PLUMBING CONNECTIONS
Keep all hoses away from any areas where heat may be considered too extreme (such as exhaust manifold or turbo). Lines cannot be mounted
or allowed to rub on any abrasive or vibrating/moving surfaces
Installation Procedures
1. REMOVAL OF FACTORY HOSE: Take a clean drain bucket to catch the oil and place under the vehicle.
2. VACUUM BRAKES (NON HYDROBOOST): If the vehicle is NOT equipped with hydroboost, remove the factory high pressure hose from the
power steering pump to the steering box. Let it drip dry, and store in safe place. This will be necessary to re-install if the winch is ever removed
from vehicle. See Figure 2..
3. HYDROBOOSTED: If the vehicle is equipped with hydroboost, remove the factory high pressure hose from the hydroboost to the steering box.
There is only one high pressure hose going to the steering box. See Figure 3.
4. NOT SURE?: Which one is the high pressure hose? The hose with heavy duty crimped on fittings. The low pressure return lines from the
steering box or hydroboost both end up at the pump reservoir will have hose clamps or something similar.
Does the factory hose have a sensor in it? What this does is increase the rpm of the engine slightly when there is high power steering pump
pressure during idle. We have found this is not needed. Remove it from the factory hose and install it back into the wiring harness plug. Tape it
securely in place. The vehicles computer will not be affected.
5. INSTALL THE ADAPTERS: Take the MM adapter kit for the vehicle; match the fittings up to those on the factory hose you removed. Re-use
the factory “O” rings; install them on MM fittings if required. There may be more than two fittings in the kit due to multiple applications. You
will only need two of them. Install them and tighten to the factory specifications. Take the solenoid fittings (“M”/90-50067 and “O”/90-50091)
place into the “P” and “T” ports of the black solenoid valve block. You will have to look and see where they will best suit your application in
mating up with the hoses from the engine bay. Then add the 90 degree “N”/90-50060 fitting to the straight fitting “O”/90-50091 you just in-
stalled. Remember the hoses will come thru either the grill or under the truck in an open area. When you are sure of where the fittings will face,
tighten them in place making sure the “O” ring is compressed (tight) or for the flare fitting, ¼ turn past finger tight.
