Running Bobcat 753 without auxillary solenoids?

I've almost finished up installing my rebuilt control valve. I cannot, for the life of me, find one of the solenoids that controls the auxiliary flow. Is it OK to just leave both of them and will the machine run and operate (minus auxiliary attachments, of course) without them? My bobcat is a 2000 753 Advantage Series, whatever the advantage part means...
 
Absolutely, just like your not using them.

Thanks very much. I have one other question, its been so long since I took the thing apart I can't remember where in the wiring harness to connect the solenoid on top of the BICS valve, and the solenoid that sits in the middle on top of the chaincase (guessing its for the parking brake). I have a service manual but looking at the wiring diagrams hasn't helped much. Is there a way to look at a connector on the wiring harness and look at the connector on the solenoid and tell which plugs in to which? Several of the connectors are the harness have the same color wires leading to them so short of trial and error I'm all out of ideas, lol.

The one on top of the chain case is the park brake, it has 3 large wies going to it. The other two I'd have to pop the cab for a look. Maybe in the morning.

Thaks, I'd really appreciate it. I got a picture of the wiring harness connectors and marked the location of the two solenoids that I'm trying to figure out where they hook up. Connectors labeled 1, 2, and 3 are all in the same piece of flex tubing. Connector 1a is in a different piece of flex tubing that dumps it out closer to the solenoid labeled ???. I'm not sure what solenoid ??? is, thought I think its some kind of a bypass. Earlier, I was able to connect connector 1a to the BICS solenoid, and it allowed me to lower the lift arms and operate the tilt, but I have a feeling thats not where its supposed to be plugged in to. Thanks for any advice. http://img263.imageshack.us/img263/8919/bobcatwiring.jpg

we have a tractor that is experiencing a similar problem, the bics led lights light up, except for the one that has a pic of the arm and tilt, I think it says "valve" , it does blink so I am assuming that indicates a trouble code of some sort, does any one know where a good start would be to solve this problem? thanks

Count the number of flashes and use the chart below to find the problem.

Does anyone know how to figure out this wiring issue? I've checked and double checked the service manual and it really is of ZERO help - all the connector names in the service manual don't come anywhere close to some of the connector names on the wiring harness. For example, some of the connectors on the harness have "PED" and "60" written on them, or "PED" and "24" on another. I've got no clue as to which solenoid to hook them up to.
