93' 2.2 in 79 brat, runs like a top, but how do I get the tach to read the signal from the coilpack, spliced into one of the wires just below the coilpack and I only get 1/2 the rpm's on the dash, I.E. at redline the tach only reads ~3200 r's

kinda pidlty question, but I'll just have to get into a fsm and see how the legacy tach gets it's signal, just looking for somebody else to have solved my problem first...

some pic's of the exterior and whatnot are here: http://www.ultimates...=500&ppuser=741

if you got your harness out of a 1990-1994 car, and have 4 yellow plugs that go into the ecu, the plug with 16 wires, or 16 spaces for wires, it is pin 16 on plug B56. if you pm me you email addy, ill send you the 1990-1994 FSM ECU pages, it might help you out.
