i had black death on my 02 merc ml 270 cdi,ive cleaned it and replaced injector seats and injector bolts,but forgot to number 1 - 5 so ive put them in any order,it starts and runs like a bag of marbles .the Q is ,do the injectors have to be in a certain order and the colour code wires to the injectors do you know which coulors go to which one ? or is it simply connect to a diagnostic? thankyou

I know on some models modern injectors have a code no. imprinted onto them and have to be coded into the correct cylinder using the correct computer, yours being an older model not sure but good luck anyway.
