installed blitz fatt dc3 but...

[dsmgod87]

i installed it correctly and everything but on the control unit there is an a/b switch and the turbo timer wont turn on unless it is on B but then it wont count down. the car just shuts off. but if i turn it on and start the car then switch it to A it will start counting down then i can turn the key off and the car will remain running. why is this? i have an autostart alarm installed could this be some of the problem?

ya same here seems like it wont turn on in A mode and but it wont count down in B mode. the A mode which counts down correctly doesnt get power or w/e. but i can get a quick jolt of power to it if i disconnect the ground the reconnect them i get power for a split second. is it a bad control unit?? neone please

I bought a used FATT and it did not come with wiring instructions!
do you guys know what the purple wire is for??? the one coming from the control box? Is that supposed to be wired to a constant power source???
I have two ground wires! Which one do I run to the E-brake???
