89 300E Firing Order vs Plugs Sequence
 

Does anyone have a wiring diagram from spark plug to
distributor?

There is a diagram placement i found in the plastic cover
of the distributor, which has # 1 to 6 but am not sure
whether these numbers are in relation to plugs sequence
(#1 being the plug closest to the firewall, and # 6 close
to the radiator), or to the firing order 1-5-3-6-2-4.

My car runs fine but am trying to hunt for repair for some roughness at idle.

TIA

i got the answer from Mike Murrell's post.
thanks for looking!!
