Lets play a game called "where the heck does the wire go"

2 wires here. 1 on the top right, coming off the voltage regulator, the other on the bottom, left, which comes from the front wiring harness.



1 wire here, laying on top of the proportioning valve. It looks like it plugs in right on top of the valve, but I can't seem to get it to click in, and don't want to break anything.



There are 2 wires here spliced into the wiper motor which run across the front wiring gutter and has a connector just laying there. It looks like this was just spliced in for something, though I have no idea why. I'd like to just remove it if possible.





Thanks guys!

Re: Lets play a game called "where the heck does the wire go"

Jason - I've seen a few guys install over the counter carbs with electric choke and steal power from the hot wiper leg but not with a connector like that.

The voltage regulator wire kinda looks like a weird radio noise suppressor but its a strange way to mount it making it look like a ground connection. Mine just clamps under one of the mounting screws. Does your VR has a noise suppressor - can't see behind the wire bundle in the picture.

I'm stumped by the other two brown wires to a single connector. I assume its a female connection? Someone here will know exactly what accessory it powered - My first thought is a novelty horn?

Re: Lets play a game called "where the heck does the wire go"

where on the VR is that thing connected? Top bus or side? Is the clip flush to one side of the barrel of the wire as if you slid it under a bolt head the whole unit would sit flush to the radiator support - assuming it is a noise suppressor and should be mounted under one of the top VR bolts.

Re: Lets play a game called "where the heck does the wire go"

Ok I just hit the garage and on my 69 the brake connector should fit snugly. Try rolling up the bottom edge so the connector is exposed, slide on, then roll down the rubber boot.

Re: Lets play a game called "where the heck does the wire go"

The brake connector won't fit properly, it's a factory connector and boot and the terminal on the aftermarket valve block is different than the factory item.

Well that sucks. The brake kit was from Belair Bobs....I wonder what I have to do to get that to work. Surely I can't be the only one to run into this.

My kit from Bob came with a connector pigtail. Maybe check your boxes again.

It was installed over a year ago, and the boxes are long gone, but I don't remember ever seeing one. I guess I'll email Bob and see if I can get one separate.

Re: Lets play a game called "where the heck does the wire go"

Yes, would be good to know where that first one connects on the VR.

The only brown stuff that is in that area is for running lights (and one in the VR connector). Maybe test it for voltage with key off, key on, lights on, etc.

Tan wire is figured out. Sweet!

Yah, looks like someone needed a key on 12V supply to something. Aftermarket coil, choke, etc.

I love guessing games! lol

Re: Lets play a game called "where the heck does the wire go"

The Tan wire that goes to the differential switch (originally) goes to the Fuse Block. It joins the Tan E-Brake wire that leads to the Instrument Cluster BRAKE warning light. When a leak is sensed in the diff. switch (a plunger slides to one side and grounds if there is low/no pressure to either the front or rear brakes), the BRAKE warning light illuminates.

Re: Lets play a game called "where the heck does the wire go"

By the wiring diagram in the assembly manual the 2 brown wires are part of the side marker lights. There should be a single brown wire there that it would plug into coming from the engine fuse block?

Re: Lets play a game called "where the heck does the wire go"

The cylinder lying on the top of the VR is a radio suppression filter, and as Brian suggests, Post #3, it should be mounted to a VR mounting bolt to ground the case.

These suppresion filters were added to suppress the spikes the mech VR generated when the relay contacts inside opened & closed reducng noise in the AM radio. Another filter is installed on the coil + terminal for the same reason, point set opening & closing. There may or may not be one installed on the blower power wire. These filters were installed on the power supply wire and IGN side because this is where radio gets its power. Modern and aftermarket radios have filters built in plus later models, 1974 and up, came with electronic VR's and electronic ignitions, no spikes.

Along with the filter were the ground straps, the copper braids, from the firewall to engine, one for L6, two for V8, and a strap on the pass side firewall body mount to subframe.

We Elderly mechanics used a simple transistor AM radio to set initial timing. Set the timing marks were you want, ie, 6 BTDC, turn on the AM radio and set it next to the dist, and turn the dist in the normal direction of rotation for point set opening and listen for the 'snap' from the radio. Tighten dist. Done.

Re: Lets play a game called "where the heck does the wire go"

Alright, so I'll connect the filter to one of bolts.
The extra wiring from the wiper motor is getting removed.
I'm waiting to hear back from Bob about the brake light from the prop valve and what I need to connect it.

I'm still confused about the double brown wire in the passenger side headlight/corner lamp area, as all of the lights work fine, and there is nothing matching it to plug it into.

Re: Lets play a game called "where the heck does the wire go"

I had a similar situation with my aftermarket brake switch and ended up using a female single connector from an old motorcycle harness it fit perfect and I also used one on the e-brake pedal switch.
