Australian Passing Flash Modification - Version 2

How to rewire the Aussie headlights to raise when flashing your highbeams.

This project compliments the 'fog lamp' modification but can be implemented solely because of appearance reasons.

I originally decided to implement the 'fog lamp' modification as one of my first changes to the lighting system. But whith this mod came the problem that when I had the fog lamps on, how could I then flash any oncoming vehicles? This is the solution which allows for the pop up headlights to raise and all driving lights to illumintate on a stock probe. And in my case, only the lights within the pop up headlight assembly

Task at hand;

1. Install an additional lead from the high beam Cct(R/W) wire to the CPU brd(CN3).
2. If you are currently using a power diode for the original 'flashing' mod that I designed, then remove this as it is no longer required.

Firstly remove the battery connections to prevent any possible shorts that may occur.

Removing the plastic cover beneath the steering column will allow you to isolate the required connector. A single screw located near the lower left of the plastic trim and the bonnet release mechanism will need to be removed.

The footwell plastic trim also needs to be removed to allow for access to the CPU brd which rests on top of the Fuse panel assembly. Two plastic clips hold this panel in place but its a good idea to remove part of the lower sill plastic.

Now unplug the CPU brd from the fuse panel and remove its dedicated connector.

This is the CPU brd that we will be working on.

Close up shot of the connector(CN3) we will be using including the required solder point(3b).

CPU modification complete, re-assembled and ready for installation.

You will now need to locate the 'High Beam' (R/W) lead which is shown below. I made use of this connector as it was the closest to the CPU brd, thus less wiring required.

Close up of the connector.

Splice the R/W(High beam) wire and solder lead from CPU brd(CN3) to this as shown.

Now re-install connectors and happy flashing.

NOTE: The CPU Brd used in this modification is from a 97 SV probe. I cannot confirm whether earlier model probes use this same CPU brd but will endeavour to source this information.
