(Blitz DTT DC install)
Well, after 6 hours, I was able to finally get my year old TT installed. Yes, as you can tell by the pictures, I'm a procrastinator and I really need to clean my MS3 ...
Jay's write up is solid and I tested the wires to be correct as stated before ('08 here as well)
Black/Reds strip = 12v constant
Green/Yellow stripe = Ignition wire
Yellow = ACC wire
Also to add, these wires are all 12 gauge wire on the car where the Blitz had a 12 gauge 12v red, but the other 2 where 14 gauge. You can use the 10-12 Gauge splicer clams on this smaller wire and still get a solid contact.
So to clear up some things that stumped me. The Hood release should be the 3rd or 4th thing you take off.
1st = driver door skid plate (just pull it off .. it's just plastic pop clip things)
2nd = bottom left panel next to your clutch (you will see a pull out clip right above the foot rest skid plate
3rd = the hood release (just push that button while you pull it towards the driver seat .. that's how it comes out.. not straight down like I tried to do)
Next is the panel below the steering column. The one screw that holds it in (that was covered by the hood release) will now be visible. Just take that out and start pop'n it off.
Then the steering column. The top of the steering column just pop's up (I took a flat head and pop'd it up in front of the key insert.
The bottom column has 3 screws holding it in place. 2 of which you can see and the 3rd is visible after you take that panel off below the steering column.
Here are some pics of my install and hopes this clears up some confusion that others might be having as I did.
Also to add, to get the center console out,
step 1 = unscrew your shift knob
step 2 = pop out the cup holder (they are just attached by plastic clamps and it comes straight up, start by pulling on the end closest to the E-break
step 3 = pull off the shift cover in the same manner
step 4 = unscrew the 2 screws holding the ash tray / lighter assembly in. Pull this out, there is a plastic bracket that hold the upper right corner and I had to pry on this for about 3min before mine actually came undone. After it's out .. just lay to the side, I didn't bother undoing the wires and it has enough slack in it (after the console is out) to be out of the way.
Now you should see the 2 (4 in total)8mm screws holding the console in up front. There are 2 more in the holder at the back(they are in the bottom of that bottemless holder where your aux plug in is.). Once these are undone you can just pull this whole thing out. Don't forget to unbuckle the lighter cable from the harness.
Here are the pics... Yes, it's dirty in there...
Here is all the panels off as a whole.
Here is that stupid hood latch .. this is just to show you how that clip works.
Bottom panel and steering column off. Don't worry the top of the column is attached with some rubber. So it kinda just hangs there in limbo and will totally get on your nerves as you take the harness in and out of the key switch.
Here is the shot of the E-brake. The wire is on the side of the passenger seat, and I actually unscrewed the one screw that was holding that switch in place to get my splice clamp on correctly. 18 or 20 gauge I think.. it's small.
This is the ground I used which is on the left side if seated in the driver side seat.
Harness splice in. My volt meter showed the Red and Black/Red stripe(the wire I use here) to be constant 12v. Yellow showed 12v when key was moved to ACC position. Green/Yellow stripe showed 12v when key was moved to ON position.
Finished .. finally.
I actually mounted my TT box behind the steering column and attached it to the top of the floor vent with 2 sided tape.
Just to add, I can lock my doors with my keyless entry while this is running as well.
I did not hook up the vacuum line though. I need to get a boost gauge anyways and wouldn't feel like moving the line again.
Again I hope this helps anyone that might be having the same difficulty with the panels and that stupid center console as I was. And the wire confusion ('08 sport model).
