- How to identify what we need, how to remove it and some other great information about the ECM/TCM harness, upper engine harness and more...
An LLY used in this example, there my be slight variations on color, but same process for the most part.
Thank you for this, I was about to spend all afternoon doing exactly what he did
This is incredible stuff, putting an Allison/LB7 into a c30 and will definitely be using your harnesses and tunes
And t case
Can you make one for the 3.0
Great information thx very much. I’ve just found your channel and subscribed. I’ve been looking for something like this. I have an 05 LLY but no harnesses at all. Planning a swap into an 81 C30 cab and chassis. 👍🏻✌🏻And HAPPY NEW YEAR, to you and your family’s
I need a lb7 wire harness if you got one
I need the harness for my Duramax LBZ
I’m considering doing a Lbz conversion in my H2 hummer. Is there anyway to get info to the bcm so the gauges work and the electronic transfer case?
I need the some ecm connections inna bad way just the part that clips to the ecm
Can I run a LBZ ECM and TCM harness onto a LLY my batteries got wired wrong and burned up my fuse box and harness but I have a lbz as a doner
I’m doing a duramax LBZ engine swap into a suburban 2500 can you help me located the black/grey wire from the ecm? Not sure where it’s located thanks for any help
So after the modification. The ecm needs a flash? What about the pass security b.s?
I just need my ECM/TCM harness cleaned up an fixed I found a couple cut wires
I have chevy Silverado lmm duramax, egr delete, aftermarket exhaust, lift pump without factory fuel filter, i think to do glow plugs delete kit im living in warm country, i just hate all the not used connectors and that mess, wan to organise and do some cleaning in the engine bey
What do you think can i delete except from what i writing to you?
And its ok to delete wiring from the ECM? I have efi live on my truck
We recommend that only people very experienced with this type of wiring make modifications to a harness. If your truck was tuned after all of these upgrades were done, your tuning should account for all of that and be fine. The items that aren't being used on your upper engine harness would be disconnected at this point and aren't needed if you aren't having any codes throwing a check engine light. We offer an upper engine cleanup service on our site. You could explain what you'd like removed and we could handle it. You wouldn't be deleting any wires to the ECM connector, because the ECM harness is separate from what you're talking about.
Hey man! Looking at doing a duramax swap on a 94 gmc sierra k2500hd with the 6.5 in it. Any way i can make the obd2 port function for tuning? While keeping it somewhat simple and clean looking
So after I do all this it should start
After you purchase and receive the standalone harness and tuned module(s) the electrical/programming part will be complete. You will still need to supply power, a switch to control it, proper fuel etc... for it to start.
Does that harness have the throttle pedal sensor attached?
Here’s what we really need! I have an LLY with the plug connector that broke. I cannot find them online and don’t think the dealer sells them either. I need a company that makes these new so I can install a new plug and wires to my ECM. This has been a real headache for me. About to hit the salvage yards tomorrow but I really want to start replacing old with new on wiring on plugs. If you happen to know anyone h to at makes them please let me know. Thanks, Matt
What plugs you need I have an old harness
@@cesarmolina2625 Hey thanks bud! I needed the plugs that plug into the ECM, TCM. Let me know and I will shoot a few bucks your way if you have some
has a Duramax with compushift. struggling to get the speedometer to work. has now coupled to 20 and 21 on bcm. but nothing works.
Lb7 2003
How much too clean up a wiring on lb7 duramax
Like the vibes bro
I got a question does the TCM run off the ecm
Do you make or have to mounts to install in a 05 Silverado 1500 frame ?
No, we don't support swaps into late model vehicles.
Dmax Swap but, why?
Morty my LBZ truck was a salvage title and my Avalanche is clean title and I already have 2 more other LMM duramax trucks
bikerbrego I was asking Dmax swap why they don’t perform late model swap
because its illegal epa wise. Hes covering his ass
So on my lb7 that I’ll be sending, it already has EFI LIVE, so do I send my harness by itself, or do you NEED to retune my already tuned modules?
You will need tuning for it to start, plus we also specialize in these types of custom calibration for your swap since a regular truck calibration typically is not ideal for your configuration. Properly matched ECM and TCM calibration is the key to good drivability and performance in a custom vehicle.
Do you send in stock ecu and tcu for tuning or are these new stand alone modules
Yes, if customers have donor modules, they send them in for tuning.
@@dmaxswap428 can I purchase tuned ecu and tcu
@@chancecolwell3823 Yes, go to dmaxswap.com/intro and follow the ordering process. It also has a lot of information about common questions.
Make nice wire tuck kit for the lly ,, I hete all that harness on my truck
Price on something like this
All products and pricing, as well as an ordering guide, are available at dmaxswap.com
@@dmaxswap428 thanks will be needing one here soon
Can efi live be used with the stand alone
Yes, that's what we use with the tuning we offer.
It would be crazy to run a manual transmission behind a duramax in a square body suburban. You know, with the standalone harness.
It has been done and works great!
Or run the duramax and Allison in a square body crew cab, k5 blazer, or suburban.
Thanks for the info! 👍
What does standalone mean?
To put it simply, it means it has been modified to run outside of the vehicle and has the unnecessary circuits removed.
