.... Fucked about with looms!
This was removed from a Fiesta and fitted as the customer found it to his Escort believing it to all be as it should.
The Coil pack suppressor is plugged into the Amal valve wiring/connector
Two giveaways here... Firstly the suppressor connector only has one wire to it not two and secondly one of the pins it rotated 90deg making it hard to actually push the wrong plug on oh and of course it should be over the other side of the engine bay teed off of the coil pack live too.
The loom was cut and joined (for no obvious reason) 3" from the Amal plug and the coil pack wiring has also been cut and joined with no sign of the suppressor wiring anywhere.
If you are fitting old Ford EFI management be it OFAB, OFAC or Cossie please be sure it's all correct or you will be always chasing problems.
