This is probably more and an electrical noob question than anything else. I'm going though my car and trying to clean up all of the shitty wiring work I did early in the car's life and trying to fix a TPS noise issue so I'm re-grounding my analog sensors while I'm at it. Since I have basically no wiring knowledge, but want to do this right i'd like some input.

Since I'm grounding several analog sensors to a single sensor ground wire on the ECU (MS3basic) do I just use something like this? Or is there a more elegant/simple solution?

Also, is there anything else I should have other than weatherpack terminals/crimpers, (good) wire and braided sleeving?

 

When I wired the mzr from scratch I just linked all the sensor grounds as they headed back to the motor with linesman splices. Same way I split the 5v and 12v supplies to them basically. If the MS didnt have a sensor return pin you'd ground it with something similar to that.
