Many thanks to mr220v and PHOENIX with the wiring.
Motec installer is loving the extension i did. In actual fact he has it so he can do the splicing.
As you can imagine since the alternator is on the other side so is some of the wiring. Rather than cut the harness im just disconnecting and rerouting new wire, power , sensing altenator. Unfortunately one wire needs to be elongated , the crank angle senor wire.
All the other auxillary wires will be split loomed into the factory wire
