was reading thru an online help on the fast ez efi,, and noise interference and erractic idling was mentioned, (same as my car), says not to run the ignition wire to all parts (oops). I spliced in my ignition switch, msd box, and fast ecu to the 1 wire.. I could use a bus bar from my switch to the solenoid, then branch off to my ecu and the msd box and still be good to go? I have a mini bus-bar I will use that is kinda like this

I wll use relays if I can figure it out, thanx anyways

Rick, you might consider running a dedicated power and ground wire to the ECU from the battery. The ECU needs clean power, and the drag on the power wire from the MSD and other accessories can cause ECU problems. Also, a large capacitor between the power and ground lines right up at the ECU, will help provide a good stable voltage. MSD makes a good capacitor for their units that also works with an EFI system.

I have dedicated power and ground to the battery for both the ecu and the msd, also have the msd noise filters on both the ecu and msd., ecu on left side of car, and msd on the right, so that's all good. I wired the ecu 12v switched to the stereo wire (no radio), and msd is off the ignition wire. I did figure it all out, and the thing runs great now.
thanx
