1999 toro z master z147 kill wiring?

I have a 99 toro z master i had recently swapped to engine to a briggs 20hp v twin... If i connect the engines kill wire to the wiring harness it kills itself even if key is on. Now, if i put a test light to the black kill wire connected to the keys wiring harness to the positive terminal the light turns on when i turn the key on the "off" position but the light turns off when i turn the key on the "ON" position but either way it kill the engine which makes no sense to me...

Update:

Nevermind i figured it out
