Tachometer wiring from a 190e 2.3 to 190d
 

Hello,
I converted a 1991 190e 2.3 from a gas to a 2.5d turbo.
My question is how do I get the tachometer wired to the 190e harness?
The tach on the 2.5d comes off of the pump on the diesel, I have that.
I've checked several sites and am not coming up with the correct wires for the 190e. Thanks for any help.
