Firstly a little bit of background...
I recently made the interesting decision to buy my dream first car, a Ford Capri Mk1. And the insurance wasn't even as crippling as I expected

So far I'm thoroughly enjoying this introduction to classic motoring, although I've hit a snag regarding the indicators.
When they are applied, the indicators stay solid amber and do not flash. After consulting several former Capri owners, I've established that the most likely fault is the flasher unit. However, despite disassembling the dash (and checking the regular locations under the bonnet), I can't find the unit.
Hopefully someone who has changed one of these themselves may be able to help me out identifying the location of the unit?
I have attached several pictures of vacant connectors within the dash - I suspect one of which may be for the flasher.
Thank you very much in advance,
Josh
