DIY LOC input harness for rear speakers (No cutting, no splicing)

[Jason@JacFab]

My car doesn't have the BA system, so I had to use a LOC to add a sub/amp to my car. I did not want to cut, or splice ANYTHING, so I did a little research, and made my own harness...

I was not able to find a source for the actual Chevy rear speaker plugs (male or female), but here's what I ended up using:

Female: Crutchfield p/n: 12071048 $12.99
The Crutchfield site actually said that these would fit for the Camaro w/o the BA system, but I did have to modify them slightly. (GRIND CORNERS FLAT)

Male: Motorcraft (Ford) p/n WPT-966, these are about $15.00 each, but I found a set on ebay for $4.95. (CUT NOTCH ONE SIDE)

It's a pretty easy process, pics below should give you the idea of how to make the harness, and the modifications necessary to the plugs.

I used a ******** drivers side enclosure, an Infinity 1262 12" Sub, and Infinity 1300a amp. I'm sure it doesn't sound as good as a system without a LOC, but with limited options, I think it sounds great, and made a world of difference to the stock non BA system! I still need to clean up the wiring, and get some shorter RCA's but it's in and it works!

I am confused?? this seems like a lot of extra work. I have the non-ba system as well,
and all i did is get a pair of crimp plugs from radio shack ($2.98) and a metra LOC ($19.98).....done. took me 5 min. to plug these pieces in.

It may be... It took me about 20 minutes to make the pair, but it's how I wanted it done. No cutting, or splicing. Just personal preference.

Well done. This is exactly what we were going to do for our add an amp harness for non ba, but our harness maker could never find the right plugs. Do you miss any beats by only tapping one speaker? I assume the rears are stereo and not mono on non ba so it's possible you are. If you did both, you would be fine.

I made 2 harnesses, one for each speaker (L & R). Sounds fantastic to me. I used a PAC SOEM-T LOC for what it matters.

While these plugs are not exactly the same, they are VERY close, with some slight modifications that Chevy must have specified for some reason. These are Ford plugs, I also was not able to find the exact Chevy plugs. Had you offered this harness for sale on the ******** site, I would have bought it for sure. But I enjoy making random crap like this, and I figured I'd put it on here for anyone else that doesn't wish to cut, splice, or tap.

For what it's worth, the larger connector you used is what we use for the front door adapters. metra 72-5600. I am hoping metra makes the smaller plug since I have an account with them and get a little break on price.

Did you have to modify it for the front adapters (IE cut notch pictured above)? You'd think they'd use the same connectors throughout the car.

Will it fit 2014 Camaro? And can you post link for Male: Motorcraft (Ford) p/n WPT-966. I searched a lot of websites but none of them has picture of connector so not sure if its correct. I wanna do something similar in my 2014 1 LT non BA camaro.

They have them on amazon, just search motorcraft wpt-966. I just bought some yesterday. I believe it was under $10 with amazon prime. Will see if they fit my 2014 SS. I'll keep you posted once I get them and do the install.

As I've noted you have to slightly modify the plugs, it's not a direct plug and play, but still beats cutting and splicing in my book...

This does still work on the 2014, I just plugged the set that I made in on my 14 1LT a couple weeks ago with no issues.

I don't have a link to the Ford connectors I bought, I bought them off ebay a long time ago and they only had 2, pretty sure they were pulled from a junk yard and not new.

I'm gonna be using a Scosche LOC80 for a mono amp to power a single sub, do I still need to tap into both speakers or can I do just one?
