67 coupe, 200 I-6
Can anyone tell me where this is supposed to go? And how it needs to be hooked up. It is hanging loose and hot wired into the battery now.
Thanks.

Hi Alajones,
I could help you, but unfortunately my 67 drawing diagrams are at home, I'm overseas until Sept 8th. I had a 65' 6 cyl, 200 cu in, and it is an easy hook up, but the color codes might be different for a 67.
In the meantime, it would help if you could clean things up a bit, get some more lighting for the pics and take some shots of your battery terminal, solenoid, alternator and a better shot of the coil.
It looks like there's a lot of surface rust in the engine compartment from the pic you provided and from what I could see. You eventually will have to ensure that ALL wiring connects are solid, including all grounding fasteners/wiring terminations.
I'm sure a member who's at home could shoot you some wiring info and/or diagrams and good advice. If not, I'll jump in again on Sept. 8th if you still need assistance. Cheers, Tony

Odds are that the resistance wire fusible link that supplies the power to the coil is open. If you go the the bulkhead connector (on the firewall above the master cylinder) you will find a red-green wire that should go to the coil positive terminal. That red-green wire should have about 9 volts when you turn the ignition switch on. If you turn the switch to the start position the voltage should go up to 12 volts. (that is a by-product of the starter selenoid wiring.) If that red-green wire does not have ANY voltage on it, check under the instrument panel for a red-green wire from the ignition switch to the body connector. At the switch you should see 12 volts when the key is on. There is a resistance wire fuseable link between the ignition switch and the body connector. It has a barrel connector near the ignition switch and goes into the body connector. Good luck.

What Doc said.:bigthumbsupAnd as he said that red wire should connect to the firewall connector near the brake master cylinder. Good luck!

As far as where it should be mounted, anywhere on the engine is fine as long as the ignition wire can reach it, but on my car it is mounted next to the fuel pump at about the same height on the block. I was curious, what is that bracket on the left side of the picture up and to the left of the distributor?

Okay so in the first picture, you can see the wires coming out of the firewall next to the master cylinder. Either they are all really dirty, or there is no blue or green wire. But they are also all still together and unmutilated.
So if you look at the second picture, there is a wire running to that thingy on the engine block and the wire is not hooked up to anything. Is this what goes to the coil?
Is there a bracket I need to mount this somewhere? I'm really at a loss as to how this thing is supposed to be correctly installed.

In pic #1, the 3 pin top (black colored) connector has a RED-GREEN wire that goes into the bottom (red colored) connector and becomes a heavy BLACK wire. That should be your coil voltage wire. It should measure about +10 volts when connected to the coil IF the points are closed.
In pic #2 I THINK the BLACK wire you are holding should be pluged into the coil where the RED wire is connected.(pic #3) Remove the RED wire and the nut and plug the connector onto the coil stud.
This is only going to work if the resistance wire in the harness is not open.
There is a bracket that bolts the coil to the engine block. Look at any I-6 engine picture and you can see it.
Good Luck.

Thanks Doc.
Okay three more really rookie questions:
What is that thing on the side of the engine block that the wire I'm holding in pic#2 is going to?
What is the circular thing next to the distrbutor that all the hardened lines are coming out of?
Would replacing the ignition coil with an aftermarket one make any difference?

Like Doc said, it should be the coil wire. I've attached a pic of my 65 setup which should be similar. There's a chance it COULD be the water temp wire which plugs into a sensor in the back of the block. Your oil pressure sensor should be plugged in, too. These are labled in my pic.
What is the circular thing next to the distrbutor that all the hardened lines are coming out of?
Are you talking about the fuel pump? I also labeled it in the pic. Mine may be different than yours, but the location is the same.

It won't fix your wiring issues. If the coil is bad, then yes, but I'd try to figure out where everything goes first. Maybe someone else here can tell if there's a test for a bad coil or not, but I don't know.

- Correction, the temp sensor is in the back of the head, not the block, but the pic is correct.

That's awesome dude. Thanks.
I see you have upgraded to the electric fuel pump. Do you have any other upgrades to your 200?
As far as the coil, I was talking about if upgrade to an MSD or something aftermarket makes a noticeable difference in driving or if it is just something nice to have.

Oh, I wasn't sure what you meant on the coil. I've never used a "fancy" one, so I don't know. Mine is a basic one from autozone.
My fuel pump isn't electric - I think it's different from yours b/c mine's a 65. Everything on mine is stock. If you haven't seen them, the forum on fordsix.com and classicinlines.com are good resources for mods and Ford I-6 help.
Good luck!

67 I-6 Starter wires
Okay, so I got a new wiring harness from the firewall to the coil. I'm basically taking a step by step process here on my car. Step 1, start it.
So I got a new battery, new harness, new plugs, new wires, petronics electronic ignition conversion, oil, oil filter, gear oil for the tranny, steering box and differential, radiator cleaner and anti freeze for the radiator.
I think I got all the fluids and electrical stuff covered except the wires on the starter are worn, dried up and exposed in some areas. I've been looking at all the usual sites for this set but do not see it. Is this easy to just to make on my own? Do I need a certain type of wire?

If the red wire is coming off the battery going to the coil it puts 12 volts directly to the coil and will fry it in a very short time if left running that way. Running a wire directly from the battery to the coil is a old way of checking the coil to see if its firing if you are not getting fire to the points. I would get a new coil, points, condenser, rotor and hook up the original wire to the coil and try that. Running 12 volts directly from the battery (the pink wire cut the voltage back once the car has started) will fry a lot of stuff in a very short period of time. Once the car is running with points then do the electronic conversion. As for the cable to the starter get a good one from advanceautozone or somewhere and go from there. Just my 2 cents.
