I am doing a magneti marelli efi to carburetor conversion on my 1998 Harley Road Glide. I am attempting to installed the Crain Hi-4 ignition and I need some help on connecting the single fire coil to the wiring harness.


I have a service manual on order, just ready to get my bike back on the road.


Just need to figure out what wire I need to use to send power to the coil.

 

Looking at my SM I believe it is the pink, and W/BK wires.

 

Not sure if it matters in your instance, but you might also have to change out some charging system components to. According to HD efi and carbed bikes use different parts (stator and voltage reg). I can attest, the carb'ed parts will not work with an EFI bike because i ran into that over the weekend. SO you may need to change those out as well....But I am not 100% sure in your instance, but might be worth looking into.

 

Thanks is that pink w/BK wire on the EFI harness? or is that on the main harness?

 

No need to change any of the charging stuff. I have done this to my '98 Ultra. I can't remember which wire it is, if no one answers today, I'll look at my notes tonight and post it up.

 

I thought you had to change out the EFI Ignition Harness if you are converting to carb. The SM shows that the carbed ignition harness plugging into the main harness, and the PK and W/BK going to the coil.

Also you are changing out the cam position sensor, and cup to a carbed version aren't you?

 

You can leave the pickup sensor, but you must replace the cup with a carb version.

Griz

 

I already replaced the cup and I am using the Crain hi 4 sendor in the nose cone.

I need to know if I can reuse the EFI harness or just connected the coil to the main harness.

 

According to the online parts manual EFI and Carbed bikes used the same parts for rotor, stator and regulator.

The main problem you had was you bought a cheap aftermarket charging system instead of something that is worthwhile.

 

**** can the EFI harness and the 5 pounds of junk that goes with it.

White with black tracer is under the right side of your fuel tank and is controlled by the handle bar kill switch. This white with black tracer connector is considered the carb wire harness connector. Pink wire is for the tach and located at the rear of the fuel tank.

The Evo touring carb wire harness is obsolete, seen a couple on Ebay but priced like they are obsolete. The 2002 carb harness is more readily available but needs some altering done. If you are wanting to do some pioneering and can handle wiring, you can power your Crane module with the white/black tracer, use the same coil which is a single fire, remove the 3 wires from the EFI harness, connect them to the Crane coil output of the module. Coil works off 1 constant 12 v power and the module sends grounds to fire the coil.

The Ultima 2000I kit supplies the wire harness to do this and just use the white/black tracer as your power. If you use the Evo or 2002 harness it still plugs into the same white/black tracer under the right side of the fuel tank
