OK guys, I don't have the instructions on how to wire this thing up. I am not quite sure where the hobbs switch wires into or where the buzzer hooks up at. I had a CRAZY idea, but hear me out on this one. I am going to run a MSD Fuel Pump Booster, so I will have a seperate set of lines running to the fuel pump, and the old ones will be of no use. Could I somehow use the unused hot wire for the oil pump?? Seems it would work....sorta, and wouldn't it prime the pump like it does the fuel pump? But like I said, i'm not sure how the presure switch fits in. Thanks

 

And I would also like to know how or if I can wire up a manual HI override switch.

 

The unused fuel pump hot wire should be sufficient to power the STS oil pump.

There is no benefit to trying to prime it as is only scavenges the oil coming out of the turbo housing. If the engine is not running, no oil will move.

The buzzer connects to the pressure switch at the oil pump inlet, alerting you if oil pressure builds above a few PSI inside the turbo. The Hobbs switch should connect to a relay and a high wattage resistor. Basically the oil pump runs slowly at 6 volts (I haven't measured it) with no engine boost and kicks into high (13.6 volts) when boost is made. The manual switch is in parallel with the Hobbs switch to energize the high/low speed relay. If the truck sits well below freezing temp, manually running the oil return pump at high speed for the first few minutes will prevent high oil pressure from going through the turbo's seals.

 

OK, that is helping alot, but I am still a little confused. Would It be to much to ask for some sort of drawing or scribbled diagram?? Thanks

 

I'll see if I can find my instructions

 

Sweet, thanks man.

 

I wondered about that as the way STS has it the oil pump is t-tapped into the fuel pump so when you push the key to the "on" position it primes the fuel pump and the oil pump since they both get there signal together, right?

When I got the turbo for the Hemi there was no override for high on the oil pump but the new design comes with a switch for colder climates built into it.

Attached are some instructions:

 

Can you run the pump in high all the time by just running it in conjunction with the fuel pump?

 

I think you can just connect the terminals on the hobs switch with a jumper wire but why would you want to be in high all the time?

 

are the instructions same for a trick low mount reverso oil pump??
