After so many wrong cables (to include the J1708 Deerborn originally sent me) and the ones I got off Amazon that were wired VERY wrong for a DPA and the one that came with my DPA4 that is also wire differently) I just wanted to be absolutely certain before I plugged something into...

And that was likely where my assumption failed. I was looking at the 15 pin male cable end clearly shown in the documentation. And my assumption was that the J1939 end was also the cable end. And I do see the cable/receptacle clarification now (down in the Type-2 Introduction...

Except for the parts where the documentation labels the plug looks to be incorrect/mirrored. *specifically look to C & D (the CAN J1939 hi and CAN J1939 lo) *according to the document diagram (J1939 end) , C & D are not used on the male J1939 end of the cable The document is...

Appreciate it ! Thanks for taking the time.

Yeah, that's the plan. But I can't seem to confirm that the DPA4 and DPA4+ have the same pinout/cable. That's what I'm after. How is the DPA4 wired? Same as the Plus? The documentation from Deerborn indicates they are the same. But it also lists the pinouts...

Now if I can confirm the DPA4 cable pinout (not the plus) I'll have a second reader that I can pass along to someone. I'm....hesitant.....to hook it up with the cable that it came with given the alteration in the pinout. In *theory* it should be using the same pinout as the...

OK, SUCCESS for the most part ! I downloaded Deerborn's little diag tool and it confirmed that the DPA4+ was in fact talking to the CAN J1939. So this pinout is in fact correct for the DPA4+ Next was a mino settings issue with my CAT ET software. I dug down into Utilities...

If the "Deerborn" document is to be trusted (which I suspect it fully cannot): C & D (which are empty on my cable) are CAN J1939 lo and CAN J1939 high Either the doc is wrong (which I suspect) or this cable is wrong (which I doubt, but it has no part number tag from Deerborn). Just...

So yet ANOTHER $80 thrown at this on cables since nobody bit at my above request....and still cannot make heads or tails of things. I'm in $400 on this DPA stuff and beginning to think I should have just stuck with the Bluefire and looked at the pretty gauges. I ordered the above...

Cool build for what they are going to use it for. I'd have gone another route for an "overlander", myself. I doubt anyone will ever sleep in it. But it's clean looking...

OK, I had to go look at it. I remembered wrong. Under the little rubber cap is what appears to be a test light with a push buttoon. I'd never really looked at it closely before and just thought it was a two-prong port. LOL Yeah, what ever that is unscrews and behind THAT is what...

Can someone with a DPA4 or DPA4+ (or I'm guessing a DPA5) do me a quick favor? Can you match the 9 pin ((letters) to the 15 pin? I have the tech brief from Deerborn, and I now have three cables here in front of me and none of them are wired even remotely the same, and none of them...

True for those who don't address the insulation and window tint. Interestingly, I've spoken to people who have done it though. I chuckle when I see people in FB groups insisting that if you want to cool an LMYV cab you simply MUST have a 30,000btu Gen2. But they cool their entire...

Good to know. I'd have never guessed that. My M1083 ABS port has what appear to be two male pins on the trailer (I assume a ground and a data wire). It's also much smaller in diameter than the J1939. I'd have never guessed that a J1708 6-pin would work on the 2-pin ABS connector.

They vary for sure. You have to watch for shipping when looking at Ali. As well as complete "kits". Some show only the two units, some show complete kits, most of the time they will tell you it's a complete kit. But there aren't all that many of the little scroll compressors used. How...

This looks to be the same unit on Ali https://www.aliexpress.us/item/3256805713164791.html

Yeah, note that they ship from China. May as well use AliExpress and pick them up for $350-$400 ea

Yeah, it appears to be a little 24v mini split. A couple people here actually run them in the cab or hab. I haven't ordered mine yet, but I have one picked out on Ailexpress. If I'm happy with it in the cab, I'll add a second one for the hab to complement my little 5K 110v...
