Wiring loom Construction Help

Hi, I'm in the process of building a mil spec loom after completing the wiring courses. With the help of AI I have made a wiring spreadsheet and was wondering if someone could please check over to see if everything is correct and are in the best possible terminal positions.

I think you will have issues with your 5V A and 5V B power supplies and the returns. For example, your throttle body, only has a single set 5V and 0V pins, but you have noted that 5V A supplies TPS1 and 5V B supplies TPS2 -- this can't be true, so you need to pick one power supply for both TPS1 and TPS2 and make sure the matchine 0V return is used.

Your sheet "Factory Relay Source Reference" shows some of these issues -- pick a single M130 pin for the various 5V supplies and make sure that carries through to all the right places.

The multiple 5V power supplies in the M130 is where most folks seem to make mistakes in the wiring that only shows up when trying to configure / calibrate the individual sensor resources. Also note that the temperature inputs have specific 0V returns that must be used. See the help in M1 Tune for info.
