    Default Max distance between coil & MSD 6AL-2 (6530)

    May seem like a silly question.

    Does it make any difference to the ignition system if the control box is in the cabin of the car with the coil at the very front of the engine.

    I have a 289 Windsor with EEC IV setup fitted. I am about to install a MSD dissy, coil & a 6AL-2. I don't really want any more stuff in the engine bay.
    So want to mount it in the cabin of my Hilux. Also do I need to pay any particular attention to how and were I mount the MSD box.



    Thanks Richard in Australia.

    Richard,

    Since your battery is in the engine bay, logic says to mount the module between the battery and the coil, allows the wiring to be shorter.

    You can still mount it in the cabin (glovebox etc) if you want to hide it, and gives easier hookup for programming access.

    You do have a 6530 6AL-2 programmable, or a 6421 6AL-2?

    I have a 6530.
    I have a good power suply in the cabin (13.8v) as all the fuses, relays etc for the EEC IV are just behind the glove box.
    All the wiring has been hidden. I should be able to cut the two wires for the coil (at the ECU ) join them to the MSD then join the wires from the MSD to the wires that run to the coil. I will only need to re-rout the tacho wire from the coil to the MSD tacho out put.
    Does this sound like a fair plan of attack.

    Richard,

    I would think you would use figure 9 on page 9 of your 6530 instructions.

    here is the right way to run the grounds on our ignition system.
    this way we have a "true path" to ground.
