How do you install a turbo timer to a 180sx?

Answer 1

The main issue in the installation is the wiring. Three of them must be hooked into the ignition switch. To access the wiring you must remove the 2 lower panels underneath the driver side dash. Reaching your right hand up approximately behind the ignition switch, you'll grab hold of a bundle of wires (and also grab hold of the most slimy substance known to man -tape residue-) If you trace the bundle back to the switch, you'll feel a large round connector, about 2 inches in diameter. There are no clips holding it on, so you can wiggle it off. This allows you to see all the wires and attach the taps with ease. A word of warning! DO NOT take the connector apart. I did so in order to trace the pins (you just see a mess of wires coming out of the plug with no real order to them) Unfortunately, the pins inside are held on by the cap. Assuming you are stupid and attempt disassembly, wires will spring out, leaving you to figure out their proper place. Upon reassembly, you will then find that simply inserting your key into the ignition will cause your car to start :freak: Naturally, this would only happen if you were silly. On to the wiring. There are 4 main wires that require hook up from the unit.

1.) Red - Constant 12v

This wire hooks to the beefy red wire coming out of the switch. There are actually 2, and I found it didn't matter which one you chose, both are constant 12v

2.) Blue - Accessory Wire (Becomes active when switch is in #2 position)

This is a beefy black wire, only one coming out.

3.) Green - On Wire (Switch in # 3 position)

Blue wire with red stripe.

4.) Black - Ground

Since I put my controller in the center console next to the lighter, I mounted it to a metal post inside.

Place your ignition switch back on, and then route your wires to wherever your unit will be (up and to the right is a pass-through to the center console).

Additionally, there are 2 safety wires, a brown one for the parking brake signal, and a purple one for the speed signal. These keep the car from being driven away while the TT is still running.

5.) Brown - Parking Brake Safety Wire

Unscrew the 2 torx screws holding the tray underneath the brake lever. Detach the clip at the front holding the tray to the front console (right in front of the fuse box) You can now lift out the tray and you will find a brown wire running from the parking brake safety switch. Tap into this wire with the brown wire from the TT.
