Converting Cat (8pin) to Bocat (7pin) for Bobcat Laser Grader

[Klima Excavating]

We are having trouble converting our 299c cat 8 pin to our bobcat 7 pin Laser Grader. We bought 2 jumper pigtails to convert from 7 pin to 14 pin, and a 14 pin back to a 8 pin but the 299c is not letting our blade automatically function. There is not enough buttons on the joysticks to let our graders 6 way functions work in continuous flow. Any ideas? Or is there a company with aftermarket joysticks with more buttons that we can wire to a 14 pin plug? Any help would be greatly appreciated. Both Bobcat and Cat mechanics are stumped on this one. They believe the only way to make it work is to have a control box inside the cab and to NOT use the joysticks for the grader. This is not a option as far as i'm concerned

Thats what is wrong with theat Bobcat 7 pin cr@p. It only works with Bobcat.
If you can get a 14 pin conection for the grader (or a way to make the grader work on the older 14 pin bobcat plug) then you should be able to convert that over to Cat.
The old 14 pin system uses power on to move a function and no power on to hold a function, just like all the other manufactuers use.
However the 7 pin system is just a box of computer voodoo that no one has solved. Just another way Bobcat tries to keep you cornered in their world.
I would be checking the coils on the grader valve to see what voltage actully makes it to the coil when hooked to a Bobcat. If its 14 volt or less dc you can build your own harness and make it work on any loader. You are not going to find a plug and play solution though.

We did finally Get it to work. (Sort of) We converted our Bobcat laser grader blade to a 14 pin. We then got a 14 pin to cat 8 pin harness from Bobcat. We still had to run another positive wire to keep power to our laser transmitters constant. We added two hoses to rotate the grader blade from side to side using the two smaller hydraulic ports on our high flow 299c. Using the Eight function on our 299 turns the laser system on While you are in constant flow. We use the two right side buttons on the left joystick for one of the up and down cylinders. You also have to flip the seventh function switch to use the other up and down cylinder.(Eliminating two speed) You have to hold the left Trigger while hitting one of those two buttons on the left hand joystick to move the other cylinder up or down. Its kind of Mickey Mouse but it beats the hell out of that control box they were trying to make us get. At least it does work perfect with the laser recievers attached and the machine in Constant flow (Automated Mode). Altorfer CAT was really scratching their heads with this. I supplied them with the wiring diagram for the grader blade. With help of Ziegler CAT and the research we did we all managed to figure it out. What a Headache.
