I checked with a Mazda dealer and they want over $1000 for a complete
   engine harness.

   They don't sell just the connectors.

   Does anybody know where I can buy just RX8 coil connectors?

   I am making one out of a nylon block and molex round socket
   connectors but this is less than ideal.

   I am going to put the scope on the coil and check the dwell with the
   engine running.

   Try Digikey or do a google search for after market and racing car
   wiring harness suppliers.

   what search words did you use in DigiKey ?

   They have 1000's. I tried a few like "Mazda spark coil connectors."
   No luck. If they are there I have no idea where to look.

   I found some connectors for my project by thumbing through the
   catalog. chris smale


   The simple way to tap into the electronics wiring is to get a package
   of T pins or the long (2 1/2¨ or 3¨) pins with the plastic ball on
   the end. These can be inserted between the wire and the seal without
   damaging the seal. When fully inserted they contact the metal
   terminal and you can then read what is going on in operation. You
   just have to ensure the wires or pins with volts can not come in
   contact with a ground pin if that is what you have. Sometimes it is
   good to have the meter ground right on the battery. Also verify ECM
   ground is the same potential as the negative battery post. Your wife
   may have these pins in a sewing kit.

   You could also use splice terminals that crimp onto the main wire
   providing a contact.  I've seen them used to connect trailer wire
   harnesses to the vehicle lighting system.

   Good idea. I'll check it out at the local auto parts store.

   It is hard to get to the individual wires.
   It is way down in the engine compartment under a bunch
   of intake stuff and inside a wiring  sleeve.

   I might be able to use an xacto knife on the sleeve.

But you then cut through the wire insulation which opens the possibility to moisture
getting into the wiring which then opens the door to corrosion. The pin method does
not damage anything and when the pin is removed all goes back to the way it was.
You may be able to get at it at the ECM terminal block.

I'll try it dale.
