Someone with the service manual for a 88-90 bird, is there any way to see what kind of resistance the system uses to determine tach filter and rpm? i'm swapping resistors in my 92+ cavy dash and am trying to get the stock tach as close to accurate as possible.....

ps my manual is on it's way now!
1st 1st gen on air.....
