nothing compares to a FSM.
take Andy's advice and get one. you won't regret doing so.
in all the ones i own, i have noticed that they are real close up or down a year or two, so if you can't find the exact year of your ride [or can get a super deal on one a year older or newer], many times the info contained is the same,including the wiring.
with that being said, this is no guarantee the info will BE the same, but if you can follow it through, you will be able to decipher the [slight] difference[s] and make it work for you.
this is just my personal experience with these things over almost 60 years of playing with this brand. your mileage will vary.
