I have a 1995 sport 400 4×4 and the cdi has a short in it. I was given another that has the same number of wires but there is a green wire on the new one and a blue wire on the old one. I don’t want to try it for fear of damaging something. I have no numbers on the new one or even know what it came off of. the old one has cu2510 on it. thanks in advance freight
