Hello there, I'm Mara from Italy
I've recently bought a cruise control canbus aftermarket for my citroen jumper 2013 euro5.

Wiring sheet asks to cover odb2 with a cap just to get red/black power, then another red wire under fuse needs to be connected to a whiteviolet in the ecu.

Any chance to avoid cuttin ecu wires and to loose the odb2 port with a cap?

My 2012 had it fitted by rhino installs, he had to make a loom up and I assume modify/cut the original as the wiring supplied only fitted pre euro 5's or pre 2011 builds. Sorry can't offer more help, but it's still possible that the aftermarket kits have early model looms

Bridgewater Electronics, UK, were able to give me advice when installing a cruse control, they may be able to help you.

DON'T cut ECU wires! Ever!

Gently cut the insulation and remove a section to bare wire. Wrap and solder your tap wire onto it and then cover with insulation shrink wrap/ Tape.

The wiring will likely need Fused power earth and then Can hi and can lo to the canbus adapter, which will read the speed pulse (hall signal)

Not hard. What part of the country are you in? LOL! ITALY - Just noticed!

Thank you all for your kind hints!
I was wrong while I said about the ecu, I found the installation sheet and it says:

• red wire to pin 6 of ODB port
• black wire to pin 14 of ODB port
• red wire with fuse (1A) to blue/yellow wire of BCM (that's they want to cut)

For the ODB they provided a cap who probably links pins correctly but... A cap on the ODB? How to diagnose then?
I've did a short search online founding BCM stay for Body Control Module, not ecu as I said before. By the way I find weird cutting wires because the change can't reverse.
Another search said that in FIAT the odb pin 14 is +12v power and pin 6 is CanHI port. Looks like a data port.
On monday I'll bring my Jumper to a local service and I'll try to explain the situation, maybe he could help also.
