1997 Toyota Rav 4 Tach Learn Problem

I am trying to install a prostart ct-5000 into my 1997 toyota rav 4, everything seems to be working but it will not learn the tach, my tach wire is connected to black at the coil, and it reads fine with my meter, I have tried many times over and over it just wont program it, I read somewhere that it may be my IGN2 wire, I have never done a install on a vehicle with a second ignition, my prostart has a output for 5th relay which it says can be used for second ignition, and there is a jumper on the unit to set it for 2nd starter, 2nd ignition, 2nd acc, i set it to ignition, but am not sure if that has anything to do with the tach programming, please help thanks!

These Canadian Tire units have problems with tach signals that are eother too low or too high. Some of the newer models have a jumper pin that can set the unit to detect high threshhold tach signals, not sure if yours hass this or not though.Jeff

No, it doesnt have a jumper for high tach signal, my tach signal is fairly high, it outputs around 35vac, is there somewhere else I can get this signal at a lower voltage? or is there a way to lower this ones voltage?
