My situation is the same as yours . . Replacing a 1fn engine with a 2mg engine but using the 1fn loom. I was advised to change the cdi unit to a 2mg one. Awaiting arrival as I speak. What was the outcome with yours. Have you got it running and what did you have to change?

Never heard of a 2me, sure it's not a 2mg?
Oxygeneuk, I think it's me (and the anoldmanreturns) that was talking to you about the 2MG swap. Was it on facebook?

I've had so many comments that my brain is mushed. Some say just use the 2mg cdi and existing 1fn loom. . .some say use 2mg cdi and loom. Others say coils are NOT compatible..others say they are. Totally lost now. Need someone that has done it to explain word by word what will actually work without frying something. HELP.... Could really do with a wiring diagram for a '89 2mg but cant find one.

Just to add another theory . . . . Would one of the 1fn pick ups fit the 2mg engine and then use existing cdi and loom from 1fn. Don't all shoot me down in flames. This is the first jap bike I have had in bits and getting more confused by the minute. Old sckool me . . . . . . . . . . oxygeneuk.wix.com/oxygeneuk check it out . this is what i am used to NOT BIG JAPS . . HELP LOL

I have a 1990 2MG and the pictures I showed you are from the wiring diagram that I use. I can assure you that the differences are the ONLY changes in the iginition circuit. I don't think the 1FN pickup will work on a 2MG. I think it's slightly bigger, judging by the one that Kenny sent me.

Just checked through the Clymer manual I have and the coils (spark plug) are probably going to need to be replaced as well because they have different resistances on primary and secondary. However, I've found that the clymer manual is shite on this respect because the method of testing them doesn't work on my fully functional 2MG....

Appreciate your help Crusty. Think I will try and find some 2mg coils. Know where I can get a 2mg loom so if I change the lot I should be ok and will also have the other loom for the 1fn engine when rebuilt. So if anyone knows where I can pick up a cheap pair of 2mg coils please let me know.

Yet more confusion . . Well for me anyway ! Thought I could get hold of the original wiring loom for the 2mg engine I've just fitted into the 1fn frame . . . but he's just sold it. I've replaced the 1fn cdi with a 2mg cdi. I've established that the 5 wire loom connector to the 2mg cdi is wired different to the loom on the 1fn. I have yet been unable to find a wiring diagram that corresponds to the 1989 FZ 750 2MG loom to cdi connector. Wire colours are the same but in totally different positions in connector. Can I reposition the 5 wires in the 1fn loom connector to match how the 2mg loom connector was wired without causing damage. How come I am unable to find a diagram to suit the 89 2mg . . . or is it me? Crusty . . . . Whats your opinion ? Attachments:

You are confusing the wiring diagram. Red/White is a "earth" from the coils, it doesn't do 2&3 it does all 4... (NB don't connect them to the frame, it should only connect to the loom! It's not really an earth, I used this as a simple explanation...)
Grey and orange should go to coils. Black neutral. Red/White activates the fuel pump/goes to the coils. Black/White goes to the sidestand relay. These colours do the same thing on all looms. Just re-connect them to the appropriate connector on the TDI.

Thank you Crusty. Appreciate that. I got myself tied up in knots with this. Hate electrics. Cheers Mate.

I've had so much hassle trying to sort this so thought I would share the following in the hope it will help someone else. 1fn engine uses different ignitor to a 2mg engine. My 1986 1fn uses a TID14-39 1AE-10 ignitor box. My 1989 2mg engine uses a TID14-56 2MG-10 ignitor box. The wiring from the loom to the 6 way spade connector to the ignitor is in different positions although the same colour coding is used. The attatched pic shows the 2mg ignitor and wiring positions. This is also the same for the 1988 2mg model. Looking at the numbered terminals the following is how they are positioned on the 1fn loom 1986. 1/ Black 2/ Grey 3/ Black + White 4/ Not used 5/ Orange 6/ Red + White This is how they are positioned on the 2mg loom. 1/ Black 2/ Not used 3/ Orange 4/ Grey 5/ Black +White 6/ Red + White I found a 1988 2mg wiring loom from a company in Holland and the colour positions match the 1989 2mg loom the ignitor origionally came from. The only diagram that I have found that matches these positions can be found at www.cmelectronica.com.arAwaiting delivery of loom now so watch this space. Attachments:
