4l80e trans harness to a 99 ls harness Ok, I have a 2000 ls1 harness minus the trans wires. All was removed due to me running a powerglide. Now I'm switching to a 4l80e trans. I need to install the trans wires to this harness for a 4l80e. Is there anywhere I can purchase the trans harness part to pin back to the pcm? Can I pin in a 4l80e trans harness back instead of the 4l60e? Thanks.

the 4l80e and 4l60e harness is essientially the same. Just a few wires moved around.
LT1swap has info.
this site has info.
you can buy a repair harness that has the plug and about 8" of wire, you could extend that back to the pcm...or go junkyard digging...etc
