Ignition control Module question for a 1981 124

Post by sida555 »

When looking at parts some brands show compatibility till 1978 and some brands show compatibility all the way through 82. Are the ignition control modules the same all throughout ? I know its a gm style 4pin ICM. just wanted to clarify if anyone knows if there are differences between years. Mine works fine i just wanted to have a spare in hand.
Standard Ignition Motor Products LX301 shows compatibility till 78
ACDelco Professional D1906 shows compatibility all the years though ~83
Delphi DS10071 Ignition Control Module is another one i was looking at.

They didn't start using electronic ignition until 79. And it is a 4-pin GM part. If they show a module before 79, it's bogus.

2003 Chevrolet Cavalier (daily driver)
1999 Honda Shadow VLX 600

Thankyou for the response. So they should just work fine all throughout then ? There is no special specs other than the 4pin gm style ? The ICM is just a signal amplifier correct ?
