I was wondering if anyone had a 98 pcm pinout. I would really appreciate it.

Do you mean the PIN assignment for the PCM? It's broken down in detail in the service manual. Otherwise check out teamzr1.com, I know he has one for the 99's listed.

Yes the pcm pinout. thanks

It seams that they don't have one for a 98.
