Anyway, I added RGB SCART, but now I also want to add back the component input to use with PS2.
From reading up in this thread I think it should be possible but I could use some help interpreting the service manual.
Tracing back the jungle inputs (36-39), it goes back to a header CN303. This looks like a good place to inject the signal.
My understanding is that I need coupling caps in the path and terminate the signals with 75 ohm to ground. Looking at the diagram there and highlighted pins:

RY: Coupling cap in circuit. Seems to be grounded via R312 (470 ohms? should R312 be removed?). It's also connected to Q302/Q303 matrix transistors (?? what's that about ??)
BY: Coupling cap in circuit. Not sure what diode to ground does, i assume it still needs termination with 75 ohm?
Y: Coupling cap in circuit, no grounding. The Y input will be split to go to jungle input and svideo luma so it shouldnt need termination?
YS: Havent figured out what voltage this needs to be yet, will have to check chip data sheet later
anyone able to help me decipher this to speed things up a bit?
