How to Hook Up a Turbo Timer

1. Unhook the negative terminal of the car's battery before you begin installation. This is done by loosening the clamp on the black terminal of the battery, then lifting off the cable. This ensures user safety, as well as does away with the risk of electrical malfunction during installation.
2. Remove the plastic covers over the steering column and center console of your vehicle. This will vary depending on make and model. Often the covers are held on by plastic clips and/or Phillips-head screws. Search along the underside for all fasteners. Once removed, the plastic covers should lift free, exposing the vehicle's wiring harnesses.
3. Disconnect your vehicle's ignition harness. This is the wiring harness leading into the ignition's key slot. The ignition harness has male and female connection ports. Separate these by hand, and hook your turbo timer's wiring harness between the connections. The turbo timer's harness has a male and female end so that it will plug directly into the vehicle's stock harness.
4. Ground the turbo timer unit. This is done by running the turbo timer's ground wire to a grounding source. An easy choice is any secure connection to the car's chassis, easily reachable from the steering area of the dash. Wrap the exposed end of the ground wire around a screw or other secure connection to the chassis, and tuck all excess wiring into the dash. Secure with zip ties.
5. Run the turbo timer's parking brake wire through the dash, to the center console area. Splice it into your vehicle's parking brake switch. Do so by stripping roughly 5mm of the parking switch's insolation, then wrapping the bare end of the turbo timer's parking brake wire around the exposed parking switch. Crimp the spliced wires with the wire crimps supplied in the turbo timer kit. If for some reason your turbo timer kit didn't come with crimps, simply pinch the splice tight by hand then wrap with electrical tape.
6. Mount your turbo timer in desired location, and hook into the ignition harness. Tuck all excess wires into dash and center console, then secure with zip ties. Replace steering column/center console covers. Replace negative battery terminal. Start your vehicle and ensure that turbo timer unit turns on and has full functionality.
