I ran the wiring behind the heatshields and above the tranny to the shifter cutout. I have an auto, so I just removed the shifter and fished the wires through.
I used the cig lighter in the center console for power, and put the switch in there also. There is a plastic piece on the driverside that pops out.

You mean you just removed the shift boot or the entire shifter?
As for the cig lighter you just spliced into it, taped it back up?
That's a great spot for the switch.

Had the Boss 302 Side Exhaust and QTP Electric Cutouts installed today, pretty easy set up. But because I don’t have the right equipment at my house I took the Pony and the set up to my exhaust guy. Tomorrow I’ll finish up the wiring, get pics and vids posted within the next day or so.
A couple of things we ran into with the install of the system. Nothing major and all the directions I found online were pretty straight forward. However, we decided to make a couple of mods to the install.
My Mustang is lowered with the Ford Racing Handling Pack which is a total of 1 inch all the way around. And why I made one of the decisions below.
The directions call for the removal of the LH and RH heat shield we decided to keep them and modify them so that the side exhaust fits nicely. It looks good and keeps some of the integrity of the shield.
Next we noticed that the QTP sat at an angle when installed. For a quick reference look at the pictures posted on page 13 (https://themustangsource.com/f800/bo...03279/index13/), you will notice there is an angle to the entire QTP and for me that means the QTP was hanging 1.5 inches below everything else on the Pony. I can’t imagine having that caught on something and ripping off. I know probably never happen. But I wasn’t going to take a chance.
To fix this issue my exhaust guy cut the flange on the h-pipe and then rotated it until the QTP was parallel/flush with the bottom of the Pony/ground, then welded it back in place. I must say it looks much better than the two QTPs angled down.
If the Pony wasn’t lowered I probably wouldn’t care about the angle.
If you look at page 8 (https://themustangsource.com/f800/bo...503279/index8/) the QTP look flush with the ground. The video on page 16 (https://themustangsource.com/f800/bo...03279/index16/) shows them flush as well.
I’m not sure why there is a difference and I’m curious to know if anyone else ran into this problem. The one thought I had the reason for the difference is the Boss is actually set up a little differently for the QTP to sit flush. IDK
Anyway I’m pretty excited about wiring it tomorrow (just ran out of time today) and hearing how she sounds. Pics and vids to follow.

I believe kooks has a setup for the side exhaust as well. Any ideas how this compares? I was considering ordering this whole setup along with a Roush TVS:

http://www.redlightracing.net/kooks-...-8in-11-14-gt/
http://www.redlightracing.net/produc...%252d14-GT%29-
Do you guys think I should go for that to help the car breathe, or will their be any benefit in doing the side exhaust setup without headers beyond the awesome sound that i'm not aware of?

Okay my verdict on the side pipes.
Maybe it’s my exhaust (Flowmaster 40 Series), but there is no drastic change in sound when the QTPs are open. It’s a little more of an aggressive sound, but not overwhelming or that much of an increase in sound. IMO
Hindsight, I would not have gotten the QTPs, I would just have removed the restrictor plates and then got the QTPs if I thought it was too loud. But it isn’t, a little disappointed in the fact that I thought it would open up the sound more.
I’ll work on some videos still. But what I have played around with so far, I’m not sure you would be able to hear the difference.
Don’t get me wrong there is a slight increase in volume, but not worth the price of the side pipes and QTPs. Maybe there is a bigger difference with a stock Boss.
My suggestion if you go this route, just go with the side pipes, take out the restrictor plates and then determine if it is too loud. Or just save the money and put it towards new headers and the entire exhaust system.

I kinda figured that would be the case, I was thinking of doing the side pipes w/o restrictors only without the cutouts, and if I thought it was too loud I would get them. How happy are u with the new sound? Worth it??

I'm okay with it, just disappointed really. I thought it would be much louder than just the axle backs, but it's not. Is it worth cost, IDK probably not. Money could be better spent saved up for headers, x-pipe and you would probably get a much better sound, not to mention much louder. If you do it, don't get the QTPs just take the restrictors out and see how it sounds. If you think it is too loud then go for them.

I already have borla s types, so was deciding between the full catback of borla (over axle and x pipe) or just the boss quads......... Cost is almost same, so I wanted sound for sure.
Maybe I should get the borla pipes instead...... Hmmm
Could you please post a vid???? I don't care if its bad quality
