    '93 SL750 Update to '94 SL750

    I have been updating my '93 SL750 to a '94 SL750 and I was told that I needed to get an updated CDI because of the timing.

    I was looking at the diagrams of the different skis ('94 SL750 vs. '93 SL750) and it looks like the '94 has an electrical board (same as my '95 650) but the '93 doesn't have a board.

    Is this going to affect my update to a 94? I received the CDI and it looks like there is one wire that needs to plug into an electrical board whereas the 93 CDI (which I took out today) obviously has no wires that need to plug into a board.

    Is there a complete electrical box swap that I am going to need to do or do I not have a problem?

    What wire is in question? Only 780 CDI had a grey or tan wire for the limp mode that went to the board.

    The wire that I circled in this picture is the wire that is in question. This is a CDI from a 1994 SLT750 which had the same part number as a 1994 SL750. The wire I believe was black and yellow and is 2 pronged and looks to attach to the circuit board.

    Any thoughts?

    If it's black with a yellow stripe, I think it goes to the stop switch. The stop switch will complete the circuit to ground.

    So the original 1993 SL750 which I am converting to a 1994 SL750 did not have the electrical board but now you are saying I need it? Can I ground it any other way?

    The good thing is that I do have the board from my old 1995 SL650 but it seems like that would be the only wire going into the board? Is this correct?

    Also, the casing from the 1995 SL650 is taller than the one from the 1993 SL750...???

    I don't think the board is needed. You will want to connect it to the kill switch, not ground. The other wire from the switch will ground it to kill the motor.

    Actually, take a look at the 650's box. It should have the blk/yel wire. Check and see what wire it's connected to in the box. It should have a wire connected to it on the same terminal.

    Ok I understand what you are saying now. I think I should be good to go! Thanks for your help.

    I opened the 1993 SL750 e. box and installed my 1994 CDI and every wire had a connection with the exception of the B/Y wire which you had spoke of before that connected to the kill switch.

    The connection coming from the CDI box is a female connection yet it is a different shape and is not the circular acceptor shaped connector that gets the male end put into it like I have in my 93 box. Do I simply need to splice the wire and get a regular, circular female end to make this connection?

    The 2 wires that I have circled are the remaining wires that need to be connected (notice the flat shaped female connector)...

    You can use a male sta-con to connect to your female from the cdi or get the f/m butt connector for your existing connector. Should be able to find those at an auto parts store. You could splice them using solder and heat shrink tubing also.

    I have the CDI that I took out of the '93 SL750 that has the single Female connector that I need...is it possible to remove it from that wire and reuse it for what I need it for?
