 Topic: 1973 Montego w/351 HelpPosted: 28-July-2019 at 2:36AM |
|
i just purchased a 73 Montego. Previous owner had it running on l.p. and then switched it back to gasoline. Was rewired back but now i have wire nuts spliced in two sections with new different colored wire in between. Excess wire wire everywhere and stuff left with bare copper on the motor. I have a repair manual but that only can do so much in this situation. Pics would be help of others setups. Or if someone knows of a harness i could purchase, i cant find anything on here or ebay.

We have a 1973 wiring diagram here that you can download: You might be able to get a used harness if you post a want ad in the classifieds, someone here might have one. Also check eBay and CL for people parting out cars (remember Torinos are the same as Montegos).

Try looking for a 1972-1974 Harness. They should all be the same. If you're going to solder in new wires, use marine shrink sleeves and waterproof connectors. Its time consuming but, you're going to like the results.

1975 was the change to electronic ignition. There are some differences. Removal and rerouting of some wires is necessary.

and connectors for the same thing got changed for no apparent reason. the big thing is to get a harness for the same type of gauge cluster and similar options you have in the car if possible, that's where things get really different!

cluster will make a difference as will the engine as some engines had sending units in different places it would still work but you'd have to shorten or extend a wire or two... some 74's had electronic ignition some still had points.
only harness i have left available is a 76 with a 351M (need to fire the engine before i pull the harness and sell it) |

i would just untwist / untangle and rework the wire nuts with solder & heat shrink and cover them with tape & convoluted tubing. the E-Tron module may be good quality, internet search shows they're USA made. 1 wire at a time!

Its not that bad. Just do one wire at a time. I've done it to a 1973 with a 302. Once I was done, I realized it wasn't that bad. Just know when to walk away and clear your head. Then come back and complete another wire.

i hate to say it but you are in the category for a GM 4 pin module conversion with that mess. here's a link to a Duraspark schematic, https://www.pirate4x4.com/forum/general-4x4-discussion/284922-need-info-bare-minum-wires-duraspark-system.html the several i've just looked at all run a green wire from the coil - to the module. here are some i have saved,   and a GM 4pin schematic  |

the relay is because a retrofit application like yours being a 1973 model year car? has a resistor wire feeding the coil that supplies less than 12v. the Duraspark system is looking for full battery voltage so a relay is used to get that. notice the relay is triggered by the original power to coil wire and feeds battery voltage through to the module Red & White power inputs. IIRC the Red & White are not connected to the same source from the factory, one is connected to Start or Crank and the other to Run i forget which is which ATM

I also have a Dura Spark with HEI module. I agree with the others this would be the opportune time to do the conversion. Running a relay is a good idea even if you don't have a resistor wire. This way you don't have all the ignition's power running through the ignition switch.

Remember, before Duraspark, there was a similar system that was used in a few Fords...
And little to no parts are compatible with Duraspark

Duraspark 101 by George Pence "
Breakerless ignition showed up in North American Ford vehicles in 1974.
The first ignitions were not called DuraSpark; they were referred to as
breakerless ignitions. The modules had a green wire strain relief with
two harnesses, one connector with 3 pins, and one with 4 pins. I mention
these modules just to make you aware of them, the Duraspark modules are
more desirable for ignition swaps.
In 1977 Ford began referring to the breakerless ignitions as DuraSpark
ignitions, and released two modules .... "

We have some decent ignition discussion in this thread:
It also covers off Todd's Dura Spark/HEI ignition setup. The 1974-76 systems that Randy mentions are the Ford Solid State Ignition or Ford's Breakerless ignition (I have seen both names used). They are similar looking to Dura Spark, but like Randy says, they use different components (wiring harness and ignition modules). It's best to stick with a Dura Spark II or if your lucky enough to find the components the even better Dura Spark I. Both of these only went into production for 1977.

I do have a 1973 Duraspark harness if you need one. It's been sitting in will my totes of Torino Electrical stuff for years. Came off a Gran Torino that had a duraspark setup, but it was bolted on the driver's side fender well, not the passenger side.
