Hey guys,

I was changing the light bulb to the left of the oil pressure gauge just above the cigarette lighter and noticed this connector. The wire is green, the connector is black. Did I accidently pull it out of something? I got big thumbs!

Thanks in advance for any info.

Are you sure it's green? If it's really a brown wire, then it's an always-hot wire that connects to a radio capacitor.

I can't find anything that shows a dark green wire with a single black female connector on the end, behind the dash.

 

There should be a radio capacitor attached to the cluster right near where you're male connector is in the photo. However, it's lead should be 18 AWG brown -- not green. The cap has the female connector and ~3" of black wire.

 

Could be brown I'm partially color blind Does someone have a pic of where it attaches or more detail of the location of the capacitor.

Thanks

 

The capacitor mounts to the back of the dash, below the oil gauge.

 

 

Bad news is I don't have that cap

Good news is that my thumbs were not that big after all

Does anyone have a part number so I can order it?

Does it attach to the little screw at the bottom of the back of the oil pressure gauge?

Thanks

 

Corvette Central has it, part number 302162

Yes.

Note, you don't really need this capacitor, but since the brown wire with female connector is always hot, you should at least cover the connector with electrical tape so you don't short the wiring harness out by accident.

 

It would also help in future posts to give us a clue about what year car you have; your post doesn't say, and there's zero information in your profile.

 

Thank you and the first thing I did was tape the connector.

 

My bad, I had a brain f**t. I usually start of my posts with the year of my car (66).

Sorry. This forum is so helpfull so I hate to do anything that makes it harder for the respondents.

 

Guys I looked thru these threads, and pulled this one from July. Im reinstalling my rebuilt 1965 console and it had both radio capacitors but one of them has the wire completly missing from the capacitor. I see that I can order these new, the question is do i need them? My car was converted to MSD ignition but still has factory radio. I also have the one that goes to the brakes.

 

Not really. They prevent static from showing up on the AM side of the radio.

There are many capacitors, you are describing only 2?

 

I saw two on dash cluster and one on brakes, does the assembly manual show all locations? And do I need any of them? I'm installing the new wiring harness this week and also vintage A/C and just wanted to make sure I did it correctly. I have the large version of the wiring harness laminated and harness from M&H and already finished the engine area, now ready for the inside and wanted to know if I need these capacitors and if so I wanted to order them?

 

From memory:
On the cluster under the Oil gauge
On the cluster connected to the Amp gauge
On the cluster spliced into the parking brake light wire
At the brake switch
Above the power antenna switch, connected to the flasher

Yes, look in the back where the Radio installation is shown.

They only absorb noises from the AM side of the radio. If you leave all capacitors off, the worst thing you'll have is possibly some static on the AM side when the car is running, or the parking brake is on, or you hit the brakes, or the signal switch is engaged.

I tend to be "as it was, as it shall be" type of car guy so when I found some missing on my 65, I ordered them and installed them even though I never listen to AM radio.

Thanks and I understand the "as is" comment, and Ive tried to do that on most of the items that I have repaired. Any other "gotcha's" to look for on the dash wiring harness? I have studied these forums and marked most of the old harness etc.

 

Note I fixed your post to reflect my name

I'd recommend adding a 2 amp fuse to the wiring going to the BATT gauge (it's really not a Amp gauge anyway). I added one by just building a fuse holder with male/female terminals, unplugging one of the BATT gauge wires, and plugging in the fuse holder in-line.




My 65 has factory A/C which adds 2 more 0.33 Amp dash bulbs over a non A/C car. Plus, all 65s had 2 more 0.33 Amp dash bulbs over a 63/64. So I had 4 more 0.33 Amp bulbs than a base 63 or 64 and yet the circuit is a 4 Amp circuit in all of those years. I found my car blowing the Panel Lamp fuse until I went to a lower rated bulb AND a 5 amp Fuse. Not sure what your configuration will be, but if you blow the panel lamp fuse when you car is done, first put a multi meter in place of the 4 Amp fuse and see what kind of current you are getting.

When my new LL harness arrived, several of the wires were partially or fully out of the plastic connectors to which they were originally installed. So check all wires to ensure they are snugly installed in any new plastic connectors that come with your harness.

Check each of the bulb holders before you put bulbs in them, to ensure they don't have any stray wires in them that would ground the hot gray wire to the metal bulb holder.

The metal terminal on the glove box light wire is a special terminal that forms 1/2 of the bulb retention track once it's installed in the bulb holder for the glove box light. The terminal and connection is pretty weak, so you may wish to consider moving the special terminal to a larger gauge wire, and then putting a male/female connector in play so that later if you need to disconnect the glove box light from the harness so that you can remove the glove box, you don't risk breaking the wire. Someone previously pointed out that I should have put the male terminal on the short wire, and the female on the always-hot glove box wire.


Watch out for the black ground wire that connects to the grounding tab above the tach, and the dark brown always-hot wire that connects to the radio capacitor under the oil gauge Many have gotten the two wires swapped, which then makes your oil line a ground circuit.

 

Jeff (sorry for putting John)

Thanks, one more question: on the ground straps that came with my harness, I will need to locate the area's to install them, I assume some of them are removed over the years, is there a forum or would you suggest to just use the assembly manual?

 

The assembly manual shows all of the locations. For my 65 with factory A/C, working from memory:

1) Left motor mount to frame


2) Left rear intake manifold bolt to accelerator linkage



3) Center cross member to undercar exhaust clamp bolts

4) Power antenna motor

 

Thanks so much Im going back in the garage to work! I completely stripped the interior and replacing or repairing all items. I have had the car for 2 months and I finally get to start putting it back together Vs tearing out and cleaning and spending $$$ on parts etc. Oh my car has a flasher switch mounted on the overhead panel right next to the dome light is that a option or did someone put that on aftermarket?
