I made a PNP harness for my truck coils using a design Barton made. It's a prototype that we're working on bringing to production. The idea is you just unplug your stock coils, and use this PNP harness to plug into the GM harness that came with your junkyard truck coils. I should have it fired up this week!
Looks a bit like the plug on a NB2 coil doesn't it...
Excuse the jankiness, I just used wire I had laying around which was way too fat.
Now I just need to toss these in a sadfab bracket which should be landing on my door step shortly and I'm good to go!

Woah woah woah.
In for details. I'd be all about hitting the easy button if you can still do sequential with this.
Looks great. Looking forward to seeing how it works out for ya.

This one's set up for batch, but we're designing it to be simple to switch it to squential.
On a scale of ¯\_(ツ)_/¯ to "obviously, idiot", how important is sequential support?
Totally in for a sabfab collab!

Sequential will never be plug and play. You need extra wires from the ECU.
For a lot of builds a simple non-sequential plug and play solution would be awesome.

If I just need to source coils in order to pair it with a sadfab collab plug-n-play kit, sign me up.

FabFlow, obviously.
Doubles as advertising for BPH medication.
Re: adding wires for sequential. Would it be possible to integrate that somewhat into the harness? That way there's a base kit that does batch and a small add on that can be all seq-xy?

Yeah, I'm thinking along these lines. Having an extra pigtail add-on. We'll probably call it seq-xy pigtails, because that name is awesome.

While sequential would be good, most people won't require it and since you need to add extra wires back to the ecu it should be easy enough to splice into the PNP harness to add the 3rd and 4th trigger signals. The idea is to make a complete PNP patch harness which means sticking with batch fire ignition.

What's everyone's thoughts on adding a connection point for sequential? It'll increase costs a bit due to the extra connects required.
I can add a connector inline to keep it batch but still allow it to be disconnected to add the two extra signals for sequential. An additional connector supplied to do this and a blanking connector to keep the unused connector water tight would also have to be included.
OR...keep the design as is and people can cut the wires and add the two extra signals themselves.
