unfortunately they didn't provide any instructions, I talked with them last week and they said they would send some diagrams for the ac and pcm but haven’t received anything and now I can’t get ahold of them.
Yeah I never understood the "excite" the cam sensor, I was thinking maybe just run 12V to it? Maybe something intermittent? Ultimately I decided I didn't want to mess with some of that and thought I could utilize the J1939, but I couldn't figure it out definitively. Mainly I just wanted to try and "simplify" the wiring so I ran aftermarket gauges. Also by cam sensor I was thinking it was the sensor in the vicinity of the distributor (not sure if your model has the same setup).Axis mentioned having to excite the jeeps cam sensor to keep the engine running. I’m not sure exactly what happens if you do or don’t do this. I’m guessing it shuts power off in the run start wire which I’ll be tapping into for the Cummins ecu. Hopefully I can get some clarification on Monday.
I'm guessing it'll still need to see a pulse, but that shouldn't be too hard. Maybe Y some signal from the crank or the Cummins Tach Output. But heck try it first, no big deal to add it later I assume.Yeah I think they upgraded the vent tube attachment. It’s now just a slick sleeve that the hose clamps to.
For tach signal it’s my understanding that comes from the crankshaft sensor in the bell housing, not the camshaft sensor. So I’m hoping all I need to do is provide 5v to that input signal to the pcm but need clarification from axis. Hopefully it’s something simple and I won’t have to integrate that dang camshaft sensor for the thing to run.
I need to get that tool. I tried and tried to get those pins to release with a micro-screwdriver, but failed on most. I just hate cutting wires and stuff, if I don't have to.
