Fully labeled 70 Charger rallye dash harness *CORRECTION*

[nvrbdn]

dan, the yellow m2e 18y to right door light switch, the black elbow to the map light switch, light socket is map light and connects at the same place as the glove box light.

[nvrbdn]

the eighth picture wiring diagram down top right shows these wires that i believe you are showing with the pink running to the light yellow to the switch , other yellow from the switch to right door switch then continuing to the instrument panel main harness.

Here is a picture of the A01 harnesses (except for the glovebox lamp and ashtray lamp which are self explanatory).  I have labeled what I know, and have the one unknown connector question.

Here's a theory.  Since they changed the ignition switch style in 1970 and moved it to the column, is it possible that my ignition delay harness was also used as a superseding part to 68 and 69's?  Take a look at this 69 ignition delay harness.  You can see the 68-69 style ignition lamp (square bracket with round hole) has a spade connector on it, and its yellow lead runs to the same source as the yellow lead that has the white plastic barrel connector for the 70 style ignition lamp.  Could that be possible, thereby meaning that the 70 harness can work for both implementations and I just don't use the extra connector?

that wire doesnt exist in my book that goes to 69, so im thinking that it could be as you say. it is definately an after 69 accessory wire.

[Nacho-RT74]

the wire what feeds the bulb is the one with BLACK plug. If you note and unless my eyes and the pic angle are cheating me, the extra wire is spliced into the same wire what plugs to the door source at harness, SO that white plug is driving door ground signal, and not a positive output.

MY THEORY is the extra wire to to feed or give door ground signal whoever will need it, becoming on an splice from the original location on underdash harness for it. This could happen on a FULLY ACCESORIES equipped car, when original sources on underdash harness are not enough.

One example based on my 3rd gen experience:

the 73/74 Chargers just have 3 accesories locations on underdash harness acc feed. If I fit the AC clutch, rear deffog and electric trunk lid latch, I will be full and I can't feed from there the Cruise control. HOWEVER on a Cruise control harness I got, it has an splice to feed from there another accesory on the wire what pluugs ond acc source. So I will have to plug on the underdash harness the cruise control, the rear deffog and AC clutch, and from Cruise control acc source splice, the electric trunk lid latch

[BananaDan]

On a 68/69, the black plug is the feed for the ignition lamp bulb, correct.  But not on a 70.  On a 70, the white barrel connector is the feed wire for the ignition lamp bulb because the wire coming out of the column for the lamp has the same female version white barrel connector.  The black plug does come from the same feed area on the main plug, which is why I think the 70 harness might also be able to work on a 68/69 to feed the different style ignition lamp bulb which uses that type of connector.  So I'm thinking I don't plug anything into the black plug.  It's either redundant to serve for 68/69's as a new replacement harness from their harness, or it's for additional accessories that I don't have, A/C or cruise control like you said.

well as I said, is hard to tell by the pic because the wires are crossing over on it

( the cruise control deal was just an example about a harness getting an splice on it )

but as far the door ground wire and the wire to bulb are not spliced into the same plug cavity, everything will work correctly.

editing:
NOW I REMEMBER... on 71s the SEATBELT LIGHT is also delay time flasher controled. Are 70s available with seatbelt light option ? maybe thats for the seatbelt light IF EQUIPPED. I know 70s E bodies did.

[BananaDan]

That's possible, I know there is a reverse light option for 4-speeds.  And I just checked, there is. L73 - Seatbelts Unfastened Lamp.  http://1970chargerregistry.com/Production/RT_Codes.html  Whatever the possibility, I think we have sufficient evidence to show that I just don't use that connector and leave it unoccupied and I'll be ok.  BTW, I know there are a lot of connections for option light harnesses to the door switches for grounds and such, but the dash harness covers that IRL.  The two female bullet plugs on the dash harness (one for the maplight harness, and one for the ignition lamp delay harness) both have two wires going into it from the dash harness.  Those extra wires run to the door switches, so I don't have to worry about that connection, it's handled by the dash harness.

For the archives...

I labeled the wires I had to connect, everything else you see is how the fuse box came new.

I confirmed with someone that has multiple A01 B-Body cars, and this extra connector on the ignition delay light harness is unused for an unknown option.

great, at least we know now. thanks for the pic too

[BananaDan]

Correction made regarding the heater blower wire.  See the first message in the thread.

[70charginglizard]

You guys know if anyone sells the A01 harness new?

[BananaDan]

Not that I was able to find.  I asked Bill Evans and he doesn't.

[70charginglizard]

Bummer...u know what they say about weak links....

[BananaDan]

Yeah, but most of those lights aren't used often.  Just make sure you find nice sets.  If you're able to wire yourself, you could get the A01 sets and replace the wires yourself probably.

Update 11/27/18: The unknown wire with spade connection on the A01 harness is for the "seat belt" warning lamp on front of dash for cars equipped with deluxe seat belt package.

Thanks for your very useful post. Much appreciated information.

It not helping!!!!
