Checking connections prior to starting up after yet another flat battery, cn anyone tell me (sniggering aside please!0 which is the ecu?

Currently got bonnet up, doors open and wiring loom in passenger footwell, all i want to do is go for a play!!

Last ime i used her, she was running like a pile of poo, and someone advised i should check all loode connections, so, i have done most, but dont what to tamper with anything i am unsure (read heavy handed, and likely to break) of.

All help appreciated greatly.

ECU is the black box which is usually marked 'Lucas' and '14cux'.It is usually sited alongside,or on top of the battery at the end of it's loom.It is attached to the loom with a large rectangular multi pin connector.

Thanks for that.

Have removed and cleaned all electrical connections, and to be honest it has had one hell of a differnece to the running of the engine.
Far smoother, and seems to be faster too.

Thanks again
