I will be doing a cable throttle LS swap in my 1995 F250. Possibly using an OEM computer, on the fence about going Terminator X. I understand that I can use tunerpro and LS droid with an OBD Link LX to turn off VATS/CATS/ ect.. But I still want the OEM computer to run the gauges, ABS system, SRS system and aircon. As well as the in tank fuel pumps ( I will have the GM system trigger a frame mounted pump to carry the fuel pressure to 60 PSI ).

So I have to trick the Ford ECU into thinking that the engine is at least running. My thought is to use a tach output from the LS engine, into pin 56 of the Ford ECU which is the PIP signal. Both types of signals are a square wave 12v signal so it should be good enough. I don't have a tachometer in the dash.. This should work right?

I'm wondering if the Terminator X system has the option to control the Ford gauges, Ford ABS system, Ford SRS system, and the Ford A/C system?

Terminator X can do the gauges for certain, If I merged the dash harness, and the air conditioning as well. But it would be a tall order getting it to work with the ABS and SRS. Not that I need those systems, it would be nice to keep them.. If I can keep the OEM Ford ECU alive it will make it a lot easier.
