hey, i just picked up a FET TB308 turbo timer and it did not come with the harness, just the wires and no instructions…so i wanted to ask if anyone else has installed this turbo timer in their 240?

here are some pics:

there are 5 wires:

1. black - ground

2. red - constant 12V power source

3. white - to handbrake sensor?

4. blue - something with ignition?

5. yellow- possibly speed sensor?

so my question is this kinda right? i looked on the internet and there are no wiring diagrams or instruction manuals for this.

thanks in advance!

Hey I never have istalled one like this but seems that the color are ( followed by my apexi turbo timer)

1. black - ground

2. red - constant 12V power source (from the ignition harness)

3. white - 02 sensor (white with brown strip on sr)

4. blue - 12V power source ( u can get from ur acessory harness)

5. yellow- ebrake ( I think is the yellow with brown wiring pluged on the ebrake)

As I said “I am not sure” but try this way it seems to be the right way to make ur turbo timer to works.
