engine and drivetrain What is this and can I get rid of it?

[ThisIsTheRanger]

I am wrapping up an EDIS conversion (with MSII) and am trying to get rid of the coil and related components. As far as I know, the only wire I need to keep from the bundle going to the passenger side of the engine bay is the black tach wire. This goes to the negative side of the coil and also ties into the condensor, correct? The reason I ask is there was also a black wire going to the positive side of the coil that gets very low voltage with ignition.

What is this big relay looking thing outlined in red? It was located where the red arrow is in my diagram \/ \/ \/

If the big red outlined relay looking thing isn't needed, can I just cut all the wires where the green line is?

sorry i can't answer your question, but,

why don't you merely wrap any unwanted wire in a neat bundle using cloth friction tape or common electric tape and store it neatly out of the way? the next owner of your car may thank you.

[ThisIsTheRanger]

Well the idea was to store everything I cut off. That way I can still use the wire colors to match up the wires and have the option to reinstall all of it.

You should have at least 2 wires going over there - one key-on power and one for the tach. If the car is equipped with a ballast resistor (which could be the relay looking thing you pointed out), then you should also have a wire that is hot when the engine is cranking. During cranking the ballast resistor is bypassed and full battery voltage is provided to the coil. Once the car lights up, the ballast resistor comes in to play and the voltage to the coil is reduced.

For the electronic ignition conversion you are talking about you would not need any of the ballast resistor related components or wiring. If you have already located the tach wire, you should also find the key-on power wire - this may be needed there depending on where you have things located, or it should be insulated if it is not needed in that location.

I am not going tell you what wires to cut, but the relay looking thing is the coil resistor "starting bypass relay".

The coil resistor, aka ballast resistor, looks like a ceramic block with a terminal at each end.

You certainly wont need that with the EDIS setup.

[ThisIsTheRanger]

Ok then I will just cut the wires there and insulate them making sure to keep them organized. Now the only question is if the condensor wire is the tach but I can just hook it up to EDIS and see if it works.

Thanks chaps.

Just plug and pray.

Tell us about it when it runs.

The black on - of coil is tach, + side of coil unfused +12v. actived through key switch. silver box is windshield washer bottle pump, and wiper motor. Tach wire will need both coil packs trigger from EDIS control box. All tach info should be available on fourm search.

That's not the washer pump; it's the flux capacitor.
