As the Forum knows I replaced the ECU the ALARM BOX and the Relay box on my "F" Before trying it out,I found another fault with the wiring once this was rectified ,the car started firs turn Now it nay be ,that the ECU wasnt the real problem but Im not going to switch it back .So if anyone want my original ECU ALARM BOX and RELAY UNIT they are welcome to it for just the cost of posting it say £5 Its for a 1999 MG F Len
