I just got my Ultra MDI ignition and i need some help with the installation.









Where do i connect the black and the red cable?















Where do i connect the black cable?





What does this chart mean??



Let me know if you need better pics.

 

My guess would be: red goes to a fused 12 volt source(looks like a larger underhood fuse in the pics to me), and black goes to battery ground. Just my 2 cents. Another thing, I noticed it says ELD on the diagram, I believe that stands for electronic load detector, which is located in the underhood fuse block.

 

Has anybody here succesfuly installed a Ultra MDI?

 

What else could it be?? You have the signal hooked up to the dizzy right?? Coils are hooked up right?? Then all thats left is battery hookup and ground.

 

red power
black ground
and make sure you keep that gold box right side up

 

Yes I did. Red ones goes to the power in the fuse box and the black one goes to the ground.

 

Do i still need the ignitior (ICM) in the distributor? Do i have to modify the distributor in any way? Can i remove the coil and ICM from the distributor?

Is the ignition in the distributor still triggered? Does the tachometer gets it's information from the MDI?

 

The distributor has to stay and they will be no mods at all.The MDI just plug n play. The MDI also requires the reading from the original distributor if you take off the ICM and the unit will not work at all. The tach gets it's signal from the distributor through the MDI.
