thank you

well i hope i have the right computer but it won't be hard for me to buy another one. right now i have a 2001 tahoe computer. i think the number is like 1220411 or something like that. i've got the 5.3 wiring harness witch i've modified and cleaned up so its not all over the top of the engine. (using the 5.3 so it all plugs directly into the body harnesses.)
