and I'm still a bit confused. I have the control box mounted, the distributor dropped in @ TDC and ready to be timed. I have the clip on the coil, all of the connectors are plugged in, and now I come to the wiring up. I have been reading all of the diagrams, and I think I kind of understand it... but I don't wanna have a field day with wiring and waste my time or screw something up. There's a red wire that comes from the coil bracket. Where do I hook that up? Do I solder it to the wire that was going to the original coil? And then the red and white wire from the connector coming from the control box... the red goes to the ignition switch, on the run tab, before the ballast resistor? And the white wire goes directly to the S Terminal on the solenoid? And do I leave the wire that's on the S terminal now on there? Just give me a quick wiring plan and I'll get to work! Also, there are 3 wires coming out of the male connector that goes into the female connector on the control box with the red and white wires coming out. Where does the third wire go? Thanks guys and gals!
 
The red from the coil goes with the red into the box which then goes to the key. The old I wire hooks up with the wire that went to the + side of the coil somewhere after the resistor wire. I have heard of guys using that wire to run other accys like an electric choke or just tape it off. I have read that you dont need the white wire hooked up for stock motors all it does is gives a 10* retard for easier starting. I dont remember the other wires in the module but grounds are important. There is a ground wire in the other harness that goes to the dizzy, Im not sure if its intended to be the only one. I think the module case should also be grounded. Make sure your engine to body ground strap is in place. There was a member a while back that kept melting the wires to the dizzy and it turned out that those were the only body to engine grounds in his system.
 
Mike,

I think I just had the red wire hooked up on it (didn't use the red/white)

so I take it everything got there ok? those wires are about two years old (only 3 months of driving on them though) but the cap/rotor are unknown. so you might wanna change them out. did the box take much of a beating getting there? I know there was a corner on the bell that wanted to keep poking through.
 
Everything got here great. And just the red wire was hooked up to where? Just before the resister? Or to the S on the solenoid? And yeah, everything got here okay. On Thursday I'm going to be mailing out money orders to you and Stubbs. Thanks for everything man! The box showed up great, and your bellhousing was delivered to Addo and everything. =)))
 
I am good....it was a two birds with one stone deal. besides I prob will owe you a little gas when you pick up the xflow for me.

I ran a wire back to the dash before the resistor wire to feed the DS box itself and came off after the resistor wire for the coil power. I really should have wrote it all down before I yanked it out for the EEC4 setup.btw that might be up and running shortly if I can get this one last hole plugged on it (might need to take it in to be TIG'd up)

I'll try calling my shipper up after work this afternoon. any preference on a terminal? I am not sure if there is a local one that will work in Garden grove or if I have to get one between there and your place. I'll pm you with more info and all.
 
I hooked the original coil wire up to the new coil. I haven't run the new red wire, but I took pictures to ask which wire to run where. I'll shoot the picture to you in a little bit, got a date right now! =P
 
For the DSII conversion do you HAVE to go to a yard and find a harness or can you just run some of your own wire?
 
You can run your own wire. I think the big drawcards are correct connectors at the ends, but if (for example) you were using the GM module, then making a harness is better policy.

That's the connector coming FROM the control box. What do I do with it? (2 in, 3 out).

Is this the resistor wire? It starts out red and then goes pink at that little junction. Do I need to cut it to tap it? What exactly do I do? I don't want to screw anything up beyond repair (I know, I know... I have a roll of duct tape, nothing is beyond repair, but why do it twice?) My wiring is actually pretty clean back behind the dash. What do I do?! Hoping to have this finished tomorrow!
 
I went to the ignition switch and removed the resistor wire form there, spliced in a fresh wire so the resistor still feed the coil and a new second wire was ran full length to power the DS box.
 
That's funny, I just removed the resistor wire from the system. Then again, I went through two coils :oops: But they where 12v coils, the last one being a blaster II. I blamed the fact that they where mounted on the engine and got cooked/vibrated to death, but maybe I sent them too much voltage?

Ford mounted the stock coils on literally millions of engines with apparently good results.

The early DS2 systems retained the resistor wire in the primary circuit but the later units such as my 81 F-150 have deleted the resistor, using the same coil. Go figure.

IMHO if one is going away from stock then why not go with the GM module firing a TFI coil?

I used the connectors from a fried DS2 module to enable quick change.

I think the problem with a TFI coil is you have to mount it where a DS coil will drop in a factory points coil bracket.

btw I used a FOX chassis strut tower mount and with a little tweaking of the tabs was able to fit it to my shock tower right next to the dizzy.
 
The GM module is the way to go. Takes 30 seconds to wire up and works great.

Also a lot smaller than the DSII module.

:? :? :?
I just posted a photo of my HEI/TFI setup bolted to a big hunk of aluminum mounted on the fender. Seems to me it can be mounted most anyplace :?

that is true....BUT

some people like a pure bolt up not having to make brackets install. like I said I jsut used the stock TFI bracket and tweaked the tabs and drilled a couple holes and was done.
 
Mission: Accomplished! Wow! She wants to START RIGHT UP! It was eaaasy to wire. My god. =P I used some cool new screw together wire clips that I haven't used before and it looks wicked clean. I just gotta figure out where it's gonna like the timing. Also, my module isn't bolted down in all three holes yet and rattles like a person of questionable ancestry. Me and my homedawg got that all wired up in about 30 minutes, got all cleaned up, test drove it, and loved it! (Gotta love the smell of burnt rubber, don't ya?) I can't wait to highway test it. I gotta re-register it Friday morning, and then I'll be able to take it up to my grandpa's and get it just right. Thanks for all the help guys! I'll be able to help with this swap from now on... easy!
 
Does anybody have a wiring diagram so I can do this? I am going to be using a gm module probably.
