Sniper Stealth EFI Wiring, and Sniper Stealth

[69ChargerR/TSE]

I attached my EFI to the drivers side of the Ballast, until I find a better location. I also need a separate location for the EFI Hyperspark Ignition.

I connected my Fitech to the driver side also. I gutted the ballast and replaced resistor w 10ga wire then filled back w silicone. Have zero issues w voltage for Fitech and my HEI ignition gets full voltage at coil.

Did you connect your HEI and EFI to the same terminal? I'm worried about feedback interference.
Where did you mount your HEI MSD(?) control unit?

My HEI control is mounted to an aluminum heat sink mounted to bottom of distributor. I use a Flamethrower III round coil. My My power for the HEI comes from the passenger side of ballast. I upgraded my electrical quite a bit. Have a 140 amp alternator and a solid state voltage regulator. The only feedback interference that can be an issue w Fitech is the tach signal. It connects to the negative post on the coil. I use a metal mesh shielding over the wire with a soldered ground wire connected to the shielding. If your ignition setup has a dedicated tach output on it, it is usually ok. But I still like Faraday shielding on my tach wire.

Looking for a 12 volt source while cranking and a location to mount the CD Ignition box.

Not sure about the CDI box, but my 12 volt while cranking is from the driver side of the ballast.

Thank you, I am using the same location for my EFI.

Just connect the blue (Ign 1) and brown (ballast resistor by-pass) together to provide an ign sense (running and cranking) for the Sniper and Hyperspark. You can omit the ballast resistor altogether.
