I'm sharing my 5v referenced sensors with both the factory PCM and the MS3X - with power and grounds supplied by MS3X. I'm betting my noisy TPS signal is from the sharing somehow. How the heck do I clear it up?



I would do a ground bus, with the bus ground feed striaght to the bettery. Only have sensors grounded on the bus.
