    I did some searching…maybe a dozen times…and while I found some nice pics and saw both that my wiring challenges are not unique AND that they can be cleaned up I’m having some difficulty translating the MiGi_Wiring_Harness, CMC_VW_Assembly_Manual, and the MiGi_II_Assembly_Manual into what I see on the car. The assembly instructions are fine…but they aren’t so good for troubleshooting.

    And sometimes my eyes and hands don’t work so well either.

    Looking at the attached pics:

    Which side of the fuses are connected to the battery? The one with the yellow wires? If so…isn’t there a cleaner and easier way to make that end hot? And what are the two non-yellow wires likely to be?

    Should there be a second fuse block? One for the energized all the time and one for the energized with the ignition on?

    What does the junction box do? What purpose does it serve?

    Seems like a lot more wires than there should be…but…

    Thanks much…

    with key off take test light & check . that will tell you which circuit is hot all the time .  then take the fuses out turn key on check each end of where the fuse connects that will tell you which is supply to the circuit . also pull the supply (hot wire ) to the coil when you test with key on so you do not burn the points out . I would not trust wire color unless you made the harness .

    Boy, does that ever look familiar.  Fuse blocks and ground blocks look exactly like MY Daytona MiGi’s when I got her.  Only my wires were ALL green, and a tangled bird’s nest. I spent days and days, weeks and weeks, trying to trace circuits down.  My son ( pretty versed in VW’s ) talked me into scrapping it all and starting over.  I purchased a Painless Wiring kit from Summit Racing.  With the patient help of my son, 4 days later it was up and running, all circuits working.  The kit isn’t VW specific, but ALL the wires come out of a blade type fuse block, and each wire is colored, numbered, and labeled.  Made it “somewhat” Painless.

    Painless Wiring kit from Summit Racing

    Do you recall which kit – even generally? A quick look showed me ~70 different kits.

    It’s a Basic Custimizable Chassis Harness  P/N  #10308   .  The directions/instructions are pretty straight-forward.  Mine is a 1970 VW Bug 1600 dual port. Like you,  I researched all the  available wiring diagrams before going with the Painless Kit, and still had to refer to them a little bit on some circuits.

    Thanks!  Oddly enough, that was the same one I had in my browser window!
