Duraspark II installation --- help

[Curseoftheblade]

Hey all,

I've got a 66 Mustang mid swap. It currently has a 250 six that's in and all set to go. I'm having difficulties getting to the red/pink ignition switch wires under the dash. Any suggestions or tips for reaching them/wiring everything together? The difficulties potentially being that the 66's electricals never had a DSII engine from the factory.

Also as a fallback, i'm thinking i may just go with an aftermarket plug-and-play 2 wire distributor (scrapping the 3 wire duraspark ford one). Does anyone have any brand and model # suggestions? Ideally something that looks moreso factory than not.

I would much rather keep the DSII and Ford distributor so any advice on getting that working with the 66 electricals (especially the scenario mentioned above) would be great!

Thanks as always,

Connor

The DuraSpark II is a supper easy swap into many early Fords as long as there is a Ford DSII distributor that fits into the engine your using. Do you have the compleate matched system? This consists of the distributor, cap & rotor, plug wires, coil, factory wire harnesses to coil & control box, the control box with Blue Strain. You if you are using all Ford designed parts and its wire harness then it all just plugs togeather and you only need two wires to hook it up. You can use your original pink resistor wire (Posative / Battery post of the coil) on the 66 as is for power. A DS II system should have 9 volts going to it with the key in the run position to work properly. For parts ID and wire diagram see the below link. If you want it to look more stock or stealth the control box can be hidden by mounting it inside the car by modding the harness or building a new longer one. You can also try using a good quality cap and rotor (NAPA that has the brass contacts) or use a DuraSpark I cap and rotor will fit a DSII without the cap adapter ring. Good luck

The Duraspark system is nice and simple, the distributor basically switches the ignition module which triggers the coil to fire.

A Duraspark or other ignition module can be used with Duraspark distributor. It should need: simply two wires to distrib', one to coil and a 12V source NOT the 'pink wire' resistor wire from ignition switch.

The existing Coil should still use the 'pink wire' resistor wire and can be left alone. 12V source can use same " pink wire" terminal at back of ignition switch-with the for full 12V to ignition module with new wire thru firewall to ignition module .. my early cars it's easier to remove ign. switch.

The GM "HEI" 4-Pin module is a simple favorite. It is inexpensive and universal although the OEM Duraspark module its has fans too. ' haven't tried the recent aftermarket ford adapted GM "HEI" distrib/ignitions, probably use same GM type HEI module but don't look anything like OEM.



have fun

Thanks for the help! I have wiring diagrams and understand that. I just can't physically reach under the dash to the ignition switch to splice in to it. Any tips or tricks?

IIRC I did some combo of pulling the instrument cluster and pulling the ignition switch assembly out for better access.
