Your Daylight has a large overhang on the cab effecting harness connection. So you will have some mods to do. Certain engines are harder then other and some require mechanical besides electrical work. Some engine benefit from using different parts not included in the kit, like speaker size, coupler length, harness etc... Advantage a tech has when doing this. G
Yup. There is a larger cab overhang on the PS1 version than the PS2 version I converted. When they went to PS2 the locomotive frame was moved closer to the end of the cab to accommodate the 90 degree PS2 tether. I picked up a Premier PS1 GS4 that had been converted to PS2 3V with the upgrade kit a couple years ago. Whoever did it used the 90 degree tether from the upgrade kit. It fit but the tether had to be jammed in the socket. I ended up replacing it with a flat tether and all is well.
