Id like to wire up a relay off my wot switch to send a negative signal to my pcm pull timing. I don't want to forget to flip my switch and blow another head gasket..

For an LS1 you can use one of the custom OS's to do this.

Yes I already have a COS5 in my truck with the switch to pull timing, I'd just like to have it tied in with my arming switch or my wot switch with a relay so I don't forget about flipping the timing switch also.. I just need a diagram on how to wire it..
The LS1 COS tutorial shows how to pin/wire the switch...
see page 13 here: COS LS1B Tutorial.pdf
Yea I already have a switch grounding pin 56. And a switch to arm my nitrous, I just want to have 1 switch and not two. I some how want a wire coming off my wot switch which is positive to go to a relay and send a negative signal to pin 56.
Time to call an Auto Electrician, should be a simple job for them to wire up.

The positive wire coming from your WOT switch activates a second relay, this second relay connects PCM Red:56 to ground...
depending on the WOT switch used a second relay may not be necessary (if it has multiple throws)...
like Ross said, let an Auto Elec. look at it.
I do all my own work, I've never had any one do any work for me on my truck. I'm just looking for what I need to do whether run a different wot switch, what type of relay and a wiring diagram.. Figured someone would know what I'm looking for.
You can either use 2 relays to flip 12+ to a - signal or use a nitrous controller to ground the wire when it cuts on. I havent done it the 2 relay method in years, been lating my nitrous controller do it for me.
