I figured I would write this up while my memory is fresh.

Keeping it down to just the colors of the wires is all I am going to for search purposes because I had difficulties finding the info...

If you are wiring on the firewall side of the connector that is under the steering column, the wires are:

Constant 12v = Solid white
Ignition = Black w/red stripe
Accessory = White w/ blue stripe


If wiring into the harness in the steering column(like I did) the wires are colored differently:

Constant 12v = White w/ Red stripe
Ignition = Black w/white stripe
Accessory = Blue w/ white stripe



Harness to turbo timer are as follows:

Constant 12v = Red wire on timer
Ignition = Green wire on timer
Accessory = Blue wire on timer

This is for an Apexi unit, but I found while searching for wiring info that the Greddy and Blitz also use the same colored wires on their units.

Hope it helps someone, Josh

EDIT. The wires for the a/f and o2 voltage. If looking down the wires to the harness, it will look like this.

00000000 0000000 0000X000 00000000G
00000000 0000000 00000000 000000000

the "x" is for O2 sensor, the "g" is ground...Josh
