So I'm what they call "an idiot". I popped off the spark plug wires from the plugs on a 95 Wildcat and don't remember how they went on. I forgot to mark them and as far as I can tell, there are no markings from either the factory or previous owners. The wires are weird lengths and it isn't very intuitive on which wire goes to which cylinder. I don't have a manual (owner's or shop) and I looked at some online parts diagrams and they don't show it. Is there anyone out there with a Wildcat that could help me out? I believe the ZR's from the early to mid 90's were almost identical so if anyone has a sled fitting that description, you might be able to help me too. Thanks a lot.

Don't matter. They all fire at the same times. Put em on whichever way neatest.

I thought TDC for snowmobile cylinders was exactly opposite.

LH TDC and RH BDC ARE directly opposite- but both plugs still fire at the same time. There is a dead spark in the cylinder with the piston at the bottom. Just try it both ways, you will see that it will work either way.

wow. you learn something new every day. not to mention i might not have learned this for a while if it hadn't have been for my mistake. thanks guys.
