Gen 1 sbc 350 and knock sensor with Holley HP EFI?

I have a 1984 crew cab K30 that has a Gen 1 sbc 350 with 4-bolt mains that I'm converting to EFI with edelbrock pro flo xt manifold with a Holley HP ecu and turbocharging with HD8088. Has anyone setup the knock sensor on these year engines? Are you using the stock location of gen 2 sbc or welding your own? Can't find info on Gen 1 blocks knock sensor installation for stand alone ECUs.
