thanks a lot zulu. i think you helped me out when i had the problem earlier on.
i actually talked to that guy you suggested. he said he just replaces some capacitors but he wasn't too familiar with the X5 unit. and North Hollywood speedo said they don't do it. in any case, sending my unit out through customs and then getting it back again is a) expensive and b) a hassle.
i'd like to know what the problem is before i shell out the money for a new control unit. they're USD 600.
i was just able to identify the connector as X613. now i need to find out where it goes. it's bizarre that the unit works when i *disconnect* the plug. it makes me wonder if it's what's at the other end of those wires that is the problem.
