Key switch r no key switch

[Pj Uptmor]

I bought a 2001 roller with no engine are wiring harness. I found a 2004 engine with wiring harness. Got the frame pc and up grades to front and rear brakes system. Now I got a roller again with engine in the frame. With the new wiring harness my on / off switch didn't work with the new wiring harness. Got one comning now. So do I need to install a install a key switch or can I just by pass this switch. If so what wires need to spliced together or none at all. HELP ..
THANK YOU

I just unplugged my key switch cause I lost the key and it works. No need to splice wires.
