Stock 5.0 motor.

Does the TFI module do any conditioning to the signal from the distributor? If I were running the coil off the module I know it is needed. But if I'm only using the distributor for its hall effect pickup, do I need the module in there at all?

Reason I ask is I have a 94 mustang motor that didn't come with the remote mounted tfi module or heat sink, but I do have a CD ignition and matching coil I can use.

Thanks!

Take a look at the manual here - http://www.megamanual.com/ms2/msd6a.htm. All your questions should be answered - unless you come up with some more ...

Thanks Don. I have read up on all the connections necessary when the TFI module is present in the system. The 94-95 mustangs had remotely mounted TFI modules which were fed the square wave signal from the pick up in the distributor. Since I'm not using the module to fire a coil, I'm wondering if the module does any conditioning to the PIP signal from the pickup?

Here's a diagram of the 94-95 dizzy connector in a TFI setup:


An here's what you'd connect from the TFI when running an aftermarket ignition:



I guess another question would be. If I just connect PIN 4 off the distributor connector (PIP to TFI) to input pin 24 on ms2, will it fry anything?

Ok, so I wired the input circuit as a standard hall effect sensor with 12v supply: http://www.msextra.com/doc/ms2extra/MS2 ... n.htm#hall

We'll see if the TFI distributor's (without TFI module) square wave output can be picked up by the MS box!

Output was wired for a standard MSD box (I'm using a Crane HI-6 instead). http://www.msextra.com/doc/ms2extra/MS2 ... on.htm#msd

Not exactly sure how long before I'll have everything swapped into the Volvo to test this setup out, but I'll post back results when I do.
