I used VSS power because the foundry harness used it. I did think a bit about using power from the original igniter, but didn’t look into it too deeply, and figured there must be a reason the foundry harness used VSS power. I just wanted it to work with minimal struggle, so went with the known schematic. Def worth a shot using the OG power though.

FWIW, I messaged with foundry3 on ig today asking why he used VSS power. He said it was just convenience, and it was a design decision he made a long time ago. But it didn’t seem like there was any real reason. So not totally sure, the OG power source is probably fine. I guess I should move mine… maybe I’ll make a little patch harness to try it out. It would have been simpler to use that in the first place
Aaand looking a tiny bit deeper it seems the fat blk/yel power wire isn’t on a convenient plug in the engine bay. It looks like it comes from the fuse through the harness directly to each coil. So youd have to cut wires or make a little patch harness on each og coil plug. I think? Not 100% sure.
I guess if you wanted a more oe setup, you’d just need to get grounds to each k coil, then pass the signal wires through with a patch in place of the OE igniter.

Now it's getting serious.
I've started a wiring diagram. I think I will use the OEM plugs with small patch harnesses on each coil to go from the 2 to 3 pin plug, kinda like the RDX injector adapter plugs. And run a ground wire to each coil, terminating at the ground pins on the 8-pin plug. This will allow me to ground to the OEM loop.Do it! Curious to see how it comes out. I think the OG coil connectors use 1/4” blade terminals so should be easy to make a patch harness.
I was going to ask if anyone knew what the 2-pin connector was. Looks like a HX090, but I can't find a 2-pin version.
I took the car out for a long drive last weekend, the first time it’s really been out all year. I spend so much time fussing with it and thinking about its little issues, it was really nice to just enjoy it for a day, get a feel for it as a whole.
I went up through dry creek valley, which is obscenely pretty this time of year. The leaves changing on the vines — each grape varietal has a bit of a different color — and at 4pm, the sun is pretty low, making for a dramatic backdrop. I tried to take a couple pics at stop signs but failed to capture it with my phone, so a pro photo will have to do
Sonoma county is home to the car. If you’ve ever had a Dry Creek Zinfandel or Russian River Pinot you may notice a bit of spice. That’s the soot I sprinkle all over Sonoma county’s grapes with my rich AFR pulls. Adding to the terroir. You’re welcome!
Up past dry creek is Skaggs Springs road, 20 miles of smooth pavement, elevation change, and pretty high speed sweepers. There is usually no traffic except for motorcycles who treat it like a race track. It was the perfect place to really test out the short Quaife rack on some 50-70mph corners.
The short rack verdict is in (again): it’s awesome. It feels a lot shorter and effort is just right. The new rack has also totally, 100% eliminated the steering wheel shake I had at 65-70 mph. Double win.
I stopped to take a couple pics at an overlook at lake Sonoma.
It was dirty, though. One year’s worth of dust, and my fingerprints from opening and closing the hood 100 times. Sorry not sorry.
Dirty but fun. Days like this remind me how good the car is and how far it has come since the first drive. It feels good, sounds good, looks good. There was a moment when I was on a newly paved section of twisties, zero traffic, 6k rpm, a little sc whine, passing between redwoods and hills of red & orange vineyards, I got a little emotional. Just me and my middle-class F40 on a beautiful road with a beautiful view.

Thanks! Yeah the LMGT4s work really well on the car. They are kind of an inside thing with Nissan people, they’ll usually point at the wheels and be like “wait, are those …”
