Hello all, I was hoping to get some info from the maters. I hope you guys can help me!

Ok, I am trying to use the EPS system in a project car of mine. I have it all mounted, ready for the wiring. Since I am not using the f20 motor or tranny, I need some help with deciding what to use for the EPS computer inputs. Based on the factory wiring diagram I have, the following are all inputs:
1)B+ constant
2)B+ IG1
3)speedometer signal from gauge assembly
4)tach signal from ECM
5)"EPS load detect" from ECM, speed signal maybe?
6)3 wires for torque sensor

From what I have read, the system only uses the torque signal and the speed signal to operate the EPS. With that said, why would they have 2 inputs for the speed, and a tach signal? Which of these am I going to have to simulate?

My question is that since I am not using the ECM, speed, and tach signals, is it possible to "fool" the system into working properly? Is there a way to wire it all up so that I can get the powersteering to work without those signals? If I really do need a speed signal, would a 12V with a rheostat to change the voltage simulate it for a specific speed, then just adjust it as I need?

Any other ideas to make this thing work would be greatly appreciated. There has to be a way to get this wiring worked out so that I can use it.

Thanks guys

BUMP!

someone has to have some technical expertese on this

try posting this in the "Electronic" forum section--you may get a better response--most of the folks who frequent that forum are amazing in their knowledge on stuff like this.
