What is this Connector

[BroncoNewbie1100]

Here's the situation, bought a Bronco in milk crates. It was a 5.0 truck swapped with a 5.8. I put then engine and trans in hooked up everything and I'm left with there 2 connections. I have no power inside the cab of the truck, no lights, a good battery with 12.6v and everything inside the cab is hooked up and hasn't been touched. Please let me know what they are. Drivers side wires look like it's probably the AC parts which this engine doesn't have an AC pump.

Yo B,
Welcome!
What year is it?
I have vision issues, so here are some wiring diagrams for you to peruse for those wires/connector:
Here's the 94 Bronco A/C wiring;

See
Connector Location Diagram, in 92-96 (part of Keyless Entry Wiring Diagram for 92-96; scroll to the right); C200, C1048 (E4OD), C911 (left vanity mirror lamp), C271 (inertia fuel shutoff, C268, C509, C203, & C228, C912 (right vanity mirror lamp), right power mirror, C601 or C608, C404 (rear axle sensor-VSS/ABS), C311 & C310 (rear window defroster), manual transmission, C166 (back-up lamp switch), C117, C441 (fuel pump module), C429 (tailgate power window switch), tailgate window switch, C428 (tailgate latch switch, key operated), G401, C209, G200, C213, C221/C222/C223 (electronic shift control module), C220, transfer case assembly, to C161 (4x4 high/low indicator switch), C1020 (BW 1356 Electric Shift on the Fly transfer case (ESOF) output shaft speed (OSS) sensor location), C1012 (transmission range sensor(TR/MLPS), C214, C504 (left door courtesy lamp), C502 (left door lock motor), C503 (window/door lock control switch master, left), C500 (left window motor), C507 (left door speaker)

The first connector picture is for the blower speed resistor.

The other wires that are bare, not sure yet. Have to look through the wiring diagrams and try to match up colors.

BUT, they have nothing to do with power inside the cab. Need to check fuse box under the hood. If there is power there, then you need to check fuse box inside cab.

Forget those wires and get power to everything first. Maybe take some more pictures. Like does the positive terminal on the battery have 2 wires going to it? One wire to the starter, one wire to the fuse box?
Or is there a starter solenoid on the pass fender, how many wires on each side of that?

So depending on year it can help us a lot.

We are just shooting in the dark here.

Thanks for the reply

Its a 1983 original 5.0 truck.

There is only 1 wire on the battery terminal that goes to the starter solenoid then to the alternator which then goes to the resistor pack? Photo below which then leads into the cabin.

 

[Tiha]

Where is the photo? LOL

The starter solenoid, One side should be the wire going to the starter all by itself.

On the other side, every wire with a bigger eyelet on it should be there. The battery wire, alternator wire, should be some smaller wires as well, that are actually fusible links.

They didn't upload the first time, here they are. I did a conductivity test on the fuse link and I have connection for on some to the other on it.

 

[Tiha]

In your picture it looks like there is only one wire on the battery side of the solenoid?

In the random internet picture I grabbed there should be at least one more.

In the wiring diagram attached there should be 2 more.
A fuseible link/yellow running to the EEC relay and Black and orange running to the voltage regulator/alternator.

The fusible link running to the EEC relay is why you have no power in the cab or ignition switch.

Can't tell from the picture, but the other side of the solenoid should go to the starter not the alternator.

Ok looking at the photo actually makes it clearer then looking at the truck lol there is no power going to anything but the solenoid. So I should run a wire to the fusible link? It you look by the blower there is a cut red wire looks maybe to be 10g or 8g. Could that be the wire that should be connected to the battery side of the solenoid?

 

[Tiha]

Okay there is a lot going on there.

See attached picture.

Wire #1, where does this go for sure? You said earlier to the alternator. It should be going to the starter.

Wire #2 These are fusible links. Where do they go? looks like the come from the loom that goes over the solenoid. Do they pop out anywhere around the solenoid? Or do they run too and possibly splice into wire #3?

Wire #3 This is what you are asking about running voltage too. You can, strip it back and jumper to it, see what turns on. If it melts your jumper wire, then probably not it. LOL

Wire #4, not a wire, but this is where the blower resistor is and the connector from the first pic goes to.

Success..... ish, now I have headlights and dash lights. Highbeams say they are working on the dash but I only have 2 bulbs in 1 on each side. I found an orange wire in the looms near the fusible link and was able to connect that to the battery and it gave me power in the cab. I have headlights dashlights windshield wipers, No blower power and no start but I don't have the parts for the shifter linkage yet to make sure it's in park. I did put in a new neutral switch since the original one was ripped off so I'm hoping it will start when I get the shifter linkage and put the carburetor on.
Any reason you can think why the blower won't work?

 

[Tiha]

Did you plug that blower resistor plug into #4 in the picture posted above?

 

[BroncoNewbie1100]

Yes I did, I also connected the loose wire to battery and no reaction at all.

 

[Tiha]

Well then you will have to start with the basics.
Is the switch bad, have to test for voltage across it.
Is the resistor pack bad, have to test voltage across it.
Is the blower motor bad, have to check voltage across it.

It looks like power comes from ignition switch, through a 30 amp fuse, to blower motor and then to resistor pack and then back to the switch and grounded from there.
So maybe first thing is turn the key on and put a test light on the blower motor. Should have power on both wires going to it.

Thanks! Making progress, now I have headlights and the starter solenoid is clicking. I'm checking grounds and going to take the intake manifold off and put some motor oil down each cylinder. The engine was rebuilt by someone before I got it and never ran over a year ago. It's been sitting with no carb in NJ outside, hood on but high humidity might of locked it up a little.

This is a very satisfying build as it was a roller with parts, nothing labeled and I'm flying blind with a generic bronco manual that covers 15 years of models

frustrating (esp as received) but each victory makes ones day ! Congrats on the successes (wiring/ele is my worse).
