Wiring sanity check: Coyote with vintage gauges

[mmklaxer]

I'm getting a little more comfortable with the wiring scheme. Looking for two relatively easy confirmations:

This coil of wires is in the Chassis harness. The blue and orange go to the Coyote green and blue wires that are part of the green wire 6-plug. I'm good there.

Confirmation #1: The purple tach wire is the one that runs to the #4 cylinder. The instructions read that the purple wire is in the sending unit harness, but it's not. I'm assuming they mean to run the purple wire from the chassis harness forward into the engine bay within the sending unit harness to keep it clean, then it exits the convolute at the #4 cylinder while the rest of the sending unit harness goes forward to the appropriate sensors.

Confirmation #2: The two speed sensor wires would be the ones that connect to the transmission speedometer geared unit if necessary. Since I have the GPS vintage gauges, I don't need that speedometer sending unit. Can I just eliminate these two wires? I don't see them referenced anywhere.

Yessir that's correct. As for the speedo sending unit harness, instead of removing them I repurposed them for components I wanted to talk to in the trans tunnel, e.g. my reverse lockout solenoid.

As already stated, both your statements are correct. Two additional comments. First, there's nothing magic about using #4 for the tach. You can use the trigger wire from any cylinder. Doesn't matter. Use the one that routes the wires the way you want them. Second, don't forget to program your tach per the Speedhut instructions. For this setup you'll use the 1/2 Pulses / rev. setting. Which is not the factory default. I've seen many (maybe not you :o) forget this step and their tach doesn't read correctly.

Oh, there's a very good chance I would fall into that category....LOL!

Thanks for the heads up!
