Help with wiring Volume for Marantz 1150

[e-van]

Tried posting in solid state but no bites, giving this a try. Fixing a Marantz 1150 integrated, got it missing the volume pot and power switch. I'm very new to amp repairs and find the marantz schematic a bit confusing, I cant tell which lug is which on it.
I've got three pairs of shielded wires, one yellow one orange and one red. plus two single wires, orange and yellow. red pair comes from balance, orange pair from the board with the filters, yellow from the adjoining board beneath that. Orange and yellow single wires from jh20 and jh24, I think they are the loudness?. Anyone remember where they go, probably save me alot of head scratching and doing it wrong. Looks like the jh wires go to the power supply, je go to the tone amplifier. Also Got a pot with no loudness on accident, Can I bypass loudness? put a resistor in, 250k? anyone feel like helping me play connect the dots? Thanks in advance!

Okay I think i'm getting it? orange and yellow singles go to the loudness taps, Doesn't matter which? one pair of lugs front and back is for ground, the middle pair is for jh 22 and 21 from the yellow wire, the final pair is for je 01 and 02 from the orange wire, how does that sound? I don't know where the balance comes in but maybe it is attached to the same lug asjh21 and 22 so that it is always synced with the volume?

The diagram looks like it has the balance going to the loudness taps, but again nothings labeled so..., does that sound right? Anyone? I might just try it out.
