If anyone could point me to a right direction. I just rebuilt a top end on this sled with my father in law. Everything works great except my cluster gauge started cutting in and out along with my headlights, heated hand warmers, tail light. I followed the shop manual and all grounds seem to be secured and tightened. It started cutting in and out like a loose connection. When it randomly comes up, I can see my break-in countdown change. So everything with ECM working fine except the cluster and above mention. I tried another cluster from my buddies sled, still no luck. Where should I look? Right now it’s dead and most of the time blacked out. I want to try pinning the connector, but I can’t seem to find PIN numbers. Any help would be much appreciated.
