Lucas Ignition to Alpha ECU?

[RogNeedham]

I have disconnected the Lucas electronic ignition amplifier from the car so I now have a other end of the connector under the dash.

 

Is this now redundant as I understand that the Alpha ECU (P1071 model) has everything the car needs (in case you hadn't guessed I'm crap at electrics *confused*).

 

Having followed other threads the white/black wire in the Lucas unit is for the tacho - how does this now connect 🤔

 

heeeelp

All the ignition wires are redundant now. The weber ECU has it's own feed for the Tacho, you might need a pull up resistor depending on what tacho you have, if so then ask a weber dealer for part number 9990300700 which is the bit you need.

ok....there still something missing. I have the Alpha harness from Rob G that came with his engine. As stated before I have the existing connector from the old Lucas Ignition amplifier under the dash.

 

I still need a switchable power supply. The Alpha/Webcon harness has a brown wire and a black wire which Rob states were connected to the battery.

 

....so I'm still confused as to how, when I turn the key the car will start 🤔

 

(I knew the electrics would p**s me off)
