I bought DDM tunings 55w kit 5000 and installed them back in the summer. Also bought and installed the wire harness for them. Haven't had any issues til recently. Lately its been taking anywhere from 5-20 tries to get them to fire. I checked ground connections and power wire. All seem fine. Not sure what to do. I'm thinking its from the cold weather but I read some hit or miss posts about the harness. Is there anything else I should check, relay, harness itself, ballasts? Any help would be appreciated. Thanks in advance.
