2000 Cirrus tach sensor

Jeff helped me out on the last question I had about the door locks, and now they work fine.  The only problem I have is the Avistart 4501 I have installed in the car needs a 1-5 VAC signal for the tach feedback, and the tach wire listed for the car here https://www.the12volt.com/wireinfo/volt.asp?Year=2000&Make=Chrysler&Model=Cirrus&Table=Security, puts out about 0.6 VAC at idle up to about 1 VAC at 3000 RPM.  Anybody know of an alternative way to get a useable signal at 1-5 VAC at idle?

thanks

Thanks a lot Jeff,  you have been very helpful.  Yes, it is a BLACK/ Grey wire right off the coil.  The starter does drag, so I will have to try the injector wire, although I am afraid it will see even less voltage that way.  The unit does not have any provisions for setting the number of cylinders, it only monitors the AC voltage (from what I gather, anyway).

Hey Dave;

That's OK.....the unit is an auto learning unit so the cylinder signal from a single cylinder is going to be better than that of a 8 cylinder signal. Most of the time when I can not get a clean signal from the tach wire I go straight to an injector and works every time.

Thanks again Jeff,  the injector wire works fine.  Now I have some other issues to work out, but it is in the wiring.
