Hit a snag

[Twisted_Steel]

Got the donor engine from the 85 Mustang GT in my 91 Ranger. All has gone well until today when the wiring has thrown me for a loop. I'm using a carbed 302 HO with the duraspark ignition box.
Those of you who have done a carbed swap with a previously injected engine could be of major help. Where do I tie in the spark box to the trucks wiring harness and did you disconnect the EEC completely?
Any help is very much appreciated!
I've logged notes from my swap and have several pics that will be coming soon.

If you are using a dura spark box with the blue tab its simple. The box will have two plugs one with a 2 wire connector and one with a four wire. The two wire connector will have a red and a white wire. Connect the red one to a key hot (hot in run) and connect the white to a hot while in the cranking position. You can use the starter solenoid for the white wire just connect the wire to the starter side of the solenoid. The four wire connector goes to the distributor and the coil. The green wire connects to the NEG. side of the coil and the other three wires (orange, violet, brown) connect to the dist. wires color for color. Your pos. side of the coil will need a wire that is hot in the run and crank position.

Thanks!! I should have specified the red and white wires in the 2 wire connector, but I was in a bit of a hurry when I posted that. Next up will be the alternator. I'll have to check and see if the 4 banger alternator will work or if it won't push enough amps for the v8 setup. I've got the alternator for the v8, but it has an external voltage regulator. I can snag that from the Mustang also.

Your year may differ, my my swap did not touch the alternator at all.
I used an alt off a '93 Taurus, 130 amp and internal regulator. (my Ranger Alt would not work, mounted in wrong direction)
Also, you'll be able to remove your stock computer entirely.

Your 91 Ranger should be an internal regulated alt and you should be able to just run the wires from the 4cyl one right to the V8 one with no problems. You can run the alt in any direction and it will work just fine but make sure that it has the right fan on it for the direction it is going to spin. Your best bet is to get a 3g alt from a newer vehical as they put out more amps at idle and under a full load. Just measure the mounting bolt spacing and look thru the wrecking for one with the same bolt spacing. Converting the wires to a 3g is a no brainer and very simple to do.

Just wanted to clarify, some Rangers have MOUNTING bolts that go in a strange direction, and the original alt cannot be used, unless using Explorer front brackets. And mine was/is already 3g.

I used the Taurus alt for 2 reasons- it was about $30 new in the local classifieds, and it was the standard Mustang size. My donor car was a Mark VII LSC, and had a huge 8" ALT with an external regulator. (we had a Mustang alt bracket in the garage. We cut the tensioner off it for fun and used a turnbuckle on top of the alt.)

Gosh, that's pretty.
Makes me want a 5.0 in my Ranger, hehe.

i didnt want to start a new thread and my questions are kind of related anyways. im not running an ignition box i have a cheapo hei type distributor that has the coil built in. theres only two connections on the dist, one is the tach the other is a power. where does that power wire come from?

From any 12v+ key hot. Must be hot in the run and crank positions.
