The Best V8 Stories One Small Block at Time
I got some bad news. I recommend you find a 98 engine harness. 98 is the bastard year when it comes to wiring. And you can not mix 98 and 99 stuff together with out major modification to both harnesses.
In 98 people complained on how sensitive the 98 gauges are so in 99 GM made the gauges less sensitive. And changed the wiring harness. You can mix match between 99 to 02 but 98 is the bastard year.
You run the risk of frying your PCM. I recommend you keep doing some more reading. And I dont know where you are getting your info. But keep doing some more reading.
