Harness Questions - extra wires?

[DANF]

I have installed my Yearone engine harness and have a couple leftover connectors.  I have a 6al box therefore I know the ECU connector in the pic is useless but the black connector with the double blue wires and the (4) wire connector with the yellow and blue wires I can't recall where they go.

Other than that I think I have this thing wired.  I'm not sure I would have bought the new harness given what I now know about the 6al box wiring - it eliminates most of the harness wiring.

Thanks

There are wiring diagrams on this site.

conector with double blue ( more really a spliced blue ) wire is to the electric choke control...

I can't see the other plug... your is a 74 right ? as far I recall.

If your is a 74 then that plug with two yellow wires, one black and one blue is to the interlock reset button located normally at a side of ECU module. That reset the start circuit when some fail happens to the seatbelt interlock system

Thanks Nacho.
Yes, 74
Well, the connector with the blue wire answers another question the popped up about the choke wiring - thanks.

Okay - now this "interlock switch" connector. Is it necessary or can I run without it? Can I bypass?

  Let me look at my "before" pictures and see if I can locate that little gem.  I think I recall it on the firewall and it had a little red reset button on it.   I do have several wiring diagrams but could not locate either connector.

thanks

First I need to know:

what interlock control box do you have ? ( blue box, tan/white box orange box ? )

do you want to have your car "interlocked" ?

do you want your car with seatbelt signals and all buzzers ( key in, setabelt, and lights on if equipped ) allowed or you don't care about ?

At the end of that link is showed how interlock unit works ( blue box stated on video ). There is replacement orange box units ( used also on canadian models what weren't interlocked ) that replaces the control box for non interlocked cars but still have the warning buzzers and lights working in order. I got a Rallye harness from Canada with that box attached and have it mounted right now on my car for a while I get the blue box ( I want to keep my car interlocked ). Right now there is a green box control unit for non interlocked cars selling at ebay. Stated for 75 Mopar. Dunno if that will work the same than orange box.

that box is located down the dash frame between glovebox and ashtray.

IF you have a blue box and you want to get rid off that stuff I will be a good recipient of that:

To bypass the interlock function you have LOT of options:
-will need to make a jumper between two yellow wires on that plug on engine bay
-a Jumper on two wires where interlock control box plugs ( yellow and yellow traced )
-relocate one wire ( casuality, the yellow one LOL ) on back of bulkhead
-Unplug the seatbelts sensors harness ( that will eliminate the seatbelts warning signals function too )

The BEST way to keep the warning signals working without touch ANYTHING of harnesses is get an orange control box unit ( or the green on ebay, dunno ). That box already have jumped the yellow wires inside by default. Note the one on pic attached ( this is the harness I got from Canada ) here:

about the choke wire. 73/74 cars with TQs and other carbs with manifold mouted heating coil element, and electrical assistant have/had a control unit that controls the voltage to feed the heating manifold element here is a pic of mine mounted. there is where plugs that blue spliced wire.

is that tan unit mounted on last bolt of manifold... wire pluged is the assistance for the heating element coil. there is anothe prorng there where plugs the blue wire ( on pic is not pluged yet ).

there is two kinds of control units fro choke... single and double stage.

single stage feeds with just one voltage lever untill engine is warm. Is normally used on /6 and SB

double sends two level of voltages depending on engine bay temp. Is normally used on BB cars. does have a ballast attached at a side like a temp sensor

both works the same in the purpouse

there are couple being sold on ebay:
double stage

I know there is a single stage around but couldn't find... sure will do. Just in case I have one NOS.
