    Anyone think this would be a helpful Tech article?

    I just finished replacing every wire on my FJ and there are some tricks I had to 'dumb luck' my way through. Topics:

    What to keep and how to tell if the switches are OK

    How to route the different groups and what you can clip & coil.

    Where do I need diodes?

    Should I replace the ignition system too?

    How to install & adjust a DUI distributer.

    If this would make for a good technical article submission, lets hear.

    I would sure appreciate it. I am a ways off from wiring yet, but my '74 40 is gonna need complete rewiring and I was thinking of going painless. I am also looking into going TBI--so trying to learn all i can about ignitions/distributors etc., before i make a final decision.
    I just finished the frame--sandblasted/por/chassis coat--still have a long way to go before wiring!
