Brc lpg expert required

We've hit a brick wall
It's a plug and drive ecu sf fly
I have wired the petrol injectors to the brc ecu but no signal is coming out the ecu for the petrol injectors to work. He connected the power to the ecu but again no signal coming out the ecu injectors for it to fire up on petrol
The ecu is fully working as we've swapped it from an x5 I have and works fine
Does the brc loom need to be connected to the obd socket for it to fire up on petrol only after wiring into the brc ecu or other connections to just fire up on Petrol
Sorry to trouble you but its stumped me

Sorry it's on my l322 4.4 m62 engine

Sounds like you need a BRC expert or at least factory instructions. There are a few install manuals on google

Unfortunately the distributor in the uk folded a few months ago and Tinely tech has just become the importer so im trying to get hold of folks that are no longer there and Tinely tech do such a lot and its new to them
Ive decided to go for a new emer kit with type 34 injectors and the instaler is putting it in tomorrow for me. What a carry on but im keepng the brc kit and determined to sort it out.
Thanks for your help

Give timely a bell, they are the most helpful people in the world.

No need to as they around the corner to me
It's confused us all and the loom pins out as it should so sometime it's best just to bite the bullet
It's like the l322 gearbox
Simple if your doing it every day with the same problems, but not if you put a Kia box on the bench you don't know a lot about
