It usually means a revision - Ford/Bosch made some small design change, (such as tweaked timing map)? But they're essentially still the same

That's one of the main fusible links One supplies 12v at the EST diagnostic/base timing mode connectors near the brake booster The other, supplies power to the fuse box

From the description, it's most likely an ignition problem Specifically, a failing hall effect sensor inside the distributor Luckily, those hall effect sensors can be purchased new The distributor has to come out, and be disassembled though Example - https://www.ebay.com.au/itm/236524819457 (however E-series hall effect plates, have the hall sensor clocked differently) You'd need one of these, instead - https://www.ebay.com.au/itm/277224475917

Swap over the reluctor/chopper wheel, base plate/sensor and the black connector block (should plug in, where the tfi goes) not much else to it MPI choppers have one larger gap, for injector sync (mpi's batch fire in two groups of 3) EST/CFI's are all equal gap's Plus the base plate with hall sensor, is clocked differently

Kilkenny Castings, make brass versions I believe?

The car's in pieces at the moment, but I can dig out the turbo, for a close look I read once, the kits used Nissan Exa turbo's or similar?

My XE wagon project, has an 80's Nissan branded turbo, on an AIT exhaust manifold, if that's helpful?

EF and EL Thermofans theory of operation.pdf EL Falcon Thermatic Fan Wiring.pdf Ford BA Falcon, Quick and Easy Modifications The Purpose of this document is to Outline wiring information for the EF/EL/AU/BA and Territory Thermo-fans. This Document describes fitting and wiring thermo-fans in their respective factory fitted format - (eg, EF fans into EF), and also how to retro-fit thermo-fans designed for different models - (eg, AU Fans into an EF). The thermo-fan wiring and relay information detailed within this document includes, but is not limited to, EFs 3 Mode (4 Relay) Fan system. ELs 2 Mode (3 Relay) Fan System. AUs 2 Mode (3 Relay) Fan System. BAs 2 Mode (3 Relay) Fan System. EFs 3 Mode (4 Relay Fan System) - Description EF/NF/DF model falcons are fitted with two electric fans controlled by four relays linked to the EEC module. During Service operations ensure that the fan is not rotated in a direction opposing normal operation as this may damage the motor. Three operating modes are used (Excluding OFF) depending on the status of the four relays (Determined by the EEC module). The different operating modes provide different cooling capabilities.

During Service operations ensure that the fan is not rotated in a direction opposing normal operation as this may damage the motor. Two operating modes are used (Excluding OFF) depending on the status of the Three relays (Determined by the EEC /Visteon Oak module). The different operating modes provide different cooling capabilities. WARNING - On BA/Territory models, the Fans may start with the ignition in any position ! It is recommended that you disconnect the earth lead on the battery, before servicing the thermo fans!

Simply put, the main difference is that the EF model thermo fans have an extra wire (Orange Colour) from the vehicle going to the fan to allow for an extra fan speed for the Right Hand Side Fan. Because of this, the right hand side fan plug for the EFs (From the fan) has 3 wires going to it (Red, White, and Black). The Right Hand side plug is the same for all models, and (From the fan) only has 2 wires going to it (Red and Black). Wiring an EF Thermo Fan to an EF This information is provided just in case the Fan plugs have been cut or removed, (habib-ed). The following chart will give you a better description of what wire goes where.

Basically the extra wire on LHS thermo fan (White colour from the fan) is connected to the other power lead (Red Colour from the fan) on the same plug. You will need to modify the plugs in order for the fans to work. One way to do this (Not pretty), is to cut the fan plugs off the ends from the vehicle side, and use Female spade connectors, plugging these directly into the fan plugs (on the fan side).

The extra orange wire on for the LHS thermo fan (goes to the White colour on an EF fan) must be connected to the other Orange Fan power lead on the same plug. This ensures that the fan is powered up regardless of the Fan speed mode required by the EEC. Additionally, you will need to modify the plugs in order for the fans to work.

The first method is by far the easiest and trouble free solution, as it does not require diagnostic mode. Testing the Thermo Fan operation - Easy method 1. Ensure that it is safe to start the engine on the vehicle to be tested. (I.E. no tools in engine bay, etc). 2. Start the engine of the vehicle. 3. For non climate control cars - Turn the Air-conditioning to MAX, and the Fan speed to MAX. 3. For auto climate control cars - Press AUTO, and set the temperature to the lowest possible setting. Once this has been carried out, the Thermo fans should be running at their High Speed setting. Testing the Thermo Fan operation - Using the EEC Diagnostic mode. 1. With the Ignition Switch Off, Connect the Engine STI Input to ground, (The STI Input is the First pin from the left, upper row, connect this to the Pin directly below it) 2. Place the gear selector into DRIVE to turn the Thermo Fans On, then Place the Transmission into NEUTRAL to stop Fan operation. For EL Falcons, repeating the Drive to Neutral operation, cycles through the various fan speeds 3. If both fans do not operate, then you may have trouble codes logged within the EEC-V memory. You must clear these codes for the Thermo fan test to work !

EL/AU/BA thermo-fans are two stage - Both Low, or both High In factory format, A/C ON, should force both fans to full speed See this thread for tech info - Also see these documents - EL Falcon Thermatic Fan Wiring.pdf EF and EL Thermofans theory of operation.pdf

Possibly a faulty wiring join, or an ECU circuit board problem? If not fixable yourself, Injectronics repair faulty ECU's

Seal kit and DIY, is what I'd do... Even purchasing tools, would likely end up cheaper

Very tough to get decent x-series suspension components anymore, IMO 555 Brand - made in Japan, was about the best in aftermarket steering parts, but hasn't been available for years? All the brands these days, are varying degrees of no good Likely, as demand just isn't there anymore? Years ago, I purchased a pair of repro Rare Spares tie rod end rubber boots, and they'd split within 1500km's! Rares did send me replacements, but I wasn't game to use them In many cases, 30-40yr old original components, are better than new aftermarket

I think most of the aftermarket arms, are aimed at the earlier models?

Hazard light switch contacts always oxidise, and do that! Same with the dash light switch It's a thing... along with factory trailer plugs, making one side indicators, flash faster than the other (x-series factory trailer plugs, have contacts with a resistor, built into the plug dust flap, for the old school resistive flasher cans to work properly, with/without a trailer connected)
