More wiring questions

[ChrisNicholls]

Hello!

It's so hard not to ask endless wiring questions, but I have been slowly working my way forward and making good progress, I think.
I'm building my Gen 3 coupe with a Gen 3 Coyote.
Here are a few of my sticking points.

1. On the MAF and Alternator harness, am I correct that I do not need the rest of the plugs?
C132-AAT
C129 - IAT
C1743 CACCT
C1217 CPC
Cut them off and terminate the wires?

2.On the Oil Pressure sender plug there are three wires, Black,White and Red. On the harness there are only two wires, Black and Grey. I have connected Black to black and grey to white. The instructions do not seem clear for the red wire. I am NOT using an Oil Temperature Gauge (I'm using FFR Vintage GPS gauges).
Do I just cut and terminate the red wire and also the Oil Temp wire in the harness? (This is what I have done, but now not sure)
Or do I connect those two together?

3. On the same harness there are two wires, a green FAN THERMO and a peach coloured ELECTRIC CHOKE.
Do I need either?

4. The Coyote Fitment manual says on page 98 that "it's best to let the engine control the radiator fan"
Then it simply says to connect the orange harness wire to the fan's blue wire and ground it and you are done.
That sounds so straightforward, but does that mean that I don't need the thermostat switch and the fan relay etc?

Starting the gauges and switches next.

Thanking you in advance!

I don't remember all the connections but you are correct for the Coyote control pack to control the fan only one wire is required.
The second wire for the fan goes directly to a ground.
C132 (AAT) Ambient air temp is for supercharger - don't need
C1743 I don't have it hooked up.
C1217 I don't have it hooked up.
I didn't cut any off in the slight chance I want to add a supercharger later.
Hope this helps.

1. I usually don't cut wires off the Coyote harness. There are enough wires everywhere that a few extra doesn't matter. If nothing to hook them to right now, tie they out of the way and leave them. That's the safest just in case...

2. For years the Vintage gauges used a simple 2-wire resistive type sender. Some time ago, they switched to a 3-wire powered sender. More compact plus the 2-wire sender had a relatively high failure rate. You need to get 3-wires from the gauge to the sender. It's been a while. I guess I'm a little surprised this hasn't been addressed in the RF harness and the build manual.

3. With a Coyote cooling setup (e.g. controlled by the Coyote PCM) you won't use the green thermo switch wire. The choke wire obviously isn't needed, but it is a nice 12V circuit than can be repurposed for something else if you need it.

4. I just take the Coyote cooling wire directly to the fan plus side. No reason to involve the RF wire(s). Ground the other side of the fan and you're good to go.

Thank you!
To the rescue, yet again!
You are a life saver.
