Kind of a quick update this week, not from lack of hours put into the project, wiring just isn't that interesting,
Before actually starting on the chassis harness I needed to install one more bulk head connector, With the ignition box mounted behind the passenger seat I had previously installed a 6 pin DT series connector to pass the wiring through from the chassis harness in to this box,
Main feed power & ground will come from the same pass through lug as the rear steer, so that part is covered, the rest of the connections that are required for the MSD 10 box include, Mag pickup + & - from the distributor, keyed power from the ignition switch/RII, then an output to the tachometer, & a positive & negative feed wire to the coil on the engine,
It's been a long time since I had wired in a MSD 10 box, & sometime in the last few years it has been discontinued, (which is unfortunate, only one other ignition out there is more powerful & that is the MSD 44 supermag) Fortunately I still have two of these ignition boxes, with coils,
One thing I remeber was the coil feed wires were a bit heavier, probably 14 ga & used a weatherpack connector, (rated for 20 amp)
I started thinking the DT series pins might not be up to the task for this circuit,
So back to the bulkhead/passthrough plug I needed to install. I ordered a DTP series (25 amp) 4 pin bulkhead plug kit, that should work great for the two coil feed wires, ignition feed, & probably reverse lights from the shifter,
While the plug I got had a mounting flange, it was not threaded like DT 6 pin plug, not a big deal to use nuts, but I had some leftover knurled flange nuts, so the DTP bulk head plug got a couple to make installation & removal easier later on,
Next a hole was cut & fit for the plug next to the existing 6 pin connector, (oddly enough I didn't take a single pic of the interior ignition wiring yet)
So with 95%+ of the components in place, I started stringing wire,
I don't think there's much in this world that will test your patience like fighting the coil memory & constant detangling of several wires & circuits,
I would try to "back bend" & straitend each wire out as much as possible as I went, but even if it was perfectly strait after a short time the wire would try to return to it's coiled form right off the roll,
After close to 20 hours, & probably 150 zipties, I had the major portion of the harness laid in place,
For the interior wiring I have been looming everything up with a braided, chinese finger type material, I like the material for the most part, but if there are a lot of offshoots it gets hard to install, since it's not split, (the harness has to be fed through the loom)
I was originally going to wrap the main body of the chassis harness up with super 88 vinyl electrical tape, then loom what I could with the braided stuff & call it good, so the whole harness came out of the chassis & taped up, cutting each ziptie off as I went,
Once back in the chassis I really don't care for the unfinished look of the taped up portion of the harness,
So I'll be ordering some split braided loom that I can fit on there & give it a little more protection,
Where the harness was in fact loomed up turned out good,
In the above pic you can also see where this harnes feeds into the back of the box built last week,
