12v and a pulsed negative, from the IDM circuit. Its a stand alone system. Once there is a pip signal, the TFI will still fire the coil. Look at the TFI wiring diagram. I think is the 5th wire down that pulses the coil.

Its a simple hookup.

just a brain fart lol it makes sense now. it is going from the tfi to the coil, making the coil on off on offf. so I power the + side on the coil and the terminal 3rd from bottom on tfi to 12v key on power?. I just use the same source correct? it made sense at first but then got me thinking. Im overthinking it as usual. this is for the falcon and just want it right

12V, ignition on. "Key on" will die while cranking. There are a few ways to do this. The easiest would be to trigger a relay with the factory coil positive wire. The relay would ensure that the coil and module had plenty of power.

part of the problem is I dont think he has the complete engine harness. so I can fire those to curcuits off the factory coil feed then right?

Yes. I would still use a relay. 60s wiring wasn't known for being the best.

Hey All,

It's been a while since I worked with my car and in part was because I coverted to carb and had a pos HEI distributor that never worked  .  I read this and tried the TFI and finally the car started like a champ.

Thanks for posting articles like this!

I know this an old thread, but can someone who's done this give me a little more guidance on how to properly wire this using an MSD 6AL box. It'd be greatly appreciated!

On MSD, its the white wire instead of the green wire on a Mallory.

I see the original diagram is missing now. Bottom three wires: switched 12V+, ignition coil negative (to MSD white), and 12V-.

Keep in mind that the switched 12V+ source for the distributor and MSD box needs to be "ignition switched", not "accessory switched". Otherwise, they won't get power during cranking.

I have another question for you guys. I'm wanting to eventually ditch the carb and go with FiTech fuel injection. The instructions say you have to use a 2 wire distributor in order to utilize the timing control function of the unit. Can the tfi distributor be made to work in this application?

If I read the instructions correctly, their timing control function will only work with a magnetic pickup such as a Duraspark or MSD.
