    I'm not 100% sold on fuel injection for my HO build. A carb will simplify things and alow me to removed alot of wiring and sensors from the car.
    What I'm wanting to know is how much can you take out wiring and sensors wise before the stock ignition stops working? I guessing the ECU controls the ignition.
    Can I leave all the stock ignition in place, gut all the sensors and stuff then put a MSD 6 system in it? I know I can use a vacuum advance distributor but I do not want that. I also know I can just set the timming and leave it there, but I do not want that ether.

    Yes.

    EDIT:
    My understanding, and I may be wrong, but the TFI module is removed when a MSD6 is installed.

    I figured, looks like I'll have to get a vacuum advance distributor.

    Thanks for the info.

    tfi is actually a good system when it works.

    I agree. But if I put a crab like a webber 38 on my car keeping the TFI system would not be the simplest thing to do.

    I have a car running a H.O and a Carb setup. I got the early TFI Module and vacuum distributor. If you are getting a system that does the advance for you I bet you could use your current distributor just as a trigger.

    Oh and I removed the whole ECU harness. I just have the body wiring, but I did have to find a wire that can power the ignition, wasn't too hard.

    For ultimate simplicity, perhaps an early UK Escort could supply a points distributor?
    Just speculation, as I am not very familiar with those cars. Some did have the CVH engine, however.

    By early TFI do you mean one that looks like this ?

    If I get this right, you removed the ECU wiring, (and the sensors?) used the older vacuum distributor with the older TFI hooked up to it? Did the tach still work? and if so how was it wired?
    Did the sift light still work?

    EDIT:
    Couldn't I just use the older vacuum distributor and tap into the pickup without the TFI?

    OK sorry I am so late! I have a 3 pin TFI instead of a 6 pin TFI installed, it is the TFI Ford used with Carbureted 1.6s I believe. I have tach working, all sensors removed, and shift light hasn't worked in years so I am unsure if that goes through the computer or not. As far as how it is wired you may have to wait a week or two for me to be out and see the car.

    The shift light is possibly just burned out. Mine was.
