Lots of pins for this C187 hookup. When I built the harnesses for the engine bay sensors, I brought every sensors power and ground back individually as well as the signal. I did that because in the Motec you can indicate which sensors are on which power supply rail and for things that are ratiometric (like temp sensors) it can correct for the voltage not being exactly 5.0V.

I need to add the end connectors to the car harness and it will be ready to install… Then on to the dyno for Timothy Bailey and I to have some fun. Thanks Tony Palo for recommending I get the 187 instead of the smaller one. Indeed I’ll need all of those inputs! Also thanks to Sharif Abdelbaset for the wiring tip.
