My buddys got a 96 Prelude with a H22. he put on a header and greddy catback. After he started it and drove it his speedo didnt work. his tach didnt work, his vtec wasnt crossing over and his alternator wasnt working. it was a sudden thing that i doubt has anything to do with the header and catback installation. I suggest he might have tugged on some wires somewhere and snapped them but im not positive. Any ideas?
