HELP! ....New 70 engine wire harness connection questions?

[70charginglizard]

HELP!

I just bought a new engine wire harness for my 440 magnum and I've got some connections I can't find hook ups for. One is a Grey/black wire that runs from what I believe the negative on the coil??? to the firewall connection. But before it connects at the firewall it comes out of the wire harness and has it's own miniture connector that doesn't seem to have anything to connect to on my car.

What is that grey/black wire for?

Another one is two blue wires comming out of the harness between the coil and the aft end of the motor.

What the heck are these two blue wires supose to be for?

My old harness didn't have either one of these connections. So what is up?


Everything else hooks up and is accounted for.

the grey wire usually hooks to the tach but the tach generally didn`t go through ther bulkhead connector & had a separate wire & grommet , the harness may fit another application & be routed differently on your car
the olny reason I can see the blue wire being where ti si is to hook to an electric choke , these were not used from the factory but a lot of aftermarket carbs have them , I would just tape it into the harness

The gray wire connector does hook up to the tach wire that comes out of the tach wire grommet about 2in.
You don't have that yet, Charger Specialties sells the harness and plug all as one unit.

Or use it for my edelbrock electric choke??? On my old harness I only had one wire going to it that I put in and routed from the balast resistor. but these two blue wires don't seem to come from the balast resistor???

The blue wires are maybe for the idle solenoid on a 6 pack car???

that plug by the firewall is either for A/C or hood turn signals - i forget which...      pretty sure A/C

wires are too short for the 6 pack solinoid
