ok i can help you with the main turbo timer part, i know what you are going through, i had the same issues.

1.you will have to start by taking the plastic cover off that has the hood release on it.

:ATTACHING THE IGNITION WIRE:
once you have removed that you should be able to see your steering colum and all that, on the steering colum or near it there should be a big black connector that has alot of wires comeing out of it, probably 12-18 wires. disconnect that and look for a black with orange stripe wire on the connector closest to the steering wheel. "i recommend useing a vampire splicer for this.

:ATTACHING THE E-BRAKE SENSOR CABLE:
take your dash apart by unscrewing all of the screws and then pop that baby off. By your shifter there will be 2 screws, take those off. next inside the mini compartment by your tems unit switch there will be 1 more screw that you need to unscrew. pop off your shifter console. Now if you havnt already done so take off the e-brake cover, now down by the e-brake you will see a little sensor that kinda looks like this

its small and black, looks like a push button, and its near the bottom of the ebrake
you will need to use another vampire splice connector for the wire comming off of it.

:POWER AND GROUND WIRE:
find yourself a ground and a possitive and hook it up.

before you start to put everything back together put your key in the igniton and turn it to the ON possition, the turbo timer should turn on. then take the key out and it should start to do a count down.

if the turbo timer didnt turn on, make shur to check your possitive/ground/e-brake sensor

if all else fails i forgot to add a step. hope this helps your, ill add more to it when i figure out how to hook up the speed and RPM signal wires up. Good luck
