Default LS1 Harness Connection Map

Hi Everyone,

I'm turning into the home stretch of my conversion, http://forum.ih8mud.com/80-series-te...-ls1-swap.html

Since I'm new to LS1s, I need to learn what all these sensors are all over the engine are. Is there a link that lists them all out and more importantly, where they are on the engine? Or should I buy a FSM for my engine? I read the FAQ and did not find the answer.

Thank you for your help.

I know what you're looking for, but don't know where a comprehensive list is. Something like this, but for an LS1:

And did you figure out that 2nd return on the PS pump? Hydroboost for the truck brakes. You can cap it, or tap it and put a bolt in it.

If you don't luck out, you might pay for alldatadiy.com. That's what I'm going to do when I get that far.

It was for a PS fluid reservoir.

What is this? It had line connected to it that ran into the fuel line. I though it was the return until I looked a friends engine. He just had his capped off.
