Still working on my new harness and am about purchase all the Tefzel, dr-25, connectors, etc. In my harness I am incorporating a fuse and relay similar to the MaxSpark setup, as well as a Deutch connector and a sub harness for the coils in case I ever need to upgrade to IGN1a's as suggested by someone here.

I am going to have a new fuse block in the bay(factory fuse block in the cab) pulling from the starter wire and will have a fused link for the coils relay, the one issue I am not 100% on is the switched +12 wire for the relay, my best judgement would be to use the original +12v wire from the coil harness as the coils will be getting the +12v directly from the relay now. I'm assuming this is the way the MAxSpark setup is wired but wanted to be sure there's nothing I'm missing here and end up burning stuff up. Thanks.

 

Another question, I'm running shielded 2 conductor Tefzel for the Bosch knock sensor, given the option would you also run shielded crank and cam wires? I would replace the wire from the sensors all the way to the ECU as well, only downside is the extra 2 pins on my 48 pin connector, but that will still leave me with 3 extra so not a big deal.
