I own an ex RAC Transit - Mk7.

is there anybody here who knows the specific wiring for the Gemel Serpi Star e255 multican2 alarm system?

I purchased the van without the main alarm unit. I sourced one online, fitted it and it doesn’t work!

It appears the manual has different coloured wiring to what is in the van.

Would like to know where the wires in the van are connected - specifically, the CANbus wires. Manual states the alarm should have black/purple and black/red wires. Van doesn’t have this!
