I fitted a 1.6 cav engine into my nova 1.2 but i have came across a problem with the distributor wires the nova doesnt ave plugs for the coil,module or the distributor but on the cav the wires for the dizzy and a single wire for the module run into a black box located on the bulkhead,Does anyone know how to wire it or by pass this black box.

I also got told that you can change the distributor ends where they conect to the cam is this true?

Any help would be great,Coz im getting desparate now.
