753 aux wiring harness installation

I bought a SB200 66" snowblower for my 2002 753. Had to buy a new one as lots of used 6 footers around but not with the smaller motor. And I figured 6' may be too large for the 753. Anyway, I bought the Bobcat aux wiring harness which plugs right into the existing harness on the machine. The instructions say that you can run the harness with the aux oil lines along the bottom of the lift arm, then down into the engine compartment under the air filter / over the battery and plug into the pigtail. For my machine (G series), I think(since lost the instruction flyer dangit) it said I do not have to take the end off the connector, that it should fit alongside the hydraulic lines. I can't seem to weasel it thru there, so I am wondering if there is another hole in the frame I am missing or do I need to take the engine end off the harness apart and just fish the wires thru? Appreciate your help. I can see it is snowing when I look out the window. cheers, Creek
