wire routing

[cwhubb]

Hello again,
I bought a new engine harness for my 70 440 charger and I need directions in lay-man terms on where the wires hook up to. Cant use the old one for reference cause it was so hacked up, wires were hanging unplugged, a real frankenstein's monster. Also, dont laugh but I'm dyslexic (for real) and I cant understand wiring diagrams or schematics, hence the need for lay-man "the brown wire goes here, the purple goes there" ie.
Thanks

I would suggest laying it out on the ground. If it came a bundled up this will help rather than trying to do it on the car. From there you can kind of position it in reference to the bulkhead connector. Since you know where that is on the car, you can get an idea of where the wires go. The longer ones go toward the front. You should be able to pick out the thicker wire to the alternator so you know where that will go. Once you kind of get it how it will lay out then you can put it on the car. From there the wires should be somewhere close to what they connect to. Then if you have any problems, snap a picture of the wire or connector and put it up and im sure somebody here can tell where it goes

thanks Hemi, the ones that stump me are the female spade connections, seems to be alot.also the thick blue fusible link, does it go to the starter relay?the pic idea is a good one and I'll use it.

I agree with Rebel. Pick out some obvious connectors like he said the large black with a ring goes to the alternator, and that area should also have the single green and blue alternator field connections.

Pick out things like the regulator and other connectors. Once you get "the obvious" we can help you with individual wires

Keep in mind that the harness you bought MAY have options that your car does not have, IE is it wired for Mopar electronic ignition? Some cars had idle solenoids and distributor retard solenoids, so you may end up with a few here and there that are a dead end.

440, the harness has the six pac option, which like you said has an extra spade connector for the idle solenoid. it's not an electronic ignition harness. does the blue fusible link connect to the batt side of the relay?
Thanks

ya,it supplies power to the car from the relay.stacks up with the hot leed on the post.

dont know which spade to connect these to

 

[cwhubb]

the unknown connections

heres the wires that I dont have a clue on

 

[cwhubb]

like I said it's a six pac harness

BTW I figured out where all the spades alone the firewall go to... wiper/blower moter ballast resistors they are painted black and blended in

You didn't buy a small block harness didja?? The two ring connectors should be the coil, but they look too short?? Blue should be coil, and should show continuity back to the ballast connector which should have a blue and brown. The "hot" ballast resistor connector should have two (or three) blues coming out of it. One is power from key, other is jumpered off to regulator.

The other ring wire if factory should be green/ yellow going back to tach. However, is that harness upgraded to accomodate Mopar electronic ignition? If so that ring terminal should go back to the ECU connector.

The two greens (red stripe) you have in your hand should be horns

The two hanging down towards the alternator go to the alternator fields, does not matter which is which.

The long blue with the odd spade is probably the idle solenoid

I don't remember where the washer bottle is on those, the brown is probably for that

oh crap! I probably did buy a small block harness. can I still use it with mods or should I buy a new one?

my head hurts...

 

[cwhubb]

and no the harness isnt updated for electronic ign

progress

Update on the harness wiring, got it pretty much figured out, found some old shorts and scorches but they're mystery wires, dont hook up to anything nearby. I'll have to look at each spade in the harness bulk head connection and cross reference it's function.

Thanks again Guys
