SN95 Distributor Conversion kit for Fox Body Mustangs

Relocated TFI with a completely OEM appearance!!!!

 Relocates your TFI Module from the distributor housing to the passenger fender.



 Requires that you purchase separately a 1994 or 1995 Mustang 5.0 distributor to use this kit.


 While not tested on anything other than a Mustang, this kit should work on any 5.0 Ford with a distributor mounted TFI.




Our SN95 Conversion kit is exactly the same as our standard Mk2 kit, the only exception being the distributor end of the PIP signal harness. Where our standard kit has three male terminals that have to be pressed into the underside of the Fox distributor, this harness has a six-pin plug that interfaces with the plug that attaches a SN95 distributor to the donor carís harness.


All of our TFI relocation kits include custom designed extruded aluminum heat sinks with just enough Arctic Silver Heat sink grease (much more effective grease that the ďwhiteĒ grease typically used) to handle the job pre applied (no need to buy a $12.00 tube just for this one job). All kits include four aluminum 1Ē spacers to locate the heat sink off the frame of your car to allow a full 360 degrees of cooling and four stainless steel self-tapping screws to mount it with. Four stainless steel cap screws and a an Allen key are included to replace the original Ford Module mounting screws which required an uncommon tool to remove (we can rent you a Ford TFI removal tool if you need one...see below). To connect the relocated TFI module to the distributor a 40Ē jumper harness with a SN95 compatible plug is included. The harness is completely RF shielded by a layer of copper RF/EMI tape with conductive adhesive. A grounding wire is wound into the RF layer to provide to ground the harness. To protect the RF layer an outer layer of vinyl tape is applied last and heat sealed to each end.


The TFI end terminates with three female spade connectors that push onto the three prongs that† stick out from the top of your TFI module and a new TFI plug. The TFI end also includes the RF ground lead with eyelet that can be grounded to any good ground source, even the bolt you hold the heat sink in place with. Both ends, as well as the individual connectors, are weather sealed with heat shrink.


We originally developed our TFI kits to help protect the TFI module from melt-down in the very hot and cramped engine bays of V8 Monster Miatas. Since offering them for sale customers have installed our TFI kits in many other distributor-mounted TFI Fords including Broncos, F-150ís, Escorts, Tauruses and Mustangs (a complete list of applications can be found below). This kit has only been tested in Fox body Mustang 5.0ís.



Donít let your TFI system fail on you at a bad time. By using this system you ensure that your TFI is getting the cool air it needs to properly function while also maintaining a completely OEM look.

Our SN95 Distributor Conversion kit allows you to swap a 1994/95 Mustang Distributor into a 1988 to 1993 Mustang 5.0 while also relocating the TFI module.

Tech Talk: OLD (left) vs. NEW (right):

Our old kits used a reclaimed Ford heat sink which mounted the module on top between the vanes. To be dissipated heat had to travel down from the bottom of the module , sideways and then up. Heat rises. With this in mind we designed our new heat sinks with an ďunderslungĒ module mount so that the moduleís heat only has to travel up (itís natural inclination) to be dissipated. As an added bonus the underslung design protects the module better against itís second biggest downfall, water. SCIENCE!!!!

Installation of the MRM SN95 conversion† kit is very easy and can be accomplished in less than an hour.:

****Disconnect your battery and remove the key from the ignition***

First, unplug your harness from the TFI module. Next, unbolt the module from the distributor (requires a TFI removal tool...weíll rent you one). Once the two small screws are removed, carefully slide the module down to release it from the stator coil in the distributor (do not pry the module outward, pull it down only!!!). If you are planning on reusing the original TFI module (not recommended-once they fry once they are usually dead), carefully clean the existing white heat sink grease off of the backing plate. The next step is to take your new or clean old TFI module and, using the original screws, mount it to the kitís heat sink. DO NOT spread out the gray heat sink grease on the heat sink. The act of tightening the module against the heat sink will spread out the grease. Once the module and heat sink are assembled find a suitable location for it. The limiting factors are the reach of the kitís extension harness (40Ē). Once a location has been found, use the included template to drill holes for the kitís mounting screws (four included, use at least 2), tap the holes with one of the screws and bolt the heat sink down with the included aluminum spacers. Ground the RF shielding wire to one of the bolts holding the heat sink or any other near-by bolt (DO NOT use one of the† screws mounting the module to the heat sink).


Remove the Fox distributorís cap and notate which cylinder the rotor is pointing toward by marking itís location† on the original distributorís plastic collar using a sharpie (itís also wise to take a quick photo of the position to for redundancy). Remove the hold down and† pull the Fox distributor from the engine. Remove the cap from your new SN95 distributor and† replicate the timing mark you made before on itís collar. Drop the SN95 distributor into the engine ensuring that the rotor lines up EXACTLY where it was in the old distributor. Replace the hold down, replace the cap, plug the PIP jump harness in, and replace your plug wires. You are done.


NOTE: While the above† method will work fine if you are careful the timing procedure can be done much more easily IF the engine can be rotated to TDC (Top Dead Center) before work begins. At TDC the rotor will be aligned with the plug wire for cylinder #1.

The following USDM Ford/Lincoln/Mercury vehicles were constructed with distributor-mounted TFI modules and can benefit from our TFI Relocation Kit. Note that some may require a bit more adaptation than others depending on the actual location of the module and length of the TFI branch of their main harnesses:

To build a Mk3 we use a donor TFI (can be non-working) as the distributor end and a new TFI plug as the TFI end. The three red plugs attach the integrated PIP harness to the relocated TFI module. The donor TFI end bolts to the distributor exactly as the OEM one did originally.
