The 120 drops us into over-termination territory and the 360 puts us at 55 ohms and 69 respectively. Still slightly out of spec, but within margins. I don't expect 69 ohms to matter much since that is coming from the comma power. The 55 ohms is what we care about.

Yeah, something in the lightning modules causes a stub with the comma connected. You can see it when you compare an ICE F-150 to the lightning. My truck: Alans ICE F-150: The pins don't match their designations since Alan got a reversed set. But you can see one of the 128 readings is...

Man, If I knew all I had to do was make suggestions to fix the issue... Idk, I don't get that train of thought. I don't even claim credit for the final product, my goal was to understand the issue and turn the resolution into something the average person can do. It would have taken me much...

Possibly, but $200 is kind of laughable even if they accept a hardware solution. I plan on turning it in regardless once I get what i've put into it back. This wasn't really about the money for me, I am happy to produce a solution I can be proud of more than anything.

IF I can sell enough of the production couplers, I can work on designing a version that connects directly to the comma box more cleanly. I am already out of pocket about $1200 for the current project, but I have a small margin built into the end of this batch to fund any further development.

In general: This is what I am using in mine at the moment to make the breakout work and not worry about breaking the cheap connectors on the breakouts. (I will admit I am not super happy with using two additional connections, but it works well enough for testing purposes). Comma Harness box to...

Theoretically, moving to b2-b3 should allow this since b2/b3 will become equal to a10/a11 in that orientation. I would use your second breakout board over reworking your existing one in case you run into a fit issue.

Yeah, the final version is female to female. So you will need an additional cable regardless if you decide to get one when they are available (and want to install near the IPMA). You can also force offroad mode so you can change settings with the truck on.

One of the other reasons I wasn't being too forward with the information. It adds more complexity to a temporary solution.

Yeah, that was an additional benefit of moving to the 360 ohm. Since it is essentially being used to tune the canbus' resistance to stop the reflections, it can be added pretty much anywhere on the line. The trouble with the breakout box is that you have limited space in the kick panel, so it...

Just know you will need additional adapters to make the breakout work connected directly to the comma harness box. You may be able to get away without adding anything if you don't use the comma power, just be mindful of how much strain you are putting on the USB C connectors. I have been...

Intended to be heavily implied. If you have the 360 ohm version of the breakout board, it can be installed directly to the comma box. The 120 versions need to stay up near the comma unit. Unfortunately didn't have the foresight at the time to version the box's in an easily discernable way...

I had USB port shaped burns on my fingertips for awhile after removing connectors for testing. I have just been throwing away the resistors I have used for testing to avoid having to will them to my kids.

Alright – a couple of updates before I forget: I'm cutting off orders for breakout boards starting today. PCBWay has sent me photos confirming the production boards were produced correctly, which means they'll ship in the next couple of days. I’d rather ya'll get the proper design instead of...

I did. For some reason I'm dyslexic only when it comes to those two Acronyms. Corrected it so it doesn't cause confusion.

Sorry guys, I honestly didn't think so many people were making their own. I had two people contact me today and yesterday so wanted to post the updated parts.

If you ordered from Amazon, i would just return them and get the 360s personally. But if you dont mind putting the 120s in series, it will work as well. The final design was switched to the 360.

The previous design utilized 120Ω resistors, which are still fully functional. But, after further testing, I opted to switch to the 360Ω resistor. This better balances the total termination resistance across the system without adding an additional termination point, helping to keep the CAN bus...

Also, here is a 3D generated image of the final adapter to give you guys an idea of what you are ordering once available. Orientation will be marked on the casing.

New BOM for those that are building your own breakouts. 1x - https://a.co/d/243xVLD 1x - https://a.co/d/1fZUaej Install a single resistor between a10/a11. Your board will be uni-directional, the rule of thumb is to put the "A" side towards the IPMA, but I have gotten a set with the connectors...
