What engine wiring is needed b4 I pull motor

I told ya man. Google search for a wiring diagram for the year of your donor vehicle. Buying an EVTM for it might be a good idea too.

You can also Google search "Mustang standalone harness" and you'll find a ton of info.

Yes, pink wire goes TO the fuel pump, if its has 12v then fuel pump will run
Orange wire comes from FP Relay, it will have 12v if relay is closed(activated)

There can be a 2nd wire spliced to the orange wire at the FP relay, it goes to the computer, it "tells" computer that FR relay closed and sent 12v to inertia switch/fuel pump

I know.figured I'd ask while I look

So I'm about to wire my electric fan up and was trying to figure out how to wire it up since donor car has a high and low speed relay? Do I decide to choose one speed over the other and wire that in?or do I wire both speeds together and each speed turns on when temps are hit for each fan speed setting from factory?

 

[RonD]

If fan is just 1 speed then wire it to both low and high 12v wires, only one relay has 12v at a time

 

[svtcards]

So wire both high and low speed to each other, then connect both of those to power side of fan?

 

[RonD]

Yes, that would power the fan when either relay was closed
There is no voltage difference, is just 2 relays, when temp or AC triggers it, the low speed relay powers fan, if temp gets higher then high speed relay closes which opens low speed relay
But in either case 12volts goes to the one 12v wire on the one speed fan so it runs when either relay is closed, which is what you want
