Valvetronic Switch


rmoudry

Recommended Posts

I have a valvetronic exhaust installed on my 2004 996tt. The "on-off" switch is currently wired to the parking light positive, which means in order for the switch to function, the parking lights must be "on". Can anyone suggest an alternate wire in the engine compt that I may tap into that will be fully functional when the engine is started, or the key is turned to the acc position?

I would really appreciate some advise.

Thanks

Under the forward center console is a plug for the factory cell phone setup, which has an ignition switched lead. Plug wire colors: Brown = Ground, Red / Green = Switched 12 volts, Green / Black = Unswitched 12 volts, Yellow / Black = Telephone Mute. Tap into the Red/Green wire and you are in business.

Thank you for the reply. Is there any wire in the engine compartment I may use rather than run the wire all the way forward or, do you know of an easy route from the engine compt to the location under the center forward console?

Thanks again.

Ummmm..........you just need to run the wire from the cell phone connector to the dash switch, not all the way to the rear of the car as the switch should already have one wire going back there.

If you don't have any wires running to the back, there are multiple bulkhead rubber plugs that you can route the wiring through...........

Sorry for not being more clear. The "switch in the cockpit" is a remote which activates the actual unit that is in the engine compartment. There in lies the problem. Any ideas?

OK, I'll take it that the "remote" in the interior of the car is not hard wired to the unit in the engine bay. The "OEM correct" set up is a dash switch that is connected according to this factory wiring diagram for the factory installed PSE:

The wiring from the switch runs to the PSE vacuum control unit in the engine bay (orange plug to the right of the power steering):

And the factory dash control switch looks like this (the $25 OEM switch on the bottom):

Having installed a couple of these, you are going to need to run wire from the dash to the engine bay, and that will need to be "fished" along the interior rocker panel area to the rear bulkhead and then through one of the bulkhead plugs I mentioned earlier to reach the engine bay, or ordering the PSE wiring harness (P/N 996 612 978 00) for under $20, and a dash switch ($25), and plugging it into the relay block.
