The hose going to the throttle body should also feed the oil cooler, I would recommend looping those lines rather than blocking them off and tucking them somewhere. I bought a 5/16" (?) brass hose barb and some hose clamps to loop mine when I installed my Skunk2 Throttle body.

I tapped the front neck delete plate to use an AN fitting as the feed line, as for the return I cut the little bypass nipple off of the water pump inlet neck and tapped it to fit an AN fitting.

Not any of the delete plate unfortunately. I got a Supermiata reroute and I couldn't stand tapping into that nice little block off plate.
What I am going to do instead (I have a 1.8, well 1.9 now, block and BP6D head) is use the oil cooler feed off of the back passenger side of the head as the coolant feed, and use the return on the water pump inlet as the return. Basically instead of an oil cooler, throttle body, bypass, etc. with all those little devil hoses, I am bypassing all of that and instead of looping them I am using them to run coolant through the turbo. Instead of AN lines I am just going to use banjo to hose barb fittings along with silicone hose and fuel injection clamps. Much cheaper, no cutting, drilling, tapping, etc.
Edit: Keep in mind I am using a thermostatic oil cooler, so the OEM oil cooler used on 1.8 blocks is not going to be necessary anymore in my case. So I have no problem bypassing it. Same goes for the throttle body, I live in Houston so it's not like the throttle plate would even have a chance of freezing in cold weather. Keep all this in mind before you bypass all that stuff if you end up going the same route. That and I'm not sure if 1.6 heads have the coolant feed on the back of the head like 1.8 heads do.
