Auxiliary heater to parking heater - anyone got instructions?

[T6newbie]

Hi

Did a great job of fitting my new swivel double seat today but look to have disturbed the wiring on the auxiliary heater/parking heater upgrade. ‍I fitted it ages ago and got it from car cumtec. I recall a small loom plus the multi control. Has anyone got instructions they can share so I Can trace the wiring easily?

Thanks
