen section. Lots of ignition know how in there.

 

This system is the simplest and most reliable of all 1st gen ignition systems; I use it on my peripheral port road racer.
From your ignition switch, connect 12 v + to the + side of each coil.
Then, run a pair of wires from each coil to each Mazda igniter. I prefer to use shielded wires for this run, to ensure no false signals picked up from the plug wires.
This provides the +12 volts needed to run the circuitry inside each igniter, and the other wire going from the minus side of the igniter to the - side of the coil will tell the coil when to fire.
