ECM removal

Have you downloaded a Service and Repair Manual from <countrycat.com> ? Even a parts manual might show.

I have the service manual - it doesn't help. Will look for a parts manual, thanks Wallamatogus.

It looks like I'll have to remove a lot of plastic to get at the little thing. Maybe easier to remove just one piece of plastic - my Visa card, and let someone else do it.

Ha! Years ago I found a great ATV mechanic. $70/hr and he's fast. When I first got my Arctic Cat 700 Diesel, he had no problem changing out the timing belt, reclutching it, adjusting valves, advancing fuel injection timing, replacing a rear CV joint, etc. I would have screwed something up and had skinned knuckles, for sure. He works on all makes and he's fond of Cats.

ECU should be under the seat.. Its a couple of screws and one connector.
Why do you want to remove it?

On my TRV it is a little further back than that and I'll have to remove the storage box to get at the plastic. It isn't a priority yet but, if I can't find any other reason for the engine struggling after going through a shallow puddle, I'll have to check this connection and clean the contacts.
