Two-harness system to install your Detroit Series 60 14.0L with a DDEC V ECM in a Freightliner Cascadia 2009–2016 cab. Built, crimped and pin-to-pin verified at our lab in Houston, Texas.
The DDEC V advantage: no module needed
The DDEC V speaks native J1939, the same protocol your Cascadia's bus already uses. That changes everything compared to the DDEC IV swap:
- Your factory steering-wheel buttons keep working: cruise, engine brake and resume respond right where they always did.
- No conversion box: no in-between module to buy, power or troubleshoot.
- Fewer failure points: fewer connectors and less added electronics.
- Full dash: gauges, warning lights and readings work with the factory cluster.
Important before you buy
The Freightliner Cascadia 2009–2016 never left the factory with a Series 60: it came with a DD13 or DD15. This harness exists precisely to solve that adaptation.
Confirm your configuration before paying: cab year, engine and ECM. Message us on WhatsApp and we check it with you for free.
What's included
- Engine harness: connects the DDEC V ECM to the cab bus.
- In-cab harness: links the Cascadia's factory cab to the engine's electronic controls.
- Plug & Play installation through the factory firewall opening, no cuts to the Cascadia harness. The cab stays intact and the process is reversible.
- Labeled terminals and connectors, basic instructions, quality inspection certificate (QC pass) and reinforced packaging (15" × 11" × 3.25").

FAQ
My engine is a 12.7L DDEC IV. Will this harness work?
No. The 12.7L DDEC IV doesn't speak native J1939 and needs a different integration: go to the 12.7L DDEC IV harness.
Do I have to cut or modify my Cascadia?
No. It uses the factory firewall opening and never cuts the factory harness. The install is reversible.
Do I need to buy a communication module?
No. The DDEC V speaks the same protocol as the Cascadia bus, so the steering-wheel buttons work with no box in between.
Is it a factory harness?
There is no factory harness for this swap, because the Cascadia never came with a Series 60. It's an integration harness designed and built by CTS for that combination.
What if my cab is a New Cascadia 2017 or newer?
This harness is for the Cascadia 2009–2016. Newer cabs need a different integration: message us on WhatsApp and we'll tell you what you need.
What if it arrives defective?
Let us know within 48 hours with photos and the serial number, and we replace it at no cost.
Built by CTS in Houston, Texas. CTS is a diesel electronics lab: we build harnesses and bench cables, program ECMs and teach at CTS Academy.
Works or we swap it: 30 days when CTS is at fault (exchange, not refund) + 12 months against manufacturing defects. CTS is an independent manufacturer; Detroit Diesel, Freightliner and Cummins are mentioned only to show compatibility.
