Any immobiliser / wiring experts?

[Paul F]

I recently had a cat 2 immobiliser installed in my mk2 Escort, and ever since the installation the battery light and oil pressure light aren't coming on at all. I've checked everything, been back to the company who told me to contact the engineer that they sent out to install it. I've done that and he can't think why it would be happening. I'm going to go back to the company tomorrow and ask them to sort it out, but was just wondering if anyone on here would know what's causing this issue?

 

Thanks in advance,

Paul

Check your engine earth strap mate.

 

Also, if he's taken an ignition feed to the alarm he may have moved something on the ignition wiring to the dash clocks
