Anyone know where I can get a good wiring diagram for a 73 Challenger? I can't seem to locate one.
Thanks
Larry

Try;

http://www.moparmanuals.com/mopar/main/home.asp

Handy hint.
If you use the search feature under 'utilities' in the left frame you can search for key words and phrases like 'workshop manual' for example to find older conversations about stuff like this. Happy wiring!

Here is one.

I just wired my hole care and I purchased a diagram from http://www.classiccarwiring.com. It was $24.55, but in full color and easy to read. It helped alot. Hope this helps.

does anyone know of any p\lace that sells used forward engine control harnesses?.......im not paying what year one wants...thats absurd for a few wires and a plastic plug......and im only usiing a few wires from the original anyway since im hard wiring in a msd.....so it makes even less sense to pay 200 bucks for it through them......thought maybe has some take off or old stock?.......anyone?

You could try http://evanswiring.tripod.com/id3.html He used to make custom harnesses for MoPars.

What do you mean by forward engine control? Is this the harness from ECU to dizzy.ballast/coil? Or the whole engine bay harness? If its $200, that's about a good price as there's quite a bit of wiring there- horns, lighting, engine connectups etc. Frederick Dodge want $39 just for the positive battery lead to starter/relay!!

[dave-r]

If you don't need all the wires and are just making a few simple connections I don't understand why you don't just make one yourself? All the materials are easily available to do so.

I used these diagrams and founf them better than the ones in the Dodge factory repair manual.

[dave-r]

Very good! Thanks.

has anyone got a Hi Resolution of these wiring diagrams for the 73 Challenger.
I have printed these off but cannot read them, having trouble with working out my wiring through the bulkhead connector so need a good diagram.
My chilton manual only has the engine compartment!

If you have - please e-mail to m.hollingsworth@ntlworld.com

[dave-r]

They are high resolution?

You are clicking on them to get the full sized image yes? What you can see there is just a thumbnail image.

[dave-r]

I have saved the image to my pc and then printed it and it prints clearly in A4 no problem at all.

[MattH]

Must be my eyes!
I have now found them on the my mopar website. I thought it only covered to 71 , but dug a bit more and found 72 onwards

[MattH]

It is also my computer ignorance. I am learning as much as about PC's as Challengers now!
Thanks for your help Dave, i shall now have a fault finding evening.

you can also use your favorite search engine to find colored wiring diagrams. I've found it much easier to use.

Thanks that does look good.
I have found the hi-res black and white and got the ignition wiring working now. Onwards and upwards.
