Where to splice prestone flush kit?
I gotta change my coolant, but didn't realize how bad it really was. Rather than draining and filling several times, I'm considering a prestone flush tee. Where do I splice it in? I'm thinking it gets spliced in the hose adjacent to the oil fill cap. Am I right. Anyone have a pic of their flush kit? Any help is much appreciated.

If I remember correctly they say to put it on the heater core inlet line which is to one on the right as it goes through the firewall. I put one on both the inlet and outlet lines so I could back flush through the heater core because I had some blockage in mine.

IMO don't install it period. Installing the tee creates a restriction in the heater hose due to the OD of the tee being equal to the ID of the hose. The end result is less coolant flow into the heater core and less heat output from the core.
I always disconnect a heater hose and connect the garden hose directly to it.
