there should be a sticker somewhere on the frame under the front fender, it will read something like trx420fm-with maybe some letters after the fm. the round connector in your first pic is normally wired into the main harness, if this is the case ?, you will have to buy a whole wire harness to solvet this issue.
Got another PLASTI_DIP video... and it's on chroming this go round and i think they have nailed it! The test samples Look great!... i'll send ya via PM.....
