99 Bravada Dash Speaker Harness
 

So last week I decided to replace the door speakers in my 99 Bravada. Those went in well. I ordered a aftermarket wire harness adapters from Metra and the factory speakers just unplugged and the new ones plugged in just fine. There is two wires on one end of the adapter with a small piece of metal wrapped in insulation. You slide that over two metal prongs on the back of the speaker and take the other end and clip it into the harness in the cavity. A few days ago I ordered JBL Stage 6402 dash speakers with the same adapter because they worked with the door speakers and they fit and line up with the screw and bolt holes but the harness in the dash is the same type as the adapter I got. I believe they are both female so they won't fit. My dad said i should splice the wires after cutting off the harnesses but I don't have a soldering iron nor do I have the expertise to do that and neither does anyone I know. Any solutions?

That look like an unsealed metri-pack 150 connector but not the standard ones. What you have in your hand looks like the male connector 12064778 (or 12052833) (see below) that could mate with connector 12052832 (see below).

You do it nicely and get the right receptacles and the male and female terminals. Or, you could cut and make your own connectors using crimp connectors you find at the hardware store.

I've attached the schematics from my GM Service Manual for your Bravada too.

Ok I'm not trying to cut anything. With those adapters will I be Able to connect the speaker to the wires in the dash? The picture is of the dash harness but the clip on the harness for the speaker is the same type but black. It's made by metra

BTW the reason I've been able to help with this is that I've recently made a study of the types of electrical connectors used by GM in our vintage vehicles. I had to learn all about the Metri-Pack connectors for a project of mine. This document was super helpful. https://www.reynoldsonline.com/ASSET...33769_Spec.pdf However, it appears that the connectors for the speakers are not in the document and are more specialized.

But to start, are these the Metra adapters? Metra Part # 72-4568 | GM wire harness | Metra Online

If so, it looks like they used the Metri-Pack 150 connectors 12052833 http://terminalsupplyco.com/_assets/...2052833_TH.JPG and created their own pig-tails. The problem, it appears what Metra made only works on the door speakers because of the gender of their receptacles being male for the GM end and that the clip mechanism that keeps the receptacles together is different than what is for your dash speakers; i.e. the receptacles to which the Metra ones would connect are these 12052832.

If you don't want to cut anything, you'll have to create your own adapters.

From my GM manual and a bit of online sleuthing I think I found a solution.

The connector at the end of your speaker wires is this: p/n 12064778 made by Delphi/Packard and I think now Aptiv.

You will notice there is a key-way on the top of arched part in the 12 o'clock position with a retaining clip that goes over a single barb on the mating receptacle in the 6 o'clock position. And this takes male terminals. Is that the case for you? (Male terminals will have pins inside the opening that goes to the speaker.)

This geometry is not in the normal Metri-Pack 150 catalogs. https://www.reynoldsonline.com/ASSET...33769_Spec.pdf

However, I was able to find what I think is the mating piece. It is part number 12059253. (https://www.mouser.com/ProductDetail...jcpXmtdQ%3D%3D)

This receptacle takes female terminals. More image files of it can be found here: https://ecat.aptiv.com/product/12059253


Now, according to the data sheets 12059253 mates with this piece which looks a lot like what you have at the end of your wires and uses male terminals, pn 12059254. https://ecat.aptiv.com/product/12059254

The thing is, this mating part is not the same part number as 12064778 but they could be functionally the same.

What you would need to make your own pig-tail adapters is the following pieces, all available from Mouser.com

• 2 of the 12059253
  • https://www.mouser.com/images/delphi...12059253hs.jpg
• 4 of the metri-pack 150 female terminals 12047767 or 12064971. The former is for wires with 0.80 to 1.0 mm^2 cross-sectional area and the later is for smaller wires with 0.35 to 0.50 mm^2 cross-section. (You can look up online the corresponding gauge for these sizes but I'm guessing you'll need the smaller.)

• 2 of the Terminal Position Assurance parts 12047664
  • https://www.mouser.com/images/delphi...HS12047664.jpg

I'd suggest getting extras of the terminals as you will mess up a few in the process of learning how to do the crimps on them in a small and tidy way. The pdf document will show you how these all go together. https://www.reynoldsonline.com/ASSET...33769_Spec.pdf

Good Luck!

Thanks for the reply. So it seems like the easiest thing to do would be to cut and crimp the wires. I know there's kits you can buy that come with cutters, strippers, and little connectors to crimp onto either side of the wire. How difficult would it be to snip the clips off the dash wires and the speaker wires and crimp them together with the kit? Or (and this may sound stupid) is there an adapter that has two female connectors to join together the two male connectors?

It is super easy to do the cutting, and then crimping on of your own fittings.

If you don't want to cut off the original connector, you could separate the wires as they are and then tap into them using something like these: https://www.newegg.com/p/36M-005G-00229

Any hardware store will have a kit like this (below) that is super inexpensive. https://www.walmart.com/ip/Ancor-120...-Tool/33277875

Just be sure to get some more of the correct spade crimp connectors that will match the connectors on your new speakers.
