Help please Thetford C250 wiring

[Hymercar]

The flush on my Thetford C250 has died, the whole panel is dead. I have discovered that the wiring under the waste cassette has corroded to the extent that three wires have become detached, the problem is I have two red wires and a black one floating free and choice of connections on where to put them. Two of the wires should be attached to the fuse, in and out and one has become detached from terminal 85 on the relay. My problem is which goes where?
Does anyone have a wiring diagram (I cannot find one on the internet) or can I be so bold to ask that if someone has a similar Thetford model would they be so very kind as to remove their waste cassette and check which colour wires are attached to the fuse holder (I am hoping it is the two red ones) that is found at the back of the cassette
Thanks in advance.

Hello there, I have the same toilet (ceramic bowl) I can have a look tomorrow and let you know, in the meantime normally on a standard relay 85 is an earth/negative, don't know if you have sussed it out but the complete panel with the fuse and relay will come out with a gentle pull towards you.

Thanks Full Timer, yes I've done the "gentle" pull and the mounting is free, the hard part is removing the spade connections from their sockets so that I can re terminate the wires, there is not enough cable slack to pull the lot out into the open. Thanks for taking the trouble to check for me. I look forward to hearing from you.

Thanks for your advice Full Timer I realised fro what you sad that the earth wire will be black and the two reds go to the fuse all is back and working okay.
