Hello new to the site from New Mexico. I recently picked up an 89 350 from a person who said that it just needs the cdi replaced to the original one. He had a Japanese one on there to show me that it started. The four wheeler runs nice as long as you kept on the throttle but would not idle once you let off of the throttle. So I figured maybe needs a carburetor clean also. Anyways long story short bought four wheeler for 300 get home to see that a lot of the wiring was spliced or not connected. Get on eBay to by a new wiring harness that is supposedly for an 86-89 got it in today and the connection for cdi looks different that's about all I looked at right now. So before I go looking at all the connections is it possible to switch harnesses? My four wheeler has the grey plastic around the lights and ignition this harness has black plastics around the lights and ignition don't know if that makes a difference between years?
