I got a hold of an Blitz MSTT ( Multi speed turbo timer) the other day and cannot find any instructions for use or install, if anyone has one and could send me copies of the manaul I would thank you.
BUMP, I also need to get a wiring diagram on hooking up my apexi… lokied on alldata but couldnt find anything good… Help us out here
From Turbo Timer - to Ignition
Red wire - White wire (big fatty one close to where the key goes)
Green wire - Black wire yellow stripe
Blue wire - Yellow wire
Black wires - Ground
Then the purple wire with the bullhead fitting goes to your ebrake.
This is a lot easier to do if you take off the ignition harness. SHould be held on by two 6mm screw type bolts. And one also attaches this little black box to the key cylinder I believe. The just unplug the rest.
I know the wiring is right but I may be alittle off about how many bolts there are. I’m doing this off the top of my head lol…
Hey thanks a lot for the Instructions when I got mine it came with some garbage… mine didnt come with these and i got in new… weird o well thanks again
read the instructions but they require that threewires be plugged using a harness(sold seperatly) so iguess im wondering if anyone knows which wire goes where
They make a jumper harness, but it’s not available for our car. I didn’t understand the rest of the question.

this is off of a Audi website, most wiring is going to be the same, except I’m pretty sure that we need to use both green and blue wires. 1 used on ACC and the other for ON/START.
Most (verify before you take this as fact) Turbo Timers have a standard color coding for their wiring which is:
RED - Constant 12V
- Purpose: Supply power to the turbo timer
BLACK - Ground - Purpose: Supply ground to the turbo timer
GREEN - Ignition #1 - Purpose: Supply power from the turbo timer to the car’s ignition wire when the key is removed, thus keeping the car running.
BLUE - Ignition #2 - Purpose: Appears the same as GREEN
GREY - Emergency Brake - Purpose: to shut off the turbo timer (& engine) when the e-brake is released.
I also had a WHITE wire for connection to O2 sensors to determine A/F.
GREEN/BLUE: I never checked, but I assumed they both sent the same signal at the same time. Well, it appears that some cars require two connections (I still don’t know the details), but nonetheless, we only need to connect one. Following what others had done, I used the GREEN and did not use the BLUE. The RED, BLUE and GREEN wires on the Turbo Timer are short as they have a plug on them designed for a harness connetion (which most Turbo Timer companies don’t make for Audi’s). Therefore, I cut off this plug and added a length of 14 AWG wire to connect between the Turbo Timer’s GREEN wire and the Black Ignintion wire.
RED: I connected directly to one of the constant 12V posts near the fuse panel. This is the feed that supplies the fuse panel and thus you should add a inline fuse holder if you connect here. That’s what I did. (see image below)
BLUE: Not to be used, I cut it shorter, and wrapped the end with tape.
BLACK: I connected the ground to one of the car’s official ground locations which you’ll find througout the car as bolts in the frame with multiple brown wires going to them. I chose the one that’s located on the transmission tunnel, just to the driver’s side of the gear shifter.
GREY: The A’PEXi manual stated that the Emergency Brake connection should be to the switched wire that has 12V when the E-Brake is up, and Ground when the E-Brake is down. I tested our E-Brake switch to find that it is floating (doesn’t connect to anything) when the E-Brake is up, but does connect to Ground when the E-Brake is down. I determined this would work just fine, and sure enough it does.
With the above 4 wires (RED, BLACK, GREEN, & GREY), the turbo timer will work. That is, it will keep the engine running after you take the key out. It will also shut off the engine if you release the emergency brake.
Thanks for the help.
i ended up tearing apart my ignition switch (behind key cylinder) inoder to solder the wires up and that sucked… my soldering iron wasnt hot enough to melt the solder that was on their soo i got out the wiring diagrams and found where the igntion switch hooks up to the near the fuse box (near clutch pedal, just above it are a bunch of cennectors and the igniton switch connectors are 4 fatter wires [white w/black, white w/red, yellow, and black w/yellow] and I tapped into those lines I cant see why this isnt an easier soulution to tearing apart the dash… but i hope this helps you guys…
Red (BAT-B 12v) = white w/black line
Grn (IG1) = Black w/ yellow line
Blue(IG2) = Yellow
Black(Apexi ground) = Black wire off ecu for ECU Ground(or anychassis ground if O2 options isnt being used)
Gray(Ebrake security) = parking brake switch
White(o2 signal to apexi unit) = White off ecu o2 sensor signal wire to ecu
i also just got a MSTT and was wondering where you connected the Orange wire to? its for speed input from the ecu, its to record 1/4 mile and 0-60 times. i know it goes to the ecu as shown in the diagram but what wire do you tap into through the ECU?
