I've got a 1990 Chevy 1500 that I put a LS-1 out of a 2000 Trans Am. I purchased the painless wiring harness for the engine, along with a brand new computer. I want to build my own instrument cluster with mechanical Auto Meter gauges. I'm not too familiar with the LS-1, and I don't want the computer to set the check engine light. The gauges that cam stock in the truck from the factory are the kind with the grey background that moves around instead of the normal needle style, so the stock truck gauges are out. I would appreciate any help or suggestions. Thanks.
