I repalce my engine in a 1994 mercedes C280. There is a violet wire that is paired with the oil sending unit connection. what does this wire connect to.

The starter circuit uses violet wires..

What is the guage (cross-section) of the wire?

What doesn't work?

I'm not getting any fire to spark plugs. engine won't start. the wire is about a 10 gauge

The engine won't start. It seems that i am not getting any fire. I was told that this wire should be connected to the starter on the opposite side of the solenoid of the ignition wire, however there is not another connection on the starter for this wire

"The engine won't start".

Do you mean the starter doesn't operate OR that the starter does operate & the engine doesn't start?
