Additional immobiliser wiring help

[b21playa]

Hi all

Recently purchased a w205 c-class and with the amount of car theft at the moment was thinking of fitting an additional passive transponder immobiliser just so the car can't be taken by key cloning.

The unit in question, a Toad Sterling Excel seems to fit the bill for what I need and only has a few wires that need splicing; Start motor & fuel pump along with a permentant 12v, grounds, and an ignition/switch feed.

Does anyone had wiring diagrams as to where I could locate these wires?

Many thanks in advance.

I wouldn’t bother with the fuel pump, just the starter circuit, you will have to trace the wires from the ignition switch and hide the unit behind the dash after soldering and shrink wrapping the wires.
