Hi wondering if any can help

Details
Honda civic EG Car was fully stripped to bear shell resprayed shaved bay, tucked brakes, semi tucked loom dash loom changed and a b18c4 engine was refitted car starts with no problems.

The issue
Basically with the ignition switched on the cel is not illuminating I have checked the following

changed the bulb behind the cluster Nothing
Bridged the plug to see if the cel light comes on Nothing
Tried different clusters nothing

Earthed A13 on ecu Cel comes on

Any one have any idea what could be causing this & how to resolve the issue I dont want to use the car without the cel being fixed
