91 Camaro LSX No start!!

Im doing a 91 camaro with a 4.8.

I bought a harness from Current performance down here in Florida, Plugged and played. Now it wont crank. Worked all day yesterday, now i turn the key dash lights up, go to crank and the radio goes dark and I get nothing from the car.
I jumped the starter to make sure that wasnt it but it cranked right over, I checked all the fuses on the new harness and none are blown. WHAT AM I MISSING!!?!

I shortened the to red wires coming out of my c100 block on the fire wall but reconnected them. I'm at a loss right now...

Auto or manual? Did you bypass the relay behind the driver's side kick panel? The car itself has vats as well as the ls ECM. You may need both bypassed instead of just the ECM.

So are you still using the resisto4 key VATS system? I wouldn't think that would work on a swap. Butto me this sounds like a neutral safety switch problem. Do you have one? Is it working? If its still wired up but not hooked to anything maybe its moved and isn't in park in your neutral any more.

Is this a manual conversion or is it originally a manual car?

And ya, sometimes things work one day and not the next. The starter circuit is simple, check for power each link in the chain with a test light.

t5 turned into t56 so always has been manual. So it sounds like the vats is preventing power to the starter when I turn the key?

Nova, im using my cars original key from when it had the 305 and it worked the 6 times before I bumped into this problem...
