gearhead204 Posted September 13, 2013 Share Posted September 13, 2013 I have a 89 rw713 I swapped engs. and installed another e9 but its a 95 with elec. tach. so I thought i'd swap tachs. called the dealer and got a ametek tach o.e.m. in newer superliners. however they cant tell me how wire it in. theres a six pin plug on the back with one black wire and five white wires. I've been trying to contact ametek, but no luck. if some one has one could you please help!!!!!! I think the blk.wire is a gnd. one white power two more wht. signal and last two wht. dashlite. don't want to hose up a 230.00 gauge if some one has one and could make a diagram and fax or email to me would be very awesome fax [509] 223-3415 email rginlow@live.com Quote Link to comment https://www.bigmacktrucks.com/topic/32763-superliner-electronic-tach-need-help-please/ Share on other sites More sharing options...
